Hello Bernhard,
look into "Numerische Verfahren zur Erstellung klimatologischer Karten"
from Gerhard Muller-Wohlfeil in "Berichte des Deutschen Wetterdienstes"
No.193, 1995
The described method can be easily redone in Grass.
Hope this helps
Peter

Betreff: Precipitation Estimation
Hello to all.
I have the following problem (or question:)
Does anybody know of any existing tool or module that calculates point
based
precipitation into the surface with respect to the orography?
I used r.surf.idw, but this does only estimate rainfall for a given
surface,
but I need to take orography as well into consideration. How about
r.mapcalc? Did anyone allready made some experience with this sort of
estimation technique?
Cheers
Bernhard Sturm
