Introduction

Over the next few years, the plan is to merge standalone MESH and MEC-MESH. This involves getting standalone MESH users up-to-speed with running MEC-MESH as well as taking the best parts of standalone MESH and developing those features and processes into MEC-MESH. This wiki page is meant to maintain "living" documentation to assist in the transition of standalone MESH and MEC-MESH. If you see parts of this documentation that need improving, and if you have write privledges on this wiki, please feel free to make the necessary improvements or point out where improvements are needed.

What is the difference between MEC-MESH and standalone MESH?

The main difference between the two versions of MESH is the surrounding code to the model physics, sometimes refered to as the drivers and sequencers. However, there is some difference in the physics between the models and the first task will be to close the gap so that MEC/MESH has the latest physics that is currently in standalone MESH. It is important to note that MEC/MESH currently uses the GEM 3 atmospheric model, which is being upgraded to GEM 4 by the Canadian Meteorological Centre (CMC) of Environment Canada in Montreal. The Hydrometeorology and Arctic Lab (HAL) in Saskatoon and Edmonton will be involved in planning the migration of MESH from GEM 3 to GEM 4, but the actual development of MESH in GEM 4 won't likely start until 2012. This is an important point for collaborators outside of Environment Canada because we can only support the use of standalone MESH for non-EC collaborators until MESH has been built into GEM 4.

The following links provide more detailed information about MEC/MESH for the standalone MESH community.
