English abstract:
A new methodology to derive the spatial distribution of clay pans from satellite
microwave data is presented. Soil moisture has a different temporal signature in clay
pans compared with other soils, which is directly reflected in the satellite-observed
brightness temperatures. Three years of Advanced Microwave Scanning Radiometer
Earth Observing System (AMSR-E) 6.9 GHz microwave observations were compiled
and analysed over continental Australia to identify clay pans. This led to the development
of a brightness temperature variance index (BTVI), which shows a strong
spatial correspondence to an existing soil texture map and the ability to map clay
pans for semi-arid regions. This simple method emphasizes the potential use of passive
microwave remote sensing for soil type mapping.
