RELEASE_NOTES for CMAQv5.0.1 - July 2012
The changes for this release are:
AQCHEM (base and MP version)
Fixed bug where negative oxidized Fe and Mn concentrations resulted in negative oxidation time steps, which caused the estimated wet deposition factor, WETFAC to blow up
The washout rate was removed from the calculation of the estimate for doubling the time step if the sulfur oxidized is < 5%.
NML & runscripts (CCTM, ICON, BCON)
Changed the environment variable name for the CGRID species Namelist files from an embedded '.' to '_'.
ICON
Moved mapping_init.F from par module to m3conc module where it belongs
Inline BEIS
Bounded COSZEN against numerical rounding errors
Made Pleim-Xiu version the default method for soil data in soil NO subroutine
Inline Plume Rise (point source emissions)
Fixed the number of substeps, NTICS to be the number of synchronization time steps rather than the number of seconds in the calculation of the average plume rise emissions for the diagnostic file.
M3DRY
fixed errors in crop_lai
Soil NH3 initialization was rewritten for new daily EPIC output which now includes soil NH3 from mineralization of organic but no longer includes the monthly fertilizer totals
Set bounds on the soil pH for fertilized AG landuse
corrected soil NH4 and H+ initialization error
Advection
changed default HDIV_LIM to 0.9; made CFL an env var
BLDMAKE utility
