该数据集包含2014年07月22日至2016年07月19日在黑河下游混合林站和超级站观测的组分温度数据。测量地点坐标分别为101.1335E、41.9903N和101.1374E、42.0012N，海拔约874m。所使用的红外辐射计型号为SI-111，数采为CR800。\n
\n混合林站使用两支传感器分别观测光照胡杨（南侧）和阴影胡杨（北侧）的组分温度。两支传感器架设高约5m，距目标约1m，水平观测。超级站使用两支传感器分别观测裸土和柽柳的组分温度。观测裸土的传感器架设高度约2m，观测天顶角约45°；观测柽柳的传感器架设高度约1m，距被测目标约0.5m，水平观测。

\nThe mixed forest station uses two sensors to observe the component temperatures of illumination Populus euphratica (south side) and shadow Populus euphratica (north side) respectively. The two sensors are about 5m high and 1m away from the target for horizontal observation. The super station uses two sensors to observe the component temperatures of bare soil and Tamarix respectively. The erection height of the sensor for observing bare soil is about 2m, and the observation zenith angle is about 45 °; The sensor for observing Tamarix is about 1m high and about 0.5m away from the measured target
