Data input parameters
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.
Source
Specifies the GRIB file path.
Data
Drop a MARS Retrieval or a GRIB file icon inside this icon field. Note that you should specify either Source or Data, not both. In Python or Macro, supply a Fieldset object.
Output Grid definition parameters
Grid Definition Mode
Select a method for specifying the output grid.
- Grid: supply a valid string or list of numbers in the Grid parameter
- Template: supply a template GRIB file, whose grid structure will be used to generate the output GRIB; use either Template Source or Template Data to specify the template
- Lambert Conformal: supply details of the output grid in the set of Lambert grid definition parameters
- Lambert Azimuthal Equal Area: supply details of the output grid in the set of Lambert grid definition parameters
Template Source
If Grid Definition Mode is set to Template, supply the path to a template GRIB file; the output GRIB will use the same grid as the template.
Template Data
If Grid Definition Mode is set to Template, supply a GRIB-based data object in the Data parameter; the output GRIB will use the same grid as the template.
Grid
Supply a grid definition as described here: grid - keyword in MARS/Dissemination request.
Examples of valid grid definitions:
| GUI | Python / Macro | Result |
|---|
| 1/1 | [1, 1] | A regular lat/lon grid with 1x1 degree point spacing |
| 0.25/0.25 | [0.25, 0.25] | A regular lat/lon grid with 0.25x0.25 degree point spacing |
| O1280 | "O1280" | A reduced Gaussian grid, octahedral with 1280 latitude lines between the pole and equator |
| N640 | "N640" | An 'original' reduced Gaussian grid, with 640 latitude lines between the pole and equator |
| F400 | "F400" | A regular Gaussian grid, with 400 latitude lines between the pole and equator |
