Abstract

Observations of global radiation received in a small catchment in Yorkshire were analysed for clear sky conditions and an empirical relationship of the form

Q = 1380 sin ΞΈ(a + b sin ΞΈ) W m^βˆ’2^

Found, between incoming solar radiation Q and the solar elevation ΞΈ, where a and b are constants. The constants differ markedly from those obtained in a similar analysis of data from eastern Atlantic weather ships, suggesting that the radiation, under cloudless skies, over inland Britain, is only about 60% of that received under cloudless skies over the eastern Atlantic.
