Perform a Gaussian process interpolation of atmospheric parameters. It relies on precalculated atmospheric coefficients at a subset of spatial locations stored in a file. The file has each coefficient defined for every radiance channel, appearing in the order: (1) atmospheric path reflectance; (2) spherical sky albedo; (3) total diffuse and direct transmittance of the two-part downwelling and upwelling path; (4) extraterrestrial solar irradiance; (5) cosine of solar zenith angle. :type reference_radiance_file:
