sasktran2.GroundViewingSolar

class sasktran2.GroundViewingSolar(cos_sza: float, relative_azimuth: float, cos_viewing_zenith: float, observer_altitude_m: float)

Bases: object

Defines a viewing ray that is looking at the ground from angles defined at the ground location. Note that

all of these parameters assumes straight line paths (i.e. no atmospheric refraction)

Parameters:

• cos_sza (float) – Cosine of solar zenith angle at the ground point [unitless]

• relative_azimuth (float) – Relative azimuth angle to the sun [rad] at the ground point. An angle of 0 degrees corresponds to the forward scattering plane.

• observer_altitude_m (float) – Observer altitude relative to the earth [m]

• cos_viewing_zenith (float) – Cosine of the viewing zenith angle at the ground point [unitless]
