Description (last modified by )
Added coupled of enhancements:
- Added the capability to write surface air temperature (Tair) to history, quicksave and average, output NetCDF files. Sometimes it is advantageous to write out the air temperature used in the net surface heat fluxes when BULK_FLUX or atmospheric coupling is activated.
The standard input script roms.in includes:
... Hout(idTair) == F ! Tair surface air temperature ... Qout(idTair) == F ! Tair surface air temperature ... Aout(idTair) == F ! Tair surface air temperatureWarning: All the ROMS standard input files were modified to include the logical switches to write out surface air temperature including the one on the test repository.
Code was added to the output routines def_avg.F, wrt_avg.F, wrt_his.F, and wrt_quick.F. The files def_his.F and def_quick.F already have the definitions for adding Tair.
- Modified diag.F and close_io.F to provide more information when ROMS blows-up. The blowup_string in diag.F stores the reason why the model is blowing-up. For example, we can get:
Blowing-up: Saving latest model state into RESTART file REASON: MaxDensity = 9.1E+03
- Updated ESMF coupling input script coupling_esmf.in to include the nested grid number (NestedGrid keyword) when merging field from DATA and ESM components.
! Weighted coefficients for the merging of DATA component fields with the same ! field from other ESM components. Melding coefficients are positive and MUST ! add to unity. They are read from an input NetCDF file ('WeightsFile'). The ! user needs to specify the NetCDF variable names for the weights for the DATA ! ('VnameDATA') and ESM ('VnameESM') components. Also, specify which grid ! ('NestedGrid') needs a merged field from DATA and ESM components. Currently, ! the weight values are only needed by the atmosphere component. WeightsFile(atmos) = meld_weights_atm.nc VnameDATA(atmos) = data_weight VnameESM(atmos) = ocean_weight NestedGrid(atmos) = 1
It is possible to couple directly with one of the nested grids only, for example:
Here, the red box is the regional ROMS grid, while the black domains are the atmospheric coarser (45km) and finer nest (15km) grids. The coupling between the ROMS and the atmospheric model can be done with either the coarser grid (NestedGrid(atmos)=1) or the refined grid (NestedGrid(atmos)=2). The DATA component is used to provide SST in grid cells not covered by ROMS. The weighted coefficients are used to meld DATA (SST from HyCOM) and ROMS components.
- Added new item (debug_write) to coupling metadata file coupling_esmf.dat to specify which excanged field(s) are written into NetCDF files during debugging (DebugLevel > 2) to avoid generating lot and lots of files:
'SST' 'sea_surface_temperature' ! standard name 'sea surface temperature' 't(:,:,N,itemp)', 'ROMS' ! source variable, ROMS 'C' ! source units 'Center' ! source grid-cell 'tsea', 'COAMPS' ! destination variable, COAMPS 'K' ! destination units 'Center' ! destination grid-cell 'SST' ! DATA Model file variable 'bilinear' ! regridding method 'none' ! unmapped extrapolation method .TRUE. ! connected to coupler .FALSE. ! debug write into a NetCDF file 273.15d0 ! importing add offset 1.0d0 ! importing scale
