Abstract

Records of daily solar radiation energy extending over a period of one year have been compared with readings of sunlight duration obtained with a Campbell‐Stokes recorder. Energy records were made with a bimetallic antinograph. The regression equation obtained for the daily values in Trinidad, West Indies was R = R~A~ (0·20 + 0·59 n/N), with a correlation coefficient of 0·91 where R = radiation actually received

R~A~ = Angot's theoretical amounts of radiation which would reach the earth's surface in the absence of an atmosphere. These values are given by List (1951)

n = actual duration of sunlight

N = theoretical maximum duration of sunlight.
