This MODULE contains two SUBROUTINEs that calculate the specific humidity at saturation as a function of air pressure and temperature.
The two SUBROUTINEs differ only in that qsatfjh operates on an array whereas qsatfjh2 operates on single element REALs.
Warning: qsatfjh2 is redundant and the code should be changed to only use qsatfjh.
This SUBROUTINE evaluates the specific humidity (water vapour mixing ratio) at saturation (in kgkg), at a given air temperature (in C) and air pressure (in hPa) for an array of size mp.
