GEOS-5 Meteorological Fields
GEOS-5 and MERRA meteorological fields have been processed for use with MOZART-4 (and MOZART-3 and CAM-chem) and are available on the Earth System Grid (earthsystemgrid.org). These files are available at 0.5x0.5 degree and 1.9x2.5 degree resolutions. These files have 72 levels, but only 56 levels are needed for running MOZART-4. In the preprocessor input file specify, under "Spatial Dimensions" (for 1.9x2.5):
Longitude points = 144
Latitude points = 96
Vertical points = 56
This will automatically use the lowest 56 levels of the met fields. Then rerun the preprocessor and build a new version of the model using the new preprocessor output.
In the namelist file:
1) modify the dyn_flsp%nl_filename, dyn_flnm_prefix, etc. values to point to the GEOS5 files
2) remove the parameters oronm, phisnm, shflxnm, and qflxsc, as the GEOS5 files have these variables with the expected names and units
