Workspace Method vmr_fieldSetRh


Sets the first H2O species to have a constant relative humidity (RH).

The water vapour saturation pressure is obtained by water_p_eq_agenda
and the setytings in this agenda determines if the RH is e.g. defined
with respect to liquid, or a combination of liquid and ice.

Only the first H2O species is modified.

The default value of *vmr_threshold* aims at avoiding changing VMRs
above the tropopause.
