%X During April 5-8, 2008, the bare soil (N38 º 03.639 ') was leveled in the Aru intensive observation area; E100º26.793'； 2998m) carried out continuous observation with multi frequency, multi polarization and multi angle ground-based microwave radiometer, including S-band ground-based microwave radiometer observation (April 6-8), C-band ground-based microwave radiometer observation (April 7-8, 2008), K-band ground-based microwave radiometer observation (April 5-8) and Ka band ground-based microwave radiometer observation (April 5). The main observation target is the influence of surface freezing and thawing state on microwave brightness temperature. The site is flat bare soil, with an initial dry water content of about 14%, and then watered evenly manually, with a water content of about 30%. The Soil Hydrothermal observation field is arranged in the east of the microwave radiometer observation field, including 5cm automatic soil temperature observation (10 minute observation step); Manual observation of 5cm, 10cm, 20cm and 30cm soil temperature (needle thermometer with 1-hour observation step); Automatic observation of 5cm, 10cm, 20cm and 30cm soil moisture (10 minute observation step). This data can provide basic data for the development of Microwave Radiative transfer forward model and microwave remote sensing inversion model of frozen / thawed soil. This data set includes 7 files, namely: S-band ground-based microwave radiometer observation data, C-band ground-based microwave radiometer observation data, K-band ground-based microwave radiometer observation data, Ka band ground-based microwave radiometer observation data, automatic soil temperature observation data, manual temperature observation data and automatic soil moisture observation data. Moisture data and temperature data are stored in Excel.
