Re: [EnergyPlus_Support] Solar radiation measurement

preEN ISO 15927-1:2002(E) Annex A provides 
guidelines for splitting global irradiance into 
components of direct and diffuse 
irradiance.  There are additional algorithms 
described by Duffie and Beckman in their Solar 
Engineering of Thermal Processes book.  These may help you.
