Constants, Units, Spectra, Basic Gas Calculations This release marks the first usable version of PARMESAN. With PARMESAN you can now: - calculate (and plot) power spectra with several settings - convert between trace gas particle ratio and mass density - calculate temporal (e.g. diurnal) cycles - calculate potential temperature All physical functions accept pandas objects, normal numbers and also pint units. There is also an (optional) ”explicit unit mode” which makes sure a pint unit is always handed with each value.
