Comment:
During the cruise MSM58/2, a MAX-DOAS instrument was installed on Maria S. Merian. The instrument's measurements were used to retrieve the atmospheric abundance (in the form of slant column densities) of different trace gases. This dataset contains daily averaged slant column densities of glyoxal (CHOCHO), measured at different elevation angles, as well as a vertical column density (derived from the 30 degree measurement).
