The accumulated spaceborne observations at low microwave frequencies enable soil moisture retrieval with reasonable spatial resolution since 2002. This results in a timescale which is applicable for resolving climate change impact on soil moisture. In order to investigate these changes at the appropriate timescales the observations of multiple spaceborne microwave radiometers need to be combined and soil moisture retrieval algorithms developed accounting for the differences in these instruments. The analysis of the resulting global decadal soil moisture data record will require development of techniques to both enable agile handling of the large volume of the data set, and to identify soil moisture patterns and trends in a quantified way. The validation of the observed changes in the soil moisture distribution and water cycle will also require new approaches to quantifiably connect long term soil moisture record with energy cycle, plant activity and extreme weather events.

This research offers an opportunity to participate in the development of this data set and analysis of the climate change impacts using the data. The study utilizes microwave radiometer data from NASA SMAP, ESA SMOS, and JAXA AMSR-E and AMSR2 instruments. Candidates should have PhD in Hydrology, Geosciences, Environmental Sciences, or a related field. Previous experience in processing and analyzing spaceborne microwave radiometer data is expected. The work will be carried out as a member of a team but ability to work independently is essential and strong motivation for publishing is required.
