GFS Ozone Photochemistry (2015) Scheme Module

The operational GFS currently parameterizes ozone production and destruction based on monthly mean coefficients ( ozprdlos_2015_new_sbuvO3_tclm15_nuchem.f77) provided by Naval Research Laboratory through CHEM2D chemistry model (McCormack et al. (2006) [120]). More...

GFS ozphys_2015_run General Algorithm

• This code assumes that both prsl and po3 are from bottom to top as are all other variables.
• This code is specifically for NRL parameterization and climatological T and O3 are in location 5 and 6 of prdout array
