Abstract
Two simple approaches for assessing global radiation in complex terrain are tested and compared. A parameterisation scheme for global radiation based on cloud cover observations was compared with interpolation of measured glo bal radiation values from the Austrian climate observation network. Interpo lation appears to be a useful method for a station density which has been a vailable after 1992 in Austria (about 1000 km(2)/station). In that ease int erpolation is superior to parameterisation. The quality of interpolated dat a quickly drops with height and for elevations above 1500 m neither method delivers useful results.
