In principle, the derivation functions will work regardless of the input units, as all units are internally
converted as necessary according to the specific formulae definitions.
However, the units string (see getGridUnits
) must be parseable. In the same vein,
the input units need to be convertible to the required ones. Unit consistency is internally achieved
by the function udConvertGrid
.
The formula is a valid aproximation for moist air (RH>50%), but can yield very inaccurate results otherwise, so use it with caution.

The adjustment formulae of pressure values to other levels are those routinely used by the WMO. These are described in the following technical report: https://www.wmo.int/pages/prog/www/IMOP/meetings/SI/ET-Stand-1/Doc-10_Pressure-red.pdf
