AB  - A set of surface temperature and uplink / downlink short wave observation system is set up on the roof next to the village point of EC matrix 4 to provide ground calibration observation data for aviation TASI, widas and L-band flights. Observation site: a large area and homogeneous earth house roof of Shiqiao village, Xiaoman Town, Ganzhou District, Zhangye City, Gansu Province was selected as the observation point. The observation point is located on the roof. It is relatively flat and uniform. There is no shelter from tall trees around it. It is about 20m away from the southwest of point EC4. The coordinates of the observation point are 38 ° 52 ′ 38.50 ″ N and 100 ° 21 ′ 27.00 ″ E. Measuring instrument: the observation probe is a vertical s1-111 infrared temperature probe (newly purchased in 2012, the default surface emissivity is 1 when it leaves the factory, and blackbody calibration is not carried out during the test). It is composed of two Cmp3 albedo meters (one upward and one downward), the probe frame is 1.0m high, and Campell cr850 data acquisition and automatic recording. Probe orientation: the instrument arm is 3M long and parallel to the edge of the house, with an azimuth of 156 ° and 66 ° East by south Measurement time: the instrument began normal observation on June 23, 2012 and was removed on September 20, 2012. During this period, it was observed continuously for 24 hours, recorded once in 5 seconds, and output two groups of values in 5 seconds and 1 minute. Data content: surface temperature observation data, uplink / downlink shortwave radiation data, and the final albedo can be calculated. The temperature observation data mainly includes the body temperature (SBT) of the sensor of si-111 infrared temperature probe_ C) . surface temperature observed by sensor (target)_ C. No correction of surface emissivity and background temperature). The data is finally stored as an independent text file for one day. The data naming method is: data format + obser
