### Description

Calculates of scattering coefficient matrix for air.
This function calculates the scattering coefficient for air using a
fitted version from Stamnes et al., 2017 of the numerical results of
Bates, 1984. Internally it calculates the spectrum of scattering
coefficient matrices from the spectrum of scattering cross section matrices,
atmospheric pressure, temperature for one point in the atmosphere. The
function multiplies the cross sections with the number density of gas
molecules under the assumption of an ideal gas to get the coefficients.
The result is returned in gas_scattering_coef. The atmospheric pressure and
temperature state has to be specified by rtp_pressure,
rtp_temperature. The formula is accurate to 0.3 percent for wavelengths
between 0.205 and 1.05 micrometer.
