Specifies a geographical area over which to carry out the interpolation, the default being for the whole globe. Enter coordinates (lat/lon) of an area separated by a "/" (North/West/South/East), or in Macro or Python provide a list, e.g. [north, west, south, east]; alternatively, use the assist button to define the area graphically.
Rotation
Rotation is specified by selecting a new coordinate for the South pole. In Python or Macro, enter [lat, lon]; in the GUI, enter lat/lon or use the coordinate assist button to graphically select the point.

Frame
Specifies the width of a frame within a given sub-area. The width of the frame is specified as an integer number of grid points inwards from a given area. See also frame - keyword in MARS/Dissemination request.
Wind Processing
Activates processing that is particular to wind fields. Possible options are:
- UV To UV: assumes that the input files come in pairs of U/V. The resulting values will be scaled by the cosine of their latitudes.
- VOD To UV: assumes that the input files come in pairs of vorticity and divergence. The resulting values will be scaled by the cosine of their latitudes.
Nabla
Activates a nabla (differential) operator processing on the fields. Possible functions are:
- Scalar Gradient: QQQ
- Scalar Laplacian: QQQ
- UV Divergence: QQQ
- UV Gradient: QQQ
- UV Vorticity: QQQ
- Off: do not perform any nabla operation
Nabla Poles Missing Values
QQQ. Possible values are On and Off.
Interpolation methods and parameters
...
Interpolation
Specifies the type of interpolation to be used on the fields. The default is Automatic, which selects either Linear or Nearest Neighbour based on an internal table of known parameters. If the parameter is unknown, the default will be Linear. The possible interpolation methods are:
- Linear: QQQ
- Bilinear: QQQ
- Conservative Finite Element: QQQ
- Grid Box Average: QQQ
- Grid Box Maximum: QQQ
- K Nearest Neighbours: QQQ
- Nearest LSM: QQQ
- Nearest Neighbour: QQQ
- Structured Bicubic: QQQ
- Structured Bilinear: QQQ
- Structured Biquasicubic: QQQ
- Automatic: see description above.
