Calculates relative humidity with respect to ice, given temperature, mixing ratio, and pressure.

“Improved Magnus’ Form Approx. of Saturation Vapor pressure” Oleg A. Alduchov and Robert E. Eskridge https://journals.ametsoc.org/view/journals/apme/35/4/1520-0450_1996_035_0601_imfaos_2_0_co_2.xml

Parameters:

• t (xarray.DataArray) – Temperature in Kelvin

• w (xarray.DataArray) – Mixing ratio in kg/kg. Must have the same dimensions as temperature

• p (xarray.DataArray) – Pressure in Pa. Must have the same dimensions as temperature

Returns:

rh (xarray.DataArray) – Relative humidity. Will have the same dimensions as temperature
