The result is the saturation vapour pressure in Pa units. On error nil is returned. The computations are based on a mixed-phase Tetens formula used by IFS for diagnostic purposes (see . See here on p116 for details from the latest model cycle (CY45R1, ) at the time of the writing of this documentation).
