Incomplete MCIP outputs


#1

The GRIDCRO3D file is not generated by MCIP. What may be the cause?


#2

GRIDCRO3D is only created when MCIP is used to process MM5 data. The fields in GRIDCRO3D are X3HT0F and X3HT0M, which are the heights on full levels and mid-levels; they are static in time with MM5. In WRF, however, the layer heights change with time. The time-varying layer heights are stored in the METCRO3D arrays ZF and ZH.


#3

This information is very helpful, thank you. Is it a good practice then to replace GRIDCRO3D by METCRO3D in CCTM simulations? I am guessing that CGRID is generated by CCTM when one of these two files is provided.


#4

CMAQ is already configured to get what it needs from METCRO3D. If you are running with WRF, CMAQ is not expecting you to have a GRIDCRO3D file.
