Workspace Method vmr_fieldSetRh
Description
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.
