The current version of the model on this site is RayMan 1.2. I read some presentations about use of the model version called "RayMan Pro". Is it available and where i can find the Pro version and help(manual) for downloading?
The "Pro" Version is a non-public version. Te get the "Pro" Version, please contact Andreas Matzarakis directly. (andreas.matzarakis[at]meteo.uni-freiburg.de)
