Amethod(Rieland,1985)hasbeenmodifiedtodeterminethedownwardsolarradiationatgroundoverEastAsia,usingGMS-3dataofthesatellitewithaspatialresolutionof10×10krn~2andatimeintervalof3hours.ThedistributionsofthemonthlymeanglobalradiationareobtainedforJanuary,April,JulyandOctoberof1985.TheseresultsillustratethatthetopographyeffectoftheTibetanPlateauisnotnegligible.ThevaluesofglobalradiationoverthehighTibetanPlateauduringallseasonsarehigherthanthoseinthelower-levelsurroundings.Bycomparingmodelresultswithgroundobserveddata,therelativeerrorsinmonthlyaveragesofglobalradiationare2.8％forclearskyand6.3％,5.3％,5.0％and4.5％forcloudyskyinJanuary,April,JulyandOctober,respectively.Therelativeerrorindailyglobalradiationduringthesnow-freeseasonislessthan20％andlargerthan20％insnow-coveredwinter.We,however,hadnodataforthesecomparisonswhichweremeasureddirectlyatthePlateauduringtheyear1985.
