You can download weather data files that contain information like  
direct normal,
diffuse and global horizontal radiation in Wh/m^2 here:

http://apps1.eere.energy.gov/buildings/energyplus/cfm/weather_data.cfm

This data is for the EnergyPlus program. You can download the 'stat'  
files
which are readable text files with average values for wetware  
('brain') processing.

There is also the Satel-Light website but I don't think it covers  
areas outside of Europe:
