Remote Sensing

The working groups in the remote sensing section are doing atmospheric science using microwave sensors from the ground and from science aircrafts. Other groups of this section are using satellite data to do special cartography of surface properties such as sea ice maps. The structure of the remote sensing section can be seen from the following diagram: [4.122 KB]

  • ASUR: Airborne Remote Sensing of the Stratosphere
  • Research in stratospheric ozone chemistry and in particular anthropogenic ozone destruction is one of the major research areas of the ASUR Group. Activities span the range from developing novel airborne sensors, conducting campaigns, retrieving of geophysical parameters and physical/chemical interpretation of results. The technique developed so far is unique in the sense that it allows to obtain vertically resolved profiles with excellent horizontal resolution of many species of importance in ozone chemistry.

  • RAM: Groundbased Remote Sensing of the Atmosphere
  • Ground based measurements of several atmospheric constituents and the physical interpretation of the data are the main research areas of the RAM group. We operate microwave radiometers for the measurement of ozone, water vapour and chlorine monoxide in the Arctic (Spitsbergen) and in Bremen. Measurement sites in Merida (Venezuela) and Greenland are under construction. One of the focal points of research is the chemical destruction of ozone in the Arctic.

  • Remote Sensing of Polar Regions
  • Sea ice is a sensitive climate change indicator as it is reflected in the drastic reduction of the Arctic sea ice cover during recent decades. To observe the remote and vast sea ice areas in the Arctic and Antarctic satellite remote sensing is the method of choice.
  • On this website you find sea ice datasets from satellite remote sensing observations produced at the University of Bremen. All datasets are research products provided without liability.

  • 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.

  • Trace gases and aerosol observations by the FTIR-spectrometry
  • Our work can be divided in field measurements and laboratory studies. The field observations are performed in close cooperation with the Alfred-Wegener-Institute for Polar and Marine Research, Bremerhaven/Potsdam. These observations include continues observations in the high Arctic at Spitsbergen (79°N, 12°E). Furthermore, the latitudinal variations of trace gases and aerosols are studied during ship cruises onboard the german research vessel Polarstern between 80°N and 70°S. The work programme can be divided into the following 4 subjects, which are partly discussed in the web page.

  • SuriMerc - Mercury Pollution in Suriname
  • SuriMerc is funded by the United Nations Environment Programme (UNEP) within the framework of “Supporting country efforts to take action on mercury pollution” and is related to the Global Mercury Project. The objective of SURIMERC is to build the necessary capacity in Suriname to assess the magnitude of the mercury contamination and to reduce mercury pollution by training miners in alternative extraction methods.
