UERRA details
| DefinitionThe | ratio of the partial pressure of water vapour to the equilibrium vapour pressure of water at the same temperature on a pressure levelRelative humidity is defined with respect to saturation of the mixed phase, i.e. with respect to saturation over ice below -23C and with respect to saturation over water above 0C. In the regime in between a quadratic interpolation is applied. |
