on the basis of the correlation between global radiation measurements and monthly means of surface net radiation flux densities (SNRFD), analysis is done of the correlation of their climatological calculations, confirming roughly their consistency, with a prepared nation-wide chart of annual mean SNRFD with the aid of the regression formula. The pattern agrees fairly well with the results by the residual term of the surface radiation balance expression. Besides, the correlation characteristics are examined between the climatological values of global and the net radiations for slope land, indicating that for the slope <20° their coefficients of the regression equation are in concord with those for a horizontal ground and with the increasing slope the coefficient changes correspondingly.
