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. |
