Radiative Transfer Modeling (RTM)

The initial product of solar stray light measurements is Slant Column Density (SCD) which is the integrated concentration of trace gases along all light paths. This quantity can be inverted in order to quantify aerosol properties (optical and microphysical) and trace gas vertical information.
