Ozone Sources and Sinks

Detailed Description

• Current operational version based on Naval Research Laboratory's CHEM2D model (McCormack et al. 2006 [42])
• Monthly and zonal mean ozone production rate and ozone destruction rate per unit ozone mixing ratio were provided by NRL based on CHEM2D model
• Original version of these terms were provided by NASA/DAO based on NASA 2D Chemistry model
• GSM is capable of running both versions

Intraphysics Cummunication

• Routine OZPHYS is called from GBPHYS after call to RAYLEIGH_DAMP
