Satellite remote sensing of Arctic surfaces
Lead: Angelika Humbert, AWI


The objectives of this WP are:

  • to streamline satellite remote sensing data flows, incl. cal/val and develop novel products
  • to develop analysis methods for snow surfaces, biomass and extraction of natural resources
  • to characterize glacier tomography with synergistic operation of satellites and aircraft remote sensin
  • to contribute to strategic development of comprehensive EO needs and opportunities in the polar areas

The current and upcoming satellite missions will greatly enhance our capability of Earth observation, which in polar areas with a very sparse in-situ station network will give us spatial coverage to monitor the large area.
