Description

The variable GNDALT defines the altitude (in [km]) of the ground target, which varies from 0 km (sea-level, default value) to 9 km.

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