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 | Forecast steps (defined in 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 + additional steps (see the comment below) |
| model level fields | ["u","v","t","q","etadot"] | all |
| surface analysis | ["sdor","cvl","cvh","sr"] | required for the valid |
| date of step 0 |
surfFluxParams require additional fields for step=0. The fluxes for this step are computed from the previous forecast.
EThe surface fluxes are accumulated fields and for the de-accumulation process they also require the step preceding the first step. We have a special case when the first step is 0 because in this case we need two additional steps but from the previous model run! E.g. for the a 0 UTC model run the flux for step 0 is computed when we use 3 hourly steps we need the fluxes from step=6 and step=3 of the 18 UTC run on 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.
