This data set includes 7 files, which are: 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, soil temperature automatic observation data, temperature manual observation data, soil moisture automatic observation data. The moisture data and temperature data are stored in Excel.
During April 5-8, 2008, continuous observation with multi frequency, multi polarization and multi angle ground-based microwave radiometer was carried out in the leveling bare soil of aryo encryption observation area, 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
Good data quality
