GEMCLIM v_3.3.2


GEMCLIM is the climate version of Environment Canada's Global Environmental Multiscale (GEM) model.
GEMCLIM version 3.3.2 is using RPN dynamic version 3.3.2 and RPN physics version 5.0.4.

If you are a new user of GEM you might first want to read the general introduction to GEMDM.

General help and support about models, libraries, tools and many other interesting information you can also find at RPN.COMM: Community for Mesoscale Modeling.
