Modelling Solar Radiation in the Arctic an Improved Method for the Subdivision of Global Radiation

Abstract

From an analysis of solar radiation collected at Alert, N.W.T., it was shown previously 2 that existing solar energy models overestimate slope irradiance at low solar angles. In this technical note it is shown that this overestimation results from the breakdown of the relationship between sky condition and atmospheric transmittivity. In particular, at low solar elevations, the portion of the global radiation being attributed to direct radiation at low solar elevations has been developed.
