Geopoints

The geopoints command generates output compatible with Metview. The user supplies a single column (e.g. obsvalue@body) and varno (name or code). Currently the level is set to zero regardless of the contents of the odb file. This command is experimental and not guaranteed to work.

Usage

usage: py3odb geopoints [-h] -c COLUMN -v VARNO [-w WHERE] filename

Generate a standard 6-column geopoints file for Metview.
You must supply the filename, column, and varno.  You may use the
varno name or code.

Examples:
    $ py3odb geopoints sample.odb -c obsvalue@body -v 39
    $ py3odb geopoints sample.odb -c bgvalue -v t2m

See https://apps.ecmwf.int/odbgov/varno/

positional arguments:
  filename              The ODB2 filename.

optional arguments:
  -h, --help            show this help message and exit
  -c COLUMN, --column COLUMN
                        The column to include (e.g. obsvalue@body).
  -v VARNO, --varno VARNO
                        The varno to include.  May be either name or code.
  -w WHERE, --where WHERE
                        Adds a conditional to the SQL query.
