黑河流域地表温度同步观测的目的在于获取WiDAS飞行期间不同位置不同下垫面的同步温度，用于支持航空飞行WiDAS资料反演地表温度的验证和尺度效应分析。\n
本次试验的观测时间为2012年8月1日，选取了黑河流域上游西支扎马什克流域的2个点和东支八宝河流域的4个点周围的不同下垫面温度进行了同步观测，利用两种仪器测量不同位置的地表辐射温度，包括固定自记点温计（北师大3#）和手持式红外温度计（寒旱所H1#、H3#、H4#，北师大B1#、B2#），其中八宝河流域中的一个点使用的是固定自记点温计，自动每6秒记录一次温度，观测下垫面为天然草地。其它5个点的地表温度采用手持式红外温度计人工观测，在WiDAS进入观测点上空时进行观测。每个仪器在使用之后均进行了黑体标定。每一观测点选取周围较典型的下垫面进行观测，观测的下垫面主要有草地、河流水面、河滩、砾石等，其中部分下垫面配有相应的照片。\n

The purpose of synchronous observation of surface temperature in Heihe River Basin is to obtain the synchronous temperature of different underlying surfaces at different positions during widas flight, which is used to support the verification and scale effect analysis of inversion of surface temperature from airborne widas data.\n
The observation time of this test is August 1, 2012. Different underlying surface temperatures around two points in zamashk basin, the West Branch of the upper reaches of Heihe River Basin, and four points in Babao River Basin, the East Branch of Heihe River Basin are selected for synchronous observation. Two instruments are used to measure the surface radiation temperature at different locations, including fixed self recording point thermometer (Beijing Normal University 3#) and handheld infrared thermometer (cold and drought Institute h1#, h3# H4 #, Beijing Normal University B1 #, B2 #), in which a fixed self recording point thermometer is used at one point in Babao River Basin, which automatically records the temperature every 6 seconds, and the underlying surface is observed as natural grassland. The surface temperature of the other five points is manually observed by hand-held infrared thermometer when widas enters the sky above the observation point. Each instrument is calibrated in black after use. Typical underlying surfaces around each observation point are selected for observation. The observed underlying surfaces mainly include grassland, river surface, beach, gravel, etc., and some of the underlying surfaces are equipped with corresponding photos
