H. Scheifinger et H. Kromp-kolb, Modelling global radiation in complex terrain: comparing two statistical approaches, AGR FOR MET, 100(2-3), 2000, pp. 127-136
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. (C) 2000 Elsevier Science B.V. All rights reserved
