India Weather Data

My blog statistics have revealed that many viewers have reached my site in search of weather 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 then click on the locator map on the home page. For each station, observations of maximum temperature, minimum temperature and 24-hour rainfall, departures from normal, times of sunrise, sunset, moonrise and moonset, and the local forecast, would be displayed. The IMD web site offers online plenty of information of climatological as well as current interest.

        An instrument used by companies to hedge against the risk of weather-related losses. The investor who sells a weather derivative agrees to bear this risk for a premium. If nothing happens, the investor makes a profit. However, if the weather turns bad, then the company who buys the derivative claims the agreed amount.

    Is there a correlation between presence of windmills and the precipitation levels in that area? There are some reports from Texas and China which state that the rainfall decreases in the downwind areas. On my recent visit to Udumalpet in TN ,which has significant windmill deployment, the locals were mentioning lesser rainfall. Has anyone done this research in India? Where can we get the data for a period of 10 years to do studies in all areas having significant windmill deployment?

        Dear Sreedharan,
        Thanks for the clarification.
        There was a similar scare when windmills were installed in south Maharashtra a decade back. But a scientific study was carried out and it dispelled all doubts. I do not have a copy of the report.
        So I feel that you need not worry. You could still carry out your own independent study but that will be like reinventing the wheel.

      Wind roses for some stations in India are available online at http://www.imdagrimet.gov.in/search/node/wind%20rose
      However, IMD is the only source of long term data on winds. So please contact them. Mangalore has an airport, so you should be able to get the wind rose for Mangalore at least. See this site http://www.windfinder.com/windstats/windstatistic_mangalore_bajpe_airport.htm

    Respected Sir,

    I want to collect cloud cover data for Kharagpur, West Bengal, India. Different websites like World Weather Online, Intellicast and Weather 2 provide different figures for the same hour and date. I do not know which one to follow. As far as my understanding goes these data are modelled and not actual observations. Am I correct? Could you please suggest me some guideline about it? Also, if I were to collect it myself, what method can I follow? Can I analyse sky photographs and do it on my own?
    Thanking you for your kind advise

      Dear Aparna,
      The problem is that extracting cloud cover information from satellite images is difficult. Because the satellite sees clouds from above, which is the opposite of an observer’s viewpoint. The same is the problem with cloud data extracted from models.
      So what you really need is actual observations of the sky made by an observer. The cloud amount in oktas, the type of cloud, the height of the base, can only be recorded by an observer looking skyward.
      Since you are at IITKGP, please find out if any of your departments has already collected such data. If not, then discuss your data needs with IMD’s Regional Meteorological Centre at Alipore, Kolkata.
      It is also important for you to decide with what accuracy you need the data. That will make your search easy.
      Best wishes,

        i am interested in studying continuous long term variability of cloud cover data over Lakshadweep sea and for that i am not sure whether I can use the ground station data available from Minicoy island alone to detail the cloud coverage for entire Lakshadweep sea.
        Sir, Regarding the Satellite imagery, I have tried with MODIS cloud fraction data and was not satisfactory because of its coarse spatial resolution. in this regard, i request you to provide me a data source to obtain quality satellite images.

        You have defined your problem quite vaguely. When you say MODIS is ‘coarse’ resolution, what is the resolution that you are going to work with? And when you say ‘long term’ how many years of satellite data would you need? And what is a ‘quality’ satellite image? If you don’t like MODIS you can use Kalpana data, for which you will have to ask IMD.

    The Konkan Strip has been heating up for the past few days, Ratnagiri recording in the range of 38-39 degrees, Mumbai( S.crz) have touched 40 degrees today. On contrary interior regions like Madhya Maharashtra, Vidarbha have been near about normal( 33-36 range). Clearly the sea breeze( which brings a cooling effect with added humidity) in konkan is simply not setting in in-time, i.e. by late afternoon and temperatures are shooting up like anything. Any reason for this abnormal phenomenon? Is the dry North Easterly land breeze too strong over Konkan or anything else?

    Thank you for your reply Sir, Btw I am a weather enthusiast and in no way related to the world of meteorology either academically or professionally. I have keenly followed the vagaries of weather for long especially over the sub-continent and weather phenomenons excite me a lot. I have another query regarding the frequency of Western Disturbances during winters. I have observed that this year WDs have been quiet frequent and strong enough to affect not only NW India but the entire stretch of Indo Gangetic plains, MP, Gujarat, Chattisgarh and Orissa. Is there any particular global phenomenon behind this and if this trend continues should there be a change in cropping patterns( for your information untimely rains/hailstorms on 11th Feb in North Maharashtra and South MP have caused widespread damage to crops).

      Dear Arindam,
      Data recorded at two different sites will never be identical. But you can substitute one for the other depending on your application, which you have not revealed to me. Rainfall is highly variable with regard to space and time, but temperature and wind do not differ much if the topography is the same. So you can decide accordingly.

    Dear Prof Kelkar, we wish to install a Tethered Helium Passenger Balloon at Mussoorie, Uttarakhand. Our Balloon carries upto 20 passengers upto a height of 300 feet & can fly safely till a speed of 22 knots beyond which we need to Moor it. Since the viability of this project depends on wind speeds, i require historical data for this Hill station for the past 12 months. Appreciate if you would guide me. Thanks

    Dear Sir,

    Greetings.

    I am Surendhiran (Final year B.E. EEE) from Coimbatore Institute of Technology. As a part our project we are developing mathematical models for calculating solar irradiance for major cities in TamilNadu. As you may be aware of, last week Tamilnadu Government has announced its “Solar energy policy” in which there are solar irradiance data for each location in Tamilnadu based on the NASA climatic data collected during 2002-2008 (hour by hour). As per that data, Coimbatore has average global solar radiation of 5.290 kWhr/m2/day (455.17 calories/m2/day). But as per the data we collected from TamilNadu Agriculture University’s agroclimatic centre for the year 2008-2012, the average solar radiation of Coimbatore was around 4.31 kWhr/m2/day (385.177 calories/m2/day). Despite the difference in the timings of recording, these data seems to be deviating significantly from each other. Here I request you to comment on this issue because your view will be helpful in our modelling. I would like to know which data is likely to be more accurate.

      The best way of doing this type of research is by working in the fields. But these days researchers prefer to sit on a computer and expect all the data to be displayed on their screens. This is possible with meteorological data but agriculltural data bases are not as well-organised. So you will experience difficulty.

        Sir there is one more request for you,I want want to remind you that my research is both analytical and based on the historical data ,we are going to predict the crop production for a particular region with the help of the historical data related to the the crop production (MAIN FACTOR) and the factors which may affect the crop during any season ,for example temperature,humidity ,rainfall,soil fertility for that region .So sir I need the information from where to get the data (specially the soil fertility and the crop production data ).
        Sir also suggest me from where to get the information that how the factors mentioned above affect the crop production simultaneously ,as we have to generate the rules out of this information that how and how much the factors affect the production.For example we can generate the rule like this: IF the temperature=normal and humidity is normal,rainfall= average THEN production=good.Please provide me any source(any link or research paper”how temperature affect the crop production ” and “how the humidity affect the production and “upto what extend the rainfall is usefull for the crop production(wheat and bajra) “) to get necessary information to create the knowledge base for the rule generation step.

    Dear Sir,
    Thanks for spending me your valuable time. I am terribly sorry if this comment comes twice because I had some problem with my connectivity and I not sure that my previous comment was posted or not(hence I repeat this again). Wind direction is not my concern as turbine head is dynamic to changes in wind direction. I think I may need to clarify my first query. The data for wind speed I have, was taken at 8.30amevery day and it is the average wind speed for the whole day. But average wind speed for the whole day(average dinural wind speed) is what I need. Is there anyway to calculate the average wind speed with the data I have?

      Aug 26, 2012 @ 12:38:07

      Dear Surendhiran,
      Of all weather parameters, wind speed is the most variable. So, it cannot be extrapolated or interpolated. If you really want average for the day then you will need several observations over the 24 hour period and then take their mean.
      If you want averages directly you may see this link

      http://www.tutiempo.net/en/Climate/Coimbatore_Peelamedu/2011/433210.htm

      Here you will get wind data on daily, monthly and annual scales for Coimbatore, but I am not sure about the site’s authenticity.

I am doing my project on solar and wind energy hybrid systems. I have wind speed data taken at 8.30 am for every day for the past 4 years. Now I have to calculate the mean wind speed of coimbatore throughtout the year so that I can optimise my wind turbine design. I want to know is there any empirical formula for the calculation for mean wind speed from the data I have or there is any website which provides accurate mean speed data

    • Prof R R Kelkar
      Aug 25, 2012 @ 00:22:45

      Dear Surendhiran,
      Wind is a vector quantity, so if you have both wind speed and direction data, you should derive a vector mean. This is done by breaking every wind value into a u- and v-component, i.e. easterly and westerly component, then averaging the u- and v-components and finally combining back the average u- and v-components back to the average wind vector.
      However, if you have only wind speed data, or if you are not interested in wind direction, then you can just average it over the 4 year period and get an arithmetic mean of wind speed.

    Dear Prof. Kelkar

    I am a Research Fellow in SAC-ISRO. My research requires the ‘Windrose diagrams’ for the metro cities (especially for Dehi, Mumbai, Kolkata, Chennai, Bangalore, Hyderabad, and Ahmedabad ) to find the downwind regions of the cities. Can you please provide me some information about ‘from where I can get the data?’

    Also I have a doubt regarding air quality data availability from IMD. For how long period it is available and what is the nature of data?

    Kindly help me.

    Thanks in advance.

    (PS: This blog is really useful for researchers. Some of the previous posts really helped me to find some required data sources. I am grateful to you for that. Thank You Very Much..)

      Dear Arya,
      Thank you for visiting my site and for your words of appreciation.
      Well, frankly speaking, since you are in SAC, you should directly approach IMD for all your data needs, since IMD and ISRO have such excellent institutional relationships.
      Have you met the Director of Meteorological Centre, Ahmedabad, or talked to her about your requirements? I am sure she would help you.

    Sir,

    This is Kousik from west bengal,India.From Last few days I am searching for some graphic data showing 24 hrs of temperature variation in graph starting from 00 hrs to 24 hrs for the most hottest day and place for India for the year 2012.I get some data from IMD as well as other sites but they don’t fulfill my requirement and I am now puzzled how I continue my R&D because this is the assingnment given to me by my Project Manager,basically this data is required to made a prototype(TRACTION CONVERTER UNIT FOR INDIAN RAILWAYS LOCOMOTIVES) and this data specifies the maximum operational temperature during day time in India for the locomotive.

    Hope I will get the reply and the much needed help from your side.

    Thanking You,

      Dear Kousik,
      The best way to overcome your difficulty is to simulate a diurnal temperature graph. The maximum temperature is usually observed around 1430 hours and the minimum around 0730 hours local time. Using an extreme value of say 50 deg C for the maximum and a minimum of say 20 deg C you can yourself construct a smooth diurnal curve.

However, much depends on what you want to do with them. If it is just your hobby, you can go ahead, but do not expect accurate data from such makeshift tools.

      Well, you cannot construct a wind rose if there is no wind data! But you have the following options:
      (1) Instead of Ooty you can choose another station (for your case study) for which data is available
      (2) Get data for stations around Ooty and interpolate
      (3) Get data for a neighbouring station and use it for Ooty with some approximations

        I retired from IMD eight years ago and do not speak for it. But it is really impossible to put all meteorological data for a country of India’s size on a web site as the volumes are prohibitively large. However, if data is not on a web site, it does not mean that it is not available. I suggest that you get in touch with IMD at an appropriate official level.

    I have been trying to find hourly wind speed data for Madhya Pradesh to match the hourly wind resource with the hourly load demand, but am limited by budget constraints.

    Would you be able to suggest any sources I could get this data for free or at the lowest cost?

    So far, the Jamgodrani wind farm offered the hourly wind speed data for 2006 @ 500USD, IMD seems to be offering it @ 565USD by my own calculations, and http://www.cwet.tn.nic.in/html/departments_ps.html is offering @ 316.6USD.

      Please visit the IMD web site at http://www.imd.gov.in/section/climate/climatescroll.htm for Delhi data.

      Satellite retrievals are not directly comparable with measurements made on ground, primarily because the surface emissivity is not precisely known, unlike over the sea where it can be assumed to be 100 %.

        Dear Sir,

        Thanks a lot for the help.

        I visited the link you provided. But that gives me only one number for the max, min, etc of temperature between 1971 and 2010 for New Delhi. I need the max, min, averages,etc temperature records for each of the 366 days in 2008.

        Is that kind of record available online?

        Dear Sir,

        I’ve been looking for snow precipitation data for Indian cities/districts for any one year, without much success. The IMD website and most other portals give rainfall stats. But I cant find snowfall data anywhere on the web.

        The final purpose is to know which districts in India are permanently snow-covered or at least have a snow cover for most of the year.

        Thanks,

        Sir,

        I’m working on a paper relating satellite observed data with economic activity, like I mentioned before. Its been observed that snow-covered areas reflect more light which is captured in the satellite images, and hence need to be corrected for, before any economic estimations can be done.
        I’m getting good results for the rest of India, except for the north-eastern states and mountain states of India. Therefore, I need to investigate if it is the effect of snow that is leading to these errors.

      Dear Asis,

      I suggest that you visit the Regional Meteorological Centre, IMD, Alipore, Kolkata, and discuss your problem with the scientists there, if it is possible for you to do so. The India Meteorological Department, Pune, has very recently brought out a publication entitled “Solar Radiant Energy over India” (876 pp.). You may like to acquire it for yourself or consult it in the IMD Alipore library. It may contain the information that you are looking for.

      I do not think that it is a good idea to try to derive bright sunshine hours from temperature as the relationship between them is not straightforward. Sunshine is more a function of cloudiness than temperature.

      Wishing you good luck in your project,

      Sincerely,

      The India Meteorological Department is the official agency that provides meteorological data to users like you. However, mostly current data is available online. I suggest that you send an email to National Data Centre, IMD, Pune at ndc@imdpune.gov.in and let them know about what exactly you would like to have. I am sure that they would be able to help.

      Regards and best of luck for your endeavour,

    Dear Dr Chatterjee,

    If you are interested in rainfall data alone, then I recommend the site Monsoon On Line which you can visit through the IITM web site http://www.iitm.ernet.in.
