India Climate Data

My blog statistics have revealed that many viewers have reached my site in search of climate data for Indian stations. The best way to get this information is to visit the official web site of the India Meteorological Department at www.imd.gov.in, and go to ‘Climatology’. There you will find four links: Climate Profile of India, Climate Data of Important Cities, Monthly Mean Data of Important Cities, and Climate Normals. You can choose what is most appropriate to your data requirements. If you need data that is not provided online, you can click on the link ‘Data Store’ at the top of the web page.

    namaskar sir.
    i am currently organically farming in bababudan hills of western ghat in karnataka.
    We are at an altitude of 1500 to 1300 mts with avg rainfall of 80 inches, but 2-3 months of heavy mist. Its hard to categorise this type of climate. i was wandering if you could help me pin point my microclimatic condition of the region (https://www.google.co.in/maps/@13.4149813,75.7314435,355m/data=!3m1!1e3).
    i would also appreciate any extra form of information regarding the weather patterns.
    many thanks.

    Sir,
    When and what was the highest ever recorded minimum temperature in Chennai?
    Is there any link to refer to?

    What could be the (geographical!) reason Chennai always records highest min temp, especially May/June, when compared with other coastal areas in TN? It’s always a couple of degrees above other areas.

Please discuss your problem with him. Ideally, before you decided the topic you should have made sure that you will get the data that you need. Now you have to explore other options.

      Let me explain what I wrote. When you want to go flying to a place, don’t you first know that it has an airport? If you are going to a village, would you find its name on an air booking web site?
      Now similarly, if you are writing a thesis on the solar radiation at Salem, should you not care to find out if the data is indeed being recorded there? How would you get a link to something that does not exist?
      If you are a Ph D student, I presume you have a guide, who should help you in such matters.

      Dear Mr Garg,
      Your requirement is very vague. Do you want district averages or data for individual stations within districts? Do you want current realtime data or archived data? If archived, for how many years? Hourly, daily, weekly?
      How long will you be in the Netherlands? By the time you collect all the data, your course may even be over!

    Dear Prof. R R Kelkar,
    very recently i started looking into your site and I sincerely appreciate these initiatives and meanwhile we are an Olive Plantation Co. based in Zaragosa, Spain and do have our office at India. we are working on to bring Olive cultivation to “MICRO CLIMATE ZONES” in North,South & Western India.
    your informations are very good to understand.
    I would like share about your blog to my colleagues in Spain and others located in Africa & US,South America where we have large scale olive cultivation.
    Currently we focus on yercaud Mountains of Tamilnadu, Kil kotagiri of Nilgiris,
    Kuppam of AP, Nananjgod & Chamraj Nagara of Karnataka, Udaipur of Rajasthan ( closer to Mt.Abu). studying the possibilities in Nasik,Jammu,Samba & Kathua areas.
    Our challenges are basically extreme Heat of above 42 degree C in APRIL-JUNE where flowering initiates and in cooler zones where its lesser than 32, the rainfall is very high over 1200 mm-1500 mm which is of higher side.

    I recommend you to visit our website http://www.agrolainez.com .and my mail ID is

      Dear Anu,
      Daily data for 50 years works out to 365 x 50 = 18250 days. Multiply by the number of metros. I assume here that you need daily average temperature. If you need for every hour during the day, then multiply by another 24. Surely, IMD would levy a processing fee for so much data. Do you have a plan for using such a large volume of data? You are only doing an M Tech and not a Ph D. So be practical, I would say. Ask only what you really need and can really use. If you ask for less, you may get it free!

      Dear Aman,
      I hope you realize that designing an airport is not child’s play. You have not told me where you are based, but I suggest that you visit Patarpur and find out things for yourself, rather than expect all data to be downloaded to your computer.
      The type of wind data that you need for an airport design will not be available on any web site because nobody wants it, except a few people like you. You may give a Google search for “Delhi wind rose”, whereby you may stumble upon some useful information.
      I don’t think I can help you further in the matter.

        Dear Aman,
        If there is already a non-operational airport at Partapur, the wind data should be available there itself and you can collect it. You can at least find out the alignment of the runway there. That should help you. Otherwise you can use the available wind data for Meerut or even Delhi for your design studies.

    I want to dig a well or a tube well but don’t know how to get sweet water.
    If I dig for about 10 feet then I get water which is not very salty but still not drinkable.

    Apart from the 14 stations which receive 5000 mm rainfall, i have done
    research which took me nearly 3-4 weeks to obtain authenticated data from various sources to see whether other places that receive 5000 mm apart from IMD’s 14 places and in the process have uploaded the state wise rainfall record holders. This report will be updated often and popped up as soon as i get more data from public.

    Dear Sir,
    I am Ishita Jain and I am a 2nd year architecture student. We have Climate studio this semester where i have to design a vocational centre for women in Leh, Ladakh. The program that i narrowed down was soil preservation through plantation. the site that we have been given is a stepped site. where the distance between the lowest and highest point is six mtrs. hence i figured i could use the concept of terrace farming and at the same time plantation, strategic cutting of the trees and then using the wood for their traditional carpentry and vernacular architecture too.

    wud u help me with the kind of trees i shud look for planting and also where cud i find the sun path diagram of leh? what are the major things i shud be careful about while designing?

      How much water will be available at your site and what will be its source? That will decide what can be grown there.
      What will be the temperature at your site? That will be the most important factor for your design.
      By the way, where are you based?

      Dear Aditi,

      I appreciate your problem. Wind directions in the monsoon region are bound to change with season. That is characteristic of monsoon winds. But we cannot design architectural structures that can change with season. However, there are many solutions to your problem.

      If you are designing a large structure like a bungalow or a building, you can have different designs for rooms facing different directions. For example, if you have several bedrooms in a bungalow, people can use different rooms in different seasons and take advantage of the winds in that season. Same applies to office rooms in a huge building, the airconditioning can be optimally designed as per different prevailing wind for different rooms. Not all of them need to be used all through the year.

      The second option is to use the most likely wind direction in the course of the year, which may be westerly or northerly for most of MP. Or use the average for the whole year, that may be northwesterly. Then you can design a structure that suits the average wind. But the overall design performance will always be sub-optimum.

      Please understand that I am a meteorologist and I know little about architecture. This is just commonsense based advice.

        Thank you so much for the information and your opininon. I totally agree with you that India has no place with year-round snowfall and/or power outage due to heavy snowfall. That is why we are looking for places like norway, morgan etc where severe power outage due to heavy snowfall alone occurs, but it is becoming very difficult to avail power outage data from these places. Could you suggest a way to get reliable data of these foreign places.

        Thanks. I am going to close this correspondence with the following comments:
        Even in Europe and America, it does not snow all year round, but only in winter. Accumulated snow is not a cause of power outages. Power gets disrupted only in snowstorms. Otherwise life there remains normal.
        I do not know of sites where power outage data is available online. But Google is always there. “Seek and you will find”, is what Jesus said 2000 years ago. And that is how research is to be done.
        Best wishes, and I wish that you complete your project!

We want the electrical power outage data of a place that experiences snowfall almost round the year. The US countries keep record of power outage, but am not sure about India since we didnt get any informmation in the internet. Could you plz suggest where can we find the power outage statistics of the last few years of any snow clad city of India like Leh, Jammu, or Shimla ? Kindly help.

        Dear Tanaya,
        Thank you for telling me more about you. First I had thought that you were based in the US.
        Although our country has to face many kinds of adverse weather, you must understand that we have more problems not related to the weather. Power outages are so common even when the weather is fine. Severe thunderstorms are the main cause of concern, because of (i) lightning and (ii) squally winds as power lines are damaged by falling trees. Of course there are the occasional tropical cyclones in the coastal belts in which electric poles themselves fall.
        Contrary to what you expect, snowfall does not occur anywhere throughout the year, but only in winter. The accumulated winter snow may however remain in parts of summer.
        The power outage records should be available with the power distribution companies. You may have to visit one of their field offices and collect the data manually. Since you are in Silchar, you could consider going to Darjeeling or Gangtok and do a local investigation.

      Dear Piyush,
      Thanks for your comment. I am a retired person and I do not have any data with me which I can supply to people. For this you should approach the India Meteorological Department. I suggest that you send a mail to IMD at ndc@imdpune.gov giving the details of your data requirements. In your mail to IMD you should specify whether you need hourly, daily or monthly data, whether you need averages or actuals, and also if there is no data for Junagadh which other nearby stations will serve your purpose.

        Dear Swadesh,

        Thanks for sending me your CV. It is quite impressive. Your project addresses very localised issues about Dehra Dun and requires data specific to the region. It may not be available on web sites. I suggest that you get in touch with the Meteorological Centre, Dehra Dun, and the Indian Institute of Remote Sensing, Dehra Dun, for the data that you need. It would be worthwhile for you to visit these institutes, discuss your problem with the scientists there and seek their guidance on using GIS techniques. The vehicle registration figures may be available with the RTO.

    Dear Prof. R. R. Kelkar,

    I am writing in regards to rainfall/surface data and am hoping you can point me towards the right direction.

    I spoke with Dr. Kumar of the IMD Pune Institute in regards to having access to this data at the daily/station level from 1 May to 17 July 2011.
    He kindly explained to me that they only release historical records, not recent records. However, I have seen current data on other websites such as tutiempo.net, but I am concerned about using this data as it is not clear what its source is.

    I have also checked two more websites: http://www.imdaws.com/ (suggest by Ashok Jaswal in a post below), and http://mausam.gov.in/WEBIMD/ClimatologicalAction.do?function=getStationDetails&actionParam=1&param=2&station=Panjim (suggested by you in another post).
    However, I was not able to find the information for this year.

    My question for you:
    1) Would you be able to recommend another site which has reliable rainfall/surface data (ideally supplied by the IMD stations) for 2011?

    I have recently returned from 2 months of work in India and would like to try to match the data I collected with the rainfal/surface data so any suggestions/advice would be much appreciated.

    Kind regards,

    Renata L.

The monthly rainfall data for the years 1901-2000 for 110 stations in India is readily available on the IMD web site at http://www.imd.gov.in/section/nhac/mean/110_new.htm. But if you need more data I suggest that you send a mail to the National Data Centre of IMD at Pune to ndc@imdpune.gov.in. When you write to NDC, you should clarify whether you need district averages or station level data within districts. You may also specify the names of the districts you are interested in or whether you need data for all the districts.

      Climatology and trends in near-surface wind speed over India during 1961-2008
      by A. K. JASWAL and A. L. KOPPAR
      India Meteorological Department, Shivajinagar, Pune – 411 005
      Abstract
      This study analyses near-surface wind speed changes in India during 1961 to 2008. Consisting of monthly wind speed data of 171 stations, the results show that most of the stations in India have experienced significant weakening of wind speed, both at monthly and annual timescales. All-India averaged annual mean wind speed has decreased from 9.7 kmph in 1961 to 5.0 kmph in 2008 resulting in a 49% decline. Averaged rate of decrease in annual mean wind speed is -0.88 kmph/decade. The largest rate of decline is in June (-1.33 kmph per decade) and the smallest is in October (-0.60 kmph per decade). Spatially, large declines are found in western India, south peninsula and the coastal areas while central, southeast and northeast India have the lesser change in wind speed. Significant weakening of wind speed has occurred primarily in regions along Gujarat, Maharashtra, Tamil Nadu, north Karnataka, and coastal Orissa and West Bengal which also have higher annual mean wind speed. Annual mean wind speeds exceeding 15 kmph are observed only over Gujarat and south Tamil Nadu. Some parts of Rajasthan, west Madhya Pradesh, Maharashtra, north Karnataka and adjoining Andhra Pradesh and the coastal belts experience wind speeds of 10-15 kmph. Stations having annual mean wind speed exceeding 10 kmph are rare in northern India.
      The study evaluates climatology of winds and its long-term trends over India where wind power can be profitably utilised. The prominent regions are in Gujarat and adjoining Madhya Pradesh, south Rajasthan, north Maharashtra, north Karnataka, south Tamil Nadu, coastal Andhra Pradesh and along the west coast from Gujarat to Goa and along the east coast from Kolkata to Nagapatinam.

    Hello Sir,

    I am reasearch student of renewable energy systems from university Aachen in germany. Since I am working on a Photovoltaic project in Amaravati District in Maharashtra, searching for meterological data. Basically daily max. Temperature during summer in last years? It would be great if I can track out how many days are above 50 °C during summer in this region? which will make my work bit more precise whether its possible to plan PV project in this region.

    Sir, I am very grateful to you if you can guide me on this matter.

    Thank you.

    Kind regards,

I’m student of environmental architecture studies and currently doing one of the environmental landscape designing project in region called Wada Taluka in Thane District. I’m looking for data related to climate, biodiversity & Eco systems available in this region.

    I visited the websites mentioned in previous blogs but couldn’t find any. Also spoke to officer in Indian Meteorological Department Pune, but found that there is no Thane station covered. In this case, how can I collect the information related to this area.

    Kindly guide me in this regards.

      Dear Prashant,
      I understand your problem, but there is no easy solution. There are so many places in the country where meteorological observatories were not set up because there was no need in the past and so there is no authentic climate record available. The best you can do is interpolate the data between stations around Thane. Rainfall data may be available for Thane proper. Did you check? Also, did you see the “District Gazeteer” for Thane,? It may have some information. You may be able to refer to it in a good library. Otherwise you will have to do some original research like looking through old files or records of hospitals, railways, agricultural and revenue officials, but that is going to be very time consuming and difficult.
      Best of luck anyway,

On what spatial resolution? Are you more concerned about maximum temperature? Or is it daily mean temperature? Are you interested in summer particularly?

    Reply

    • Prof R R Kelkar
      Dec 21, 2010 @ 10:34:35

      Dear Vartika,

      The Aral Sea is located far northwest of the Indian region to affect the monsoon. The shrinking of the Aral Sea, which is really a lake, due to human intervention in the hydrology of the region, started as far back in 1960. There is no evidence of a change in the Indian monsoon rainfall over this period. However, a statistical correlation does exist between the Indian monsoon rainfall and large scale Eurasian snow cover and soil moisture.

      You have not indicated the nature of your interest in the problem. So I suggest that you read the paper “On the relationship between the Indian summer monsoon and river flow in the Aral Sea basin”, by Schiemann et al published in Geophysical Research Letters, 2007, or other similar articles which are available on the internet. You may search for them on Google Scholar.

        Thank u for your response. I’m basically not an expert in subject. The modelling software that we are using is ISC-Aeromod view by lakes Int. Canada. As far as i understood, ceiling height is referred as the height of the cloud base and as per the u.s e.p.a, when opaque cloud cover is less than 5, it can be assumed as unlimited. So i think it is basically the height of the cloud base. Mixing height is a separate parameter and even though it is missing, there are options for estimating it in the soft ware itself

        The height of the cloud base is usually recorded by an instrument called a ceilometer or estimated manually at airports as it is required for aviation purposes. You will have to inquire at the Cochin airport if they have such data and if they can give it you in the format you desire.

    while adding up the monthly rainfall does not equal the annual rainfall mentioned in the data supplied. Its silghtly lesser than the annual rainfall.
    For most of the data it adds up. But only for some the annual rainfall is more than what we get after adding up all the monthly rainfall. Is it O.K?
    If we want to calculate annual rainfall, the value mentioned can be directly taken?or we have to add up all the monthly rainfall?How the annual rainfall is calculated?
    is it just adding up the monthly rainfall?If yes, why iit is different then?

      Dear Sandeep,

      Thank you for visiting my site. Your problem could be due to a variety of reasons, such as rounding off of decimals, quality control of data and so on. You should, really speaking, ask the data supplier about it. But since you have written to me, please tell me what is the order of magnitude of the difference between the annual rainfall and the sum of the monthly rainfall values. If possible, send me the data as an excel or word file and I can ask examine it. Since you are dealing with just one station, the file should be small. My email id is kelkar_rr@yahoo.com. Maybe I can figure out the cause of the discrepancy.

      By the way, do you know Dr R Shankar of Dept of Marine Geology at Mangalore University? He could also guide you in this matter.

      Best wishes in your studies,

      R R Kelkar

    One of my students is asking if the in coming solar radiation is diverted into space by using proper apparatus [mirrors / filters] at a given place will it be possible to reduce the surface air temperature at that place.
    [I am a teacher in a village higher secondary school.]

      Dear Mr Kaneyen,

      Thank you for your comment, which is as you say a question posed by your student.

      Yes, if the incoming solar radiation over a place decreases, the surface air temperature also decreases. That is why higher latitudes are cooler than the tropics. We often experience that when a thick cloud develops in the afternoon, the maximum temperature gets reduced. However, there is a question of scale. Even large reflectors would be very tiny compared to a cloud and would not be of help. Further, the surface air temperature is the result of not just the incoming solar radiation, but also the atmospheric radiation from above and the terrestrial radiation from below. The problem is therefore not that simple. On a very small scale, and where the environment is insulated like a room or a car, sun screens on window glasses do help to keep out the direct heat of the sunshine and lower the temperature.

      If your student has more questions, I will be happy to discuss them.

      Regards,

      Sincerely,

      R R Kelkar

      Dear Dr Sharangpani,

      Your question has two aspects, philosophical and technical. If we could predict our future lives in every detail, by whatever means, we would become God. As human beings, we are subject to many limitations and constraints. At the same time, everyone wants to know the future, although it is not his hands. This is all paradoxical and can be frustrating.

      As far the technical aspect is concerned, there are two types of situations. One in which the weather conditions over a widespread area are very similar. In such a situation it makes sense to say that it will rain over that area, and an individual farmer will benefit from that information because his farm lies within it. But there are times when the weather is not uniform over a region and it could differ from one farm to another. In that case the forecast may come true over some farms but not over others. It becomes more and more difficult to make good weather predictions as the area becomes smaller and the time period becomes longer.

      What I would say is that weather predictions have to be considered along with other information and guidance available, including the farmer’s traditional knowledge and intuition and his deep understanding of local conditions.

      Does this make sense to you? If not, write to me again.

    I am writing from UNEP in Nairobi, and we are doing a publication titled compendium on climate change. We have a report about the effects of climate change in India. We would need a temperature map, showing the temperature extremes, for example showing days when temperature was over 35 degrees celsius. Here’s a link to an example of what we are thinking of: http://climateprogress.org/wp-content/uploads/2009/06/noaa-heat-waves.gif
    And here’s a report about it: http://www.slideshare.net/GlobalChange.gov/globalchangegovus-impacts-summary-1550347?type=presentation

    If you would like more information concerning our project, please do not hesitate to ask.

    Thank you very much for your assistance,

    Marton

      Please visit the site http://www.imd.gov.in. In the middle of the home page, you will find a dialogue box ‘Select station for climatological information’. Here you will get a dropdown list. Choose the station you want.

      The IMD web site provides a lot of other information, some of which may also be of interest to you.

        I am graduate student from Illinois USA. My present research focuses on developing a appropriate rain model for satellite communication in India. Right now we are looking in to a method of obtaining rain height in India. Can you please share any idea that would probably help us to start with. i have pretty good gridded data from NASA TRMM but not appropriate for my purpose. I heard that radiosonde observation will help me get there. Can you please share if there’s any other method to derive rain height and place to get radiosonde observations. Thank you.
