u can download rainfall from TRMM and temperature from ERA Interim

Hello, You can download the precipitation data of india from TRMM, follow the link below:

Dear Akinsanola

Can you please send me the link to download the temperature data.

Hi Vikram.

You can try the following link if you require point data at nearby locations.

Vikram, if the study area and time period are small, I suggest you to get station data rather than interpolated IMD or TRMM data. Please let me know your study area and if possible please give me a shape files for the area. I may have some data that would help you

Hey Sandeep ....

Thanks for your suggestion, I will email you for the shape file.

Yes, Vikram,

It is always good to use primary data (Station data) if we have. Satellite, reanalysis data are not good as station data. Though, in case of no data, we can use those data, which are better than non.

Thank you,

@ Mohan: Thanks

I do understand the importance of primary data but for modeling sometime we have to arrange secondary data.

I have my station but I am in need of past data of nearby area.

You may get this data at I

National Data Centre of India Meteorological Department, Pune.

Dear Vikram,

you may have a look at my following papers which include references for data for a catchment in Maharashtra:
