It includes X-band ground-based microwave radiometer observation (October 20-25, 2007), S-band ground-based microwave radiometer observation (October 20-25, 2007), K-band ground-based microwave radiometer observation (October 19-24, 2007) and Ka band ground-based microwave radiometer observation (October 20-24, 2007). The main observation target is the impact of ground freezing and thawing state on microwave brightness temperature. This data can provide basic data for the development and verification of Microwave Radiative transfer forward model and parameter inversion algorithm of frozen / thawed soil. The continuous observation of ground-based microwave radiometer is carried out in ARJO quadrat 1, and the surface type is dry natural grassland. The ground observation data includes two parts: self recording observation and manual observation
\n1) Self recording observation: the soil temperature data of 0cm, 5cm, 10cm, 15cm and 20cm obtained by the temperature probe, and the observation period is October 21-25, 2007; The shallow (0-5cm), 5cm, 10cm, 15cm and 20cm soil moisture obtained by TDR probe is observed from October 19 to 21, 2007, and the observation time steps of both are 5 minutes
\n2) Manual observation: including surface radiation temperature measured by hand-held red thermometer; 0cm, 5cm, 10cm, 15cm and 20cm soil temperatures measured by glass tube thermometer; The average soil temperature of 0-5cm measured by needle thermometer, the measurement time step is 30 minutes, and the observation period is October 19-21, 2007.
