I wish to create a longterm time series over the land surface such as global river basins.
If your application is in India, you can use the free NREL database, which is certainly better and at higher resolution than NASA SSE. It provides global irradiance data--not net radiation though.

For sunshine, you would need to search the WRDC database for a nearby station.

You can go to HOMER's home page and will get direction on how to get solar radiation from NASA's website. You can specify the latitude and longitude and get archived data of Total Global Solar Radiation
You can get the weather data files in the following link-

US department of Energy database
If you want to create a data for a specific location, best way is to take measurements. Typical Meteorological Year (TMY) data is obtained from these measurements. For certain locations, TMY data is available and released in NREL's website. (http://rredc.nrel.gov/solar/old_data/nsrdb/1991-2005/tmy3/)
If there is no available data, you can create a data using Meteonorm software. As well as I know the software uses the existent TMY data and principles of solar energy utilization theory .

hi, you can get it from NASA SSE web site for any location using Longitude and latitude. its with 1*1 degree grid data from 1983 to 2005. this is satellite data and you can have measured data from some other sites.
the best satellite data is ERA-interim data which you download for any location but you have to analyze it for the selected location.
if you want to use data with any simulation program you have to get is from Meteonorm.

Hi, you can find these data in several Softwares, namely Homer or PVSyst
Data set is available from
NASA : https://eosweb.larc.nasa.gov/cgi-bin/sse/[email protected]+s01#s01
or http://power.larc.nasa.gov/
otherwise from Meteonorm : http://www.meteonorm.com/
NIWE: http://niwe.res.in/department_srra.php
HOMER software can be used for NASA data.
Marcin:
Note that the DOE database, which has recently moved to this new site: https://energyplus.net/weather
This provides consttructed TMY data files, not real observations. So this might not be what you need...
you can get from lot of source...particularly y can get data from MNRE website
You might also check IRENA Global Atlas http://irena.masdar.ac.ae/ and Meteonorm a woldwide database for relatively small money http://www.meteonorm.com/en/
And not forget SolarGIS / GeoModel http://geomodelsolar.eu/ a bit more expensive but very good data.
Good luck
You could use the following:

you can use the Meteonorm program follows this link http://www.meteonorm.com
