The DOAS-group at the Institute of Environmental Physics (IUP), University of Bremen is working on applications of the Differential Optical Absorption Spectroscopy (DOAS) method to measurements of atmospheric constituents from different platforms:
|
|
|
Ground-based measurements from the BREDOM network, a system of UV/visible spectrometers observing scattered sunlight at 5 stations from low to high latitudes in the Northern hemisphere. The measurements are directed towards both stratospheric and tropospheric species and are closely associated to the NDSC network.
|
|
|
Satellite borne measurements from GOME and SCIAMACHY. Using the DOAS method, atmospheric columns of a number of species can be retrieved, such as O3, NO2, BrO, and OClO in the stratosphere and NO2, SO2, BrO, and HCHO in the troposphere. Our activities enclose data retrieval, validation, and interpretation of the measurements.
|
|
|
Air-borne DOAS measurements. Airborne multi-axis (AMAXDOAS) measurements can be used to study stratospheric chemistry, tropospheric pollution and even local emissions such as from power plants. The data are also used for the validation of satellite measurements.
