Case E1: Rayleigh scattering, US standard atmosphere
In this case we include the US standard atmosphere, the corresponding Rayleigh scattering optical thickness profile is provided for 450nm.
Setup:
model atmosphere US-standard, scattering optical thickness provided in file tau_rayleigh_450nm_usstd.dat. The file includes 2 columns where the first is the altitude of the layer boundaries in km, and the second is the layer optical thickness (e.g. the value for 0 km corresponds to the optical thickness for the layer from 0 to 1 km).
wavelength: 450 nm
no molecular absorption
Rayleigh depolarization factor: 0.03
surface albedo: 0
Earth radius: 6371 km
Height of atmosphere: 120 km
E1_1: Polarized zenith radiance as a function of sun position
solar zenith angle: sza: 80°-100° (90° corresponds to horizontal direction)
solar azimuth angle: saa: 65°
viewing zenith angle: 5°
viewing azimuth angle: 0°
D1_2: Limb radiance at top of atmosphere for tangent heights between 0 and 90 km
viewing zenith angle at TOA: vza: corresponding to tangent heights 0-90km, 2km increment
