机场荒漠红外温度系统架设目的在于为航空TASI、WiDAS和L波段飞行提供地面定标观测数据。\n
\n观测地点：选择张掖机场旁的大面积、均质和平坦的荒漠作为观测点，植被为稀疏低矮的灌丛。该观测点坐标：38°46'41.30\"N，100°41'48.10\"E。\n
\n测量仪器：观测探头为一个垂直对地的S1-111红外温度探头和一个正南天顶角35度对天观测的SI-111红外温度探头（2012年新购置仪器，其出厂时默认的地表发射率为1，试验期间未进行黑体定标），Campell CR1000数采自动记录，探头架高4米，仪器朝向正南。\n
\n测量时间：仪器从2012年6月10日起开始正常观测，至今进行不间断地24小时观测，5秒钟记录一次数据，输出5秒钟和1分钟2组值。\n
\n数据内容：地表温度（TarT_Sur，未进行地表比辐射率、背景温度的校正）,对天空温度(TarT_Atm,未进行天空背景比辐射率校正)。数据最终被存储为1天1个独立文本文件，数据命名方式：数据格式+观测点名称+数据采样时间+日期+时间.dat。详细的数据表头信息见数据内的数据表头说明。

Campell CR1000 data is automatically recorded, the probe frame is 4m high, and the instrument faces due south.\n
\nMeasurement time: the instrument has been observing normally since June 10, 2012. Up to now, it has been observing continuously for 24 hours, recording data once in 5 seconds, and outputting two groups of values in 5 seconds and 1 minute.\n
\nData content: surface temperature (tart)_ Sur, without correction of surface specific emissivity and background temperature), sky temperature (tart)_ ATM, without sky background specific emissivity correction). The data is finally stored as an independent text file for one day. The data naming method is: data format + observation point name + data sampling time + date + time. Dat.
