O3 column concentration

Description

The variable O3 overwrites the predefined O3 total column concentration from the selected atmospheric model in MODEL by the user input O3 value (in [atm-cm]). Typical worldwide and annual O3 concentrations range from 0.15 atm-cm (Ozone depletion at the south pole) to 0.45 atm-cm, with typical mean values around 0.315 atm-cm. Setting the value to -1 (default value) will use the preset O3 concentration from the selected atmospheric model profile. Note that libRadtran requires units of Dobson Unit (100 DU=0.1 atm-cm). ALG does this unit conversion automatically.
