Column

This icon converts GRIB data into a Geopoints file. This transformation has two effects: the result is in ASCII format, and is stored as a set of separate points rather than as a grid.  Note that this icon can only convert GRIB data which is in a supported gridded format - for example, data in spherical harmonics cannot be converted.

The macro language equivalent is grib_to_geo().

...

Specifies the data to be converted. Only the first field will be converted. Drop any icon containing or returning GRIB data. This may be, for example, a GRIB file, a MARS Retrieval (of observations) icon or a Macro which returns GRIB data.

Output

Specifies the output format you want. Specify one of the geopoints formats (Geographical Points, Geographical Polar Vectors or Geographical X Y Vectors).

Geopoints Format

 Specifies which of two Geopoints formats should be used for the output - either Traditional (6 columns including date, time and level) or XYV (just 3 columns - longitude, latitude and value). See Geopoints for details of these formats.
