[joergklausen]

The proposed variable is indeed synonymous to the existing variable (210). The following description is proposed:

"The amount, usually expressed in millimeters or inches of liquid water depth, of the water substance that has fallen at a given point over a specified period of time. (source: AMS Glossary, https://glossary.ametsoc.org/wiki/Precipitation)

It is suggested for the OSCAR/Space platform to adopt the name 'Amount of precipitation'.

See https://hydro.geodab.eu/hydro-ontology/concept/65 for the equivalent in the WHOS ontology.

We also have the CF convention definition, see https://vocab.nerc.ac.uk/standard_name/precipitation_amount/
