Abstract : Two schemes for estimating the amount of solar radiation received at the earth's surface are compared to solar radiation measurements. This data was acquired over a total of 25 days and from 214 individual observations. These observations were grouped into both instantaneous and hourly averaged data. Of the two schemes studied, the insolation parameter Psi performed better than the net radiation index used in the Pasquill-Turner Stability Category algorithm. To eliminate the need to subjectively estimate the amount of solar radiation, an algorithm is presented to determine a continuous Pasquill Stability Parameter based on direct measurement of solar radiation. This algorithm compares favorably to one previously developed by Great Britain's meteorological office.
