Coupling with WRF-Chem
As of WRF 3.4, WRF-Chem is now included in the SFire repository. Work into coupling SFire with WRF-Chem is ongoing. See branch chem. As of April 21, 2012, a working template has been implemented to inject a tracer into the atmosphere. This implementation seems to work as expected.
Compiling with chem support
Compiling the code with support for WRF-Chem is similar to the standard procedure. You must set an environment variable WRF_CHEM and configure with the argument chem as follows.
export WRF_CHEM=1 ./configure chem ./compile em_fire
