International Workshop on

Terrestrial Water Cycle Observation and Modeling from Space: Innovation and Reliability of Data Products

Background

The last ten years of Earth Observation have witnessed two simultaneous major developments: an increasing diversity of primary measurements and a concerted effort of the Earth Observation community to develop and use higher level data products. This has been particularly true for observations to capture the complexity of the terrestrial water cycle. Two fundamentally different but complementary groups of state variables need to be captured: the amount of water in the Earth System and the response of the land surface to water availability.

The former can be observed globally using microwave radiometry at multiple frequencies, while the latter requires multispectral radiometry of reflected and emitted light. In both cases current data records extend to about 30 years, thus paving the way for analyses of climatological relevance.

The simultaneous development of computational technology has brought many new actors to the field of development and generation of higher level data and information products. While this has stimulated competition and innovation, the knowledge gap and the inherent uncertainty of primary measurements led to algorithms and data products which show evident disagreements.

Further progress requires the systematic and on-going evaluation of competing data and information products according to precise protocols to pin-point the precise causes of observed disagreements.

The Group on Earth Observations (GEO) is fostering international cooperation on earth observations with a number of societal benefit foci, including water resources. The Global Energy and Water Exchanges (GEWEX) Project of the World Climate Research program (WCRP) places a renewed emphasis on the exploitation of improved data sets of precipitation, soil moisture, evapotranspiration, and related variables.

The workshop aims at providing a state-of-the-art review of current satellite data products on the terrestrial water cycle generated using the primary measurements by satellite developers and operators of all Nations.

Emphasis will be on identifying current shortcomings and develop protocols for the comparative evaluation of higher level data products towards improved accuracy and reliability.
