add air density and potential temperature to export state #122
Comments
|
This change would simplify the CICE6 cap, since calculations done in the cap to provide these fields could be removed. @junwang-noaa is it possible to pass these variables from FV3? |
|
@DeniseWorthen We only need these two variables on the lowest model layer, correct? |
|
That is correct. In the CICE cap, we calculate the potential Temperature using the pres_height_lowest and the inst_temp_height_lowest. We calculate air density using pres_height_lowest, specific_humidity_lowest and temperature lowest. So the lowest level pTem and air density at lowest level would be consistent. |

* Removing use of mpp_io_mod and fms_io_mod from the dycore code. Replacing the necessary functions with fms2_io_mod functions
* Adding a call to set_filename_appendix so that nest is added to filename when needed and removing unneccessary code in fv_io_mod
* FV3 Documentation - formatted PDF and source files for FV3 documentation.
* Documentation and defaults changes
- Updated defaults for hord options to use 8 and 10, and removal of mention of hord = 9 (experimental, unsupported) scheme.
* Initialize {sw,se,nw,ne}_corner to .false in model/fv_arrays.F90
(cherry picked from commit bf0630f)
* merge of latest dev work from GFDL Weather and Climate Dynamics Division (NOAA-EMC#114)
* read ak/bk from user specified files (NOAA-EMC#115)
* add input.nml parameter fv_eta_file for user specified ak/bk; change ks calculation when npz_type=input; use newunit to replace fixed file unit for npz_type=input
(cherry picked from commit 3a0d35a)
* FV3 Example Notebooks and cleanup of docs directory (NOAA-EMC#117)
* removed module use of INPUT_STR_LENGTH in fv_control.F90 (NOAA-EMC#122)
* add check on eta levels to ensure their monotonicity
* update Jili Dong's ak/bk external input to
- use the FMS ascii_read (single read/broadcast)
- error check input to ensure the proper number of levels present
* added a format description for the external eta file and ensured a correct the file length check for FMS 2021.03 and greater
* merge of minor updates from GFDL Weather and Climate Dynamics Division (20210804) (NOAA-EMC#127)

When cplflx = true, the air density and potential temperature should be added to the FV3 export state. They should be "height_lowest" values.
These variables are needed by CICE5/CICE6; currently they are being calculated either in the NEMS mediator or in the CICE cap using temp_height_lowest, pres_height_lowest and spec_humid_height_lowest.
