CO2

CO2 mixing ratio

Attributes

float | continuous | dynamic | ppmv | medium

Description

The variable CO2 overwrites the predefined CO2 total mixing ratio from the selected atmospheric model in MODEL by the user input CO2 value in [ppmv]. Typical worldwide and annual CO2 mixing ratios range from 350 ppmv to 420 ppmv, with typical mean values around 395 ppmv. Setting the value to -1 (default value) will use the preset CO2 concentration from the selected atmospheric model profile. Note that libRadtran requires units of molecules per cm2. ALG does this unit conversion automatically.
