GFS ozphys Main

The operational GFS currently parameterizes ozone production and destruction based on monthly mean coefficients (global_o3prdlos.f77) provided by Naval Research Laboratory through CHEM2D chemistry model ([61]). More...

  • Calculate vertical integrated column ozone values.
  • Apply vertically linear interpolation to the ozone coefficients.
  • Calculate the 4 terms of prognostic ozone change during time dt:
    • ozp(:,:,1) - Ozone production at model layers
    • ozp(:,:,2) - Ozone tendency at model layers
    • ozp(:,:,3) - Ozone production from temperature term at model layers
    • ozp(:,:,4) - Ozone production from column ozone term at model layers
