Input definition
...
Input data may be specified either by giving a path in the Source parameter or by giving a GRIB-based data object in the Data parameter. Note that you should specify either Source or Data, not both.
...
It is up to the user to specify if the input consists of wind fields. Set this appropriatelly in order to perform the correct processing.
Possible options are:
| Converts pairs of Cartesian components vector fields (spectral) U/V to (gridded) u/v. This option is required if regridding wind fields on/to a rotated grid. Note: assumes that the input come in pairs of alternating U/V. |
| Converts pairs of (spectral) vo/d fields into (spectral) U/V or (gridded) u/v. In case of gridded output, scaling by the cosine of their latitudes is applied (as above.) Note: assumes that the input come in pairs of alternating vo/d. |
| Each processed field is treated individually. |

Select one of the predefined names from the following:
| binary-based LSM sourced from MODIS Land Water Mask MOD44W (see reference) |
| binary-based LSM at high resolution (legacy, pre-climate files version 15) |
| GRIB-based IFS supporting climate files version 15, on this specific grid |
| (as above, for this grid) |
| (as above, for this grid) |
| (as above, for this grid) |
| (as above, for this grid) |
| (as above, for this grid) |
LSM File Input/Output
Provide the path to an input/output LSM GRIB file.

Activates a nabla (differential) operator processing on the fields. Possible options are:
| Scalar field gradient (∇) |
| Scalar field Laplacian (∇2) |
| Vector (u/v) field gradient (∇) |
| Vector (u/v) field divergence (∇⋅) |
| Vector (u/v) field vorticity or curl (∇×) |
| no differential processing |
