If the input source is mars the input GRIB data is retrieved from the MARS archive. When Prepare mode is forecast the input source can also be set to file. In this case the GRIB file specified in Input file will be used as input data.
...
Specifies the full path to the file containing the input GRIB data. Available when Prepare mode is forecast and Input source is file. The input file must contain the following fields:
| Filed type | Parameters | Steps |
|---|---|---|
| surface fields | ["sd","msl","tcc","10u","10v","2t","2d","sp", "z","lsm","lcc","mcc","hcc","skt", "stl1","swvl1"] | all |
| surface fluxes | ["lsp","cp","sshf","ewss","nsss","ssr"] | all + |
| model level fields | ["u","v","t","q","etadot"] | all |
| surface analysis | ["sdor","cvl","cvh","sr"] | valid for step 0 |
surfFluxParams require additional fields for step=0. The fluxes for this step are computed from the previous forecast.
E.g. for the 0 UTC run the flux for step 0 is computed from step=6 and step=3 of the 18 UTC run
on the previous day (when we have 3 hourly steps). So in this case step=3 and 6 are needed
for surfFluxParams from the 18 UTC run.
Date
Specifies the run date of the forecast. Available when Prepare Mode is forecast.
...
Specifies if the input GRIB fields are needed need to be interpolated onto a target grid specified by Area and Grid. The possible values are on/off. Available when Input source is file. The default value is: on.
