2012 Annual Report
1) Phase 1: Apply quality control to existing satellite-based surface soil moisture products. 2) Phase 2: Examine the cross-calibration between existing satellite-based surface soil moisture products. 3) Phase 3: Adapt an Ensemble Kalman filter to integrate the (quality controlled and cross-calibrated) remote sensing products with surface temperature predictions from land surface model. 4) Phase 4: Evaluate the resulting surface temperature product and surface soil moisture retrievals obtained using the surface temperature product.
Objective #1. Develop a method to fuse temperature observations from multiple satellite thermal and microwave satellite sensors to create a multi-year climatology of diurnal land surface temperature.
Objective #2. Produce a validated, continuous temperature data set that spans the decade of 2003-2013, with a 0.25 degree spatial and 3 hourly temporal resolution.
Objective #3. Evaluate near-real-time capability for use in operational satellite retrieval methods that utilize temperature estimates at the exact overpass time of that satellite, as demonstrated within Advanced Microwave Scanning Radiometer for Earth Observing System (AMSR-E) and Aquarius soil moisture retrievals.
The project is on schedule with regards to the completion of these tasks. Objective #1 has been completed and documented in a peer-reviewed manuscript. Work is ongoing for Objective #2 (preliminary global products have been generated, but evaluation of these products is still on-going) and is expected to be completed by fall 2013. Preliminary work on Objective #3 has started.
