"Remote sensing for monitoring of land surface hydrology at high latitudes within the framework of the ESA DUE Permafrost and STSE ALANIS-Methane projects";
Time series of a wide range of biogeophysical parameters from
satellite data are available to date on a global scale. A few initiatives focus on their
improvement and validation in high latitudes. For example the DUE Permafrost and STSE
ALANIS-Methane, which are activities funded by the European Space Agency, focus on this
ALANIS Methane is a research project to produce and use a suite of relevant earth
observation (EO) derived information to validate and improve one of the next generation
land-surface models and thus reduce current uncertainties in wetland-related CH4 emissions.
The task of the ESA DUE Permafrost project is to build up an Earth observation service for
high-latitudinal permafrost applications.
Results which are shown in this paper contribute to both.
Microwave sensors are of special interest in this context due to their independence on cloud
conditions and illumination of the Earth Surface. They can be used for derivation of land
surface temperature, snow properties and land surface hydrology. The latter includes near
surface soil moisture and inundation. Such parameters are of importance for studies on e.g.
permafrost and land-atmosphere exchange.
Datasets derived from active microwave instruments operating in C-band have been analysed
with respect to their usability at high latitudes. Several examples from western Siberia are
