A simple solar radiation model applicable in numerical hydrodynamical modeling on seasonal time-scale

摘要

A solar radiation climatological data set is used to define a simple radiation model suitable for application in numerical hydrodynamical modeling. The model is based on the ANGSTROM epir- ical relation for albedo of the atmosphere and on a simplified function of sun heoght during the year. The model error is generally smaller than 20/100. The results of the model are discussed in compar- Sion with long time data series for clear sky conditions and actual measurements from the station At the Institute of Oceanography and Fisheries in Split.
