sasktran2.SolarAnglesObserverLocation

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

Bases: object

Defines a viewing ray that is defined at a location defined from the solar angles. Note that all of these parameters assumes straight line paths (i.e. no atmospheric refraction). This differs from sk.GroundViewingSolar in that the angles are defined at the observer location, not the ground location.

Parameters:

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

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

• cos_viewing_zenith (float) – Cosine of the viewing zenith angle at the observer point. Positive angles are viewing up, negative angles are viewing down. [unitless]

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