摘要：

Particle size of soils plays a significant role in erosion potential and other mechanical properties. Most soils are dominated by the residual mineral quartz, which displays prominent reststrahlen bands in the 8-14 mum atmospheric window. The Earth Observing System (EOS) will likely provide world-wide multispectral imagery in the 8-14 mum region via the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument. The ratio of ASTER bands 10/14 can be used to estimate particle size in soils, if other ASTER bands are used to minimize the confusion factors provided by soil moisture, vegetation cover, soil organic content, and the presence of abundant minerals other than quartz, Use of band ratios minimizes the effects of poor surface temperature estimates, but maximizes the need for high signal-to-noise data.
