Dynamic Land Surface Classification in Microwave Frequencies Yudong Tian, Hasan Jackson, Christa D. Peters-Lidard, and Kenneth W. Harrison

2 1.Motivation: S1 uses TELSEM-based static surface classes. They will miss dynamic changes: snow, freeze/thaw, flooding, etc. 2.Method: some Tb indices can tell surface characteristics in real-time. 3.Data: AMSR-E Tb

3 Two Tb indices can jointly differentiate different surface types SSI=Tb18V-Tb36V

4 Partition of MPDI-SSI space into 9 classes

5

Summary: 1. Proposed and tested a new classification scheme 2. Can be used in real-time with Tb data only. 3. Can capture day-to-day class variations.
