Description
The current CCPP ozone parametrization, based on McCormack et al. (2006), does not handle the Antarctic ozone hole, as noted in that paper. This PR uses ozone loss profiles from Hassler et al. (2011, JGR-A) to update the climatological or reference ozone net production term in the parameter files, with tweaks for better agreement with GDAS column ozone values.
This PR requires a new file in
FIXgfs/am
orHOMEgfs/fix/am
, that file being available in modify-ozone-production-loss.zip as "new-params/ozprdlos_2015_new_sbuvO3_tclm15_nuchem_shozhvlogp.f77", together with the program to modify the existing file, in "new-params/daylight_hours.f90" and "new-params/modify_ozprdloss_file.f90"These files are available on Hera at
/scratch1/NCEPDEV/global/Daniel.Wesloh/global-workflow-20250128/new-params/ozprdlos_2015_new_sbuvO3_tclm15_nuchem_shozhvlogp.f77
