Welcome to WRF-GC!
WRF-GC (WRF coupled with GEOS-Chem chemistry) is an online coupled model based on the regional meteorology model, WRF (Weather Research and Forecasting Model), and the GEOS-Chem chemical transport model.
This is the new web-based WRF-GC documentation. We are actively working on adding content.
Check out the WRF-GC website at the Atmospheric Chemistry and Climate Group at SUSTech.
This documentation is under active development. Some content may still be under the old documentation, with step-to-step instructions, in this PDF.
