Tandem-L will deliver a unique global data set for numerous scientific applications in the fields of climate research, geodynamics, glaciology, oceanography and hydrology, as well as for communal and statutory duties. The science goals and requirements of the users from the different applications are articulated around one main topic: to achieve a better understanding of the dynamic processes of the Earth system. Thanks to the innovative imaging techniques of Tandem-L and the expertise gained through the HGF Alliance EDA, a quantum leap can be expected in the modelling and extraction of biophysical/geophysical parameters for following research areas.

Climate Research

  • Global determination of forest biomass and its temporal variation, in order to assess the status and quantify the proportion of biomass in the terrestrial system, and, hence, to obtain a complete picture of the carbon cycle (CO2 sinks and sources) for the first time.
  • Monitoring of melting processes in snow and ice regions.
  • Measurement of ocean currents.
  • Monitoring of the spread and seasonal change of wetlands.
  • Quantification of variations in near-surface soil moisture.

Biodiversity indicators:

  • Global monitoring of forest structure, such as forest height and vertical forest
    profile, and the global seasonal and yearly change.
  • Global monitoring of degradation and damage of forests.
  • Quantification of the biodiversity and its variation, determined indirectly from the
    forest structure and biomass distribution.

Earth dynamics indicators:

  • Observation of topographic variations with millimetre accuracy (e.g. earthquakes, volcanoes), in order to improve the understanding of possible events and contribute to prediction models.
  • Identification and provision of infrastructure information in disaster areas, in order to assist aid measures after catastrophes.
