relative and specific humidity missing #20

Include both relative and specific humidity in vocabulary.

In vocabulary for 'atmospheric state' https://vocabulary.actris.nilu.no/skosmos/actris_vocab/en/page/airhumidity -> specific humidity. For instruments (new matrix) -> relative humidity

Needs to be discussed at ET level.

We have both specific and relative humidity in Cloudnet products. These are well-defined quantities also found in CF conventions as specific_humidity and relative_humidity.

As a related issue, we also need definition for absolute humidity. This seems to be mass_concentration_of_water_vapor_in_air in CF conventions. What do you think?

I would prefer specific, relative and absolute humidity as these have well defined meanings. Humidity alone is open to interpretation

markusfiebig commented 7 months ago

draft: water vapour mass concentration, alt label : absolute humidity water vapour mass fraction, alt label: specific humidity water vapour liquid water saturation fraction, alt label: relative humidity with respect to water water vapour ice water saturation fraction, alt label: relative humidity with respect to ice

to be reconfirmed by @swr99ejo and @markusfiebig

Has been reconfirmed!

Has been implemented in dev, rolled out in next version.
