Paper Abstract

A field experiment was performed in winter wheat farmland at Baoding (Hebei province, China) from 13 Feb. 2009 to 19 Feb. 2009. In the experiment, brightness temperature of 8 channels (6.925GHz, 10.65GHz, 18.7GHz and 36.5GHz, horizontal and vertical polarization of each frequency), soil moisture, land surface temperature, snow character, and sublayer temperature are measured. The original purpose of the experiment is to character the drought monitoring ability of the microwave radiometer's channels. But during the experiment, there is a small snowfall process. So we got the radiometry characteristic corresponding with 4 statement of soil: wet soil, dry soil, frozen soil and snow covered soil (dry snow cover and wet snow cover). We do the analysis of all of the former cases. We also do the comparison of satelliteborne radiometer (AMSR-E) and the ground-based radiometer that we got using the 7days-measurement.The trend of the 2 measurement fit well.
