Equipment

Differential Optical Absorption Spectroscopy (DOAS)

Multi-Axial DOAS (MAX-DOAS) (passive method for the determination of heigth profiles)

Long-Path DOAS (active method for long distances)

Cavity Enhanced DOAS (active insitu-measurement of air samples)

Imaging DOAS (for the determination of 2D-profiles)

Method

Research of the concentration of free radicals (e.g. O₃, SO₂, OH, HO₂, NO₂, NO₃, ClO, BrO, IO, OIO, organic peroxy radicals) and aerosols in the troposphere.
