Cloud detection by inversion of MAX-DOAS measurements
, 2015 Multi-Axis Differential Optical Absorption Spectroscopy (MAXDOAS)is a widely used technique for the detection of atmospheric trace gases, e.g. NO2, SO2, but also for the oxygen collision complex O4, whose atmospheric distribution is well known. By comparing measured O4 differential slant column densities (dSCDs) with modelled ones, information on ...
