Description

The variable ANGLE defines the Visual Zenith Angle (in [deg]), which varies between 0 deg (for nadir-looking instruments, default value) to 90 deg (for limb-pointing instruments).

This variable defines the length and geometry of the target-sensor optical path, which increases/decreases the effects of absorption and scattering caused by gasses and aerosols.
