Equipment

several Multi Axis DOAS (MAX-DOAS) instruments (Determination of trace gas profiles)

Imaging DOAS instrument (Determination of 2 D distributions of trace gases)

Optical Insitu-Monitors for SO₂ and CO₂

SO₂ Camera (two dimensional SO₂ distribution)

Raschig-Rohr (alkaline trap)

White cell (laboratory instrument, determination of mean trace gas concentration over a certain lightpath)

Method

Differential optical absorption spectroscopy (DOAS), passive and active, for the investigation of trace gas distributions, in particular free radicals (e.g. BrO, SO₂, CIO, OClO, OBrO, IO) in volcanic plumes as well as determination of SO₂ emission fluxes and total emission of acidic compounds.
