Met Data 2004-2008

In response to an RTI petition by the South Asia Network on Dams, Rivers and People (www.sandrp.in), the Indian Meteorological Department (IMD) has made rainfall data for the past few years available at a monthly level, for each district of the country on their website: IMD .

India Water Portal has imported all the data from 2004-2008 into a spreadsheet that you can download and save for future use.

Please note that IMD has updated their website with partial 2009 data too; this data will be incorporated into the IWP spreadsheet on this page at a later date.

Thanks to Sailendra Mishra for helping with the import of the data into the spreadsheet, and R.N.Divakar for checking the data. 

While India Water Portal has taken significant effort to make sure of the validity of the data, we are not responsible for any errors that may have occured.

8. Climate data

Submitted by PRATIBHA (not verified) on December 27, 2011 - 11:12.

Respected Sir/ Ma'am,

1. Please let me know how I can get the station wise meteorological data on a daily basis, specially rainfall and temperature.

2. Can you please provide me the meteorological stations location and no. of stations in Dikhow catchment, Kopoli catchment and Pagaladiya catchment (tributaries of Brahmaputra river).

3. I downloaded some met data from your website but it is on district basis, so could you pleas tell me how you came to an average with the data available and made it at district  level and how many stations you used for averaging.

I am in urgent need of meteorological data (station wise) on daily basis, at least for 30 years. Please help me.

7. Request For rainfall and temperature data

Submitted by Amita Sharma (not verified) on December 14, 2011 - 14:54.

Hello,

How can I get 20 year district or taluka level data from 1991-2010 for rainfall and temperature for Gujarat State?

6. Max daily rainfall over a 24 hour period and no. of rainy days

Submitted by Shubha (not verified) on March 23, 2011 - 23:31.

Would it be possible to get the following

1. Max rainfall in a year over a 24 hour period for each of the districts

2. No of rainy days in a month.

If this info. could be available at Taluk level it would be still more helpful.

5. 2003 data gap

Submitted by anup saikia on April 15, 2010 - 15:06.
I wonder if the data gap for the year 2003 can be filled in.... because data prior to 2002 is available as is 2--4-2008. However 2003 data isn't available and this hinders a time series analysis of climate variables. please help!!

Good effort, but there is a catch. We discussed this when we finalized the HIN survey report. What if someone takes data from our site (if and when); re-packages it in the hope of improving it; and in the process makes some error. We have battled similar problem earlier – In the era of IBM-360, a lot of hydraulics and hydrology software came from USA as FORTRAN source code. Over the years people tried to "improve" it, and spwaned so many copies of this source code and now it takes a phenominal effort of comparing it with a print line-by-line, to say which is the correct code. Finally we concluded there is no way to stop this, and a person who uses re-packaged data has to accept the same risks as a person who downloads a .exe file from an unknown source. But if you have a way of assuring data integrity, I am interested. Chetan Pandit

Good to know of the data availability at the district level. Do you know whether there is data available for the mandals from the same source. If we are looking at local area then information at the mandal level will be very useful. How is the data collected from each of the raingauge station in different locations all over the country handled who will have the data finally. How well organised is it. Is there a system to access the data at the raingauge station level. i have been wanting to collect the data for our taluka in Mysore district where our farm is located for the last 40 years, considering that u are not located locally is a source which one can access and get the information. regards Dinesh

2. Comment from Dr. Himanshu Thakkar

Himanshu Thakkar of SANDRP, www.sandrp.in (the organisation that filed the original RTI), commented to us:

======

Thanks, this is indeed useful. Two quick suggestions:

1. It may be useful to add a column at the end to give total rainfall for that year.
2. It may be useful to add the NORMAL rainfall row for each district?

1. Comment from Dr. Ramachandra Reddy

Submitted by vijay on September 30, 2009 - 14:00.

Dr. Ramachandra Reddy forwarded this comment to IWP:

Dear Sirs,
Thank you for a valuable information.Even a cursory glance at the details gives the following information:
1) No defined pattern is evident that can help irrigation practices to be implemented properly by planning  in advance.
2) Monthly rainfall pattern indicates good rainfall in a month preceded and followed by poor activity.
3) 2008 has shown , especially in different parts of Andhra Pradesh, that monsoon vagaries can adversely affect irrigation practices in chronically drought hit segments of the state.The farming community, basically comprising of non technical personnel, has not noticed this change leading to significant losses during 2009 kharif season.A close observation of the data clearly shows that the duration and pattern of both southwest and north east monsoons have significantly changed in the recent times, affecting even such tracts in the coastal belt that are known to receive good quantities of rain.
4) It may be worth correlating the monsoon pattern with the fluctuations in the surface temperatures and global activities, like forest fires/ volcanic eruptions/large scale deforestation/emergence of Elnino and Lanino/ frequency and pattern of storm surges. 
4) Even though no one can come out with a standard design characteristics, it is now evident that we need to have area specific designs to properly establish micro level storage facilities to store rain waters as and when they are available .
Congratulations for an efficient input.
Regards
P.R.Reddy
