General information
GEM is Environment Canada and Climate Canada's Global Environmental Multiscale (GEM) weather and seasonal forecast model. Most of the source code is written in Fortran. Just a few basic routines are written in C. The call of the executable is surrounded by pre- and post-processing shell and Python scripts. A hand full of configuration scripts allow the user to set basic parameters.
At the ESCER Centre of UQAM we take a copy of GEM and modify the code and scripts to convert the weather and seasonal forecast model into a climate model. The main differences between GEM and GEM-UQAM are:
...
"Developmental version of CRCM5/GEM3, CRCM6/GEM5"
"MRCC5/GEM3, MRCC6/GEM5 en développement"
Grids
GEM5 supports rotated lat-lon grids:
- global uniform
- global YinYang (two LAM grids, each covering a little more than half the globe, overlapping like a tennis ball)
- regional LAM (Limited Area Model) grids
