Microwave refractive index due to gases in planetary atmospheres.

The refractivity of a specified gas mixture is calculated and added to refr_index_air. To obtain the complete value, refr_index_air should be set to 1 before calling this WSM. This applies also to refr_index_air_group.

The expression used is non-dispersive. Hence, refr_index_air and refr_index_air_group are identical.

Uses the methodology introduced by Newell&Baird (1965) for calculating refractivity of variable gas mixtures based on refractivity of the individual gases at reference conditions. Assuming ideal gas law for converting reference refractivity to actual pressure and temperature conditions. Reference refractivities are also taken from Newell&Baird (1965) and are vailable for N2, O2, CO2, H2, and He. Additionally, H2O reference refractivity has been derived from H2O contribution in Thayer (see refr_index_airMicrowavesEarth()) for T0=273.15K. Any mixture of these gases can be taken into account.
