Arbeitsgruppen: Physik und Chemie der Atmosphäre

Ozone over Europe: Go to the Archive Gesamtozongehalt in Dobsoneinheiten [DU] über dem europäischen Kontinent aus der GOME Level 2 Near-Realtime Auswertung.
SCIAMACHY (Scanning Imaging Absorption Spectrometer for Atmospheric CHartographY) is a spectrometer designed to measure sunlight, transmitted, reflected and scattered by the earth atmosphere or surface in the ultraviolet, visible and near infrared wavelength region (240 - 2380 nm) at moderate spectral resolution (0,2 - 1,5 nm).
GOME (Global Ozone Monitoring Experiment) is a nadir viewing UV/VIS spectrometer aboard the ERS-2 satellite. The scientific projects at IUP encompass: radiative transfer modelling, retrieval algorithm development, validation of GOME data products, and scientific case studies. The whole GOME data can now be found at one place.
The DOAS (Differential Optical Absorption Spectroscopy) group is using the DOAS method to retrieve atmospheric trace gas concentrations from UV/visible spectra of scattered sunlight. The method is applied to data from the GOME and SCIAMACHY satellite instruments, aircraft measurements and the data from the BREDOM network of ground-based UV/visible instruments.
Molecular Spectroscopy and Chemical Kinetics: Our work is to provide accurate reference data for atmospheric remote sensing, to study molecular physics and chemistry related to atmospheric problems, and to determine atmospheric concentrations by optical methods.
ELECTRONICS OPTICS & SENSORS GROUP: The main areas are electronics and optics specialties as well as design and test of airborne and balloonborne sensors and components.
TROLAS: The activities of the TROLAS group (Tropospheric in-situ observations and laboratory studies) of the Institute of Environmental Physics of the University of Bremen (IUP-UB) focus on the investigation of different aspects of the atmospheric chemistry which are closely related to the photochemistry and the mechanisms of free radical reactions involved in the formation and depletion of O3 in the troposphere.
Aerosol and cloud research: Main topic of this group is the investigation of global optical and microphysical parameters of clouds and aerosols from space.
OVOC: OVOC emissions: A new Emmy-Noether Research Group, funded by the DFG to characterize emissions of oxygenated volatile organic compounds from the biosphere, using micrometeorological techniques in conjunction with Chemical Ionization Mass Spectrometry.
Paleozon: Modelling possible impacts of large changes of geomagnetic intensity on the atmospheric composition using a 2 D version of the SLIMCAT model. Specifically, the impact of large solar proton events on the chemical composition and radiative balance of the atmosphere is investigated.
SCIAmetals: The project's objective is the monitoring of metal species in the atmosphere, in particular in the mesophere. Being excited mainly by sunlight metal atoms and ions (e.g. Fe, Mg, Na, Si, Cr) emit light at wavelengths in the UV/Vis. These emissions are retrieved from SCIAMACHY data and used to obtain global concentration profiles of metal species.
GeoTROPE (Geostationary Tropospheric Pollution Explorer): The scientific objective of the GeoTROPE mission is to investigate and assess the importance of anthropogenic activity and natural phenomena on the changing tropospheric composition, linking diurnal with seasonal to annual timescales, and regional with continental to global spatial scales.
SCIATRAN: The radiative transfer program has been designed to allow fast and accurate simulation of radiance spectra as measured or expected to be measured from space with the passive remote sensing UV-Vis-NIR spectrometers GOME.
BRAPHO (BRemens ATmosphärisches PHOtochemische Modell): Die Gruppe beschäftigt sich mit der Modellierung der Chemie und Physik der Atmosphäre. BRAPHO wurde entwickelt, um photochemische Prozesse in der Atmosphäre zu simulieren.
