二坝水库红外温度和水面温度观测系统架设目的在于为航空TASI、WiDAS和L波段飞行提供水体表面温度的数据。\n
\n观测地点：选择张掖城东14km,甘州区碱滩镇二坝村旁的二坝水库作为观测点。该观测点坐标：38°54'57.14\"N，100°36'57.39\"。\n
\n测量仪器：观测内容包括一个垂直对水面的SI-111红外温度探头，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，其出厂时默认设置的地表发射率为1，试验期间未进行黑体定标）。2个漂浮在水面以下0cm109SS-L温度传感器，数采为Campell CR-1000，自动采集，GPRS无线传输至综汇系统。探头架高3米，离岸距离3.4m。\n
\n测量时间：仪器从2012年5月27日起开始正常观测，至9月27日进行不间断地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：垂直水体表面温度（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的校正），水面0cm直接测量温度（WaterT_1，WaterT_2）。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。

\nMeasuring instrument: the observation contents include a si-111 infrared temperature probe perpendicular to the water surface and a si-111 infrared temperature probe observing the sky at a zenith angle of 35 degrees due south (the instrument was newly purchased in 2012, the default surface emissivity was 1 when it was delivered from the factory, and blackbody calibration was not carried out during the test). Two 0cm109ss-l temperature sensors floating below the water surface, data acquisition is Campell cr-1000, automatic acquisition, GPRS wireless transmission to the comprehensive collection system. The probe frame is 3M high and the offshore distance is 3.4m.\n
\nMeasurement time: the instrument starts normal observation from May 27, 2012 to September 27, 2012, continuously observes for 24 hours, records data once in 5 seconds, and outputs two groups of values in 5 seconds and 1 minute.\n
