Surface Solar Irradiance from ISCCP data

Ocean Biogeochemical Processes Group LBNL

Computation of surface solar irradiance on a global basis. Simply stated, no light => no ocean biology => boring marine geochemistry. We are charged with producing surface solar irradiance fields using combined satellite data from the International Satellite Cloud Climatology Project. Results are temporally resolved every 3 hours and spatially resolved at 0.5x0.5 degrees latitude and longitude for the time period beginning July 1983 onwards. The data will be used to model ocean and terrestiral productivity.
