HiWATER: Dataset of surface temperature and albedo on village roof in the middle reaches of the Heihe River Basin

A land surface temperature and upward/downward shortwave radiation observation system was set up on the roof, which locate on the edge of No.4 eddy covariance system (EC4) of the MUlti-Scale Observation EXperiment on Evapotranspiration over heterogeneous land surfaces 2012 (MUSOEXE-12). This observation site can offer in situ calibration data for TASI, WiDAS and L band sensor used in aerospace experiment.Observation Site:This point is located in a large and homogeneous adobe roof in Shiqiao Village, Xiaoman Town, Zhangye City. Land surface of observation site is relatively flat and uniform, and also not tall trees around. It’s about 20 meters away from southwest No.4 eddy covariance system (EC4) observation points. The coordinates of this site: 38°52′38.50″ N，100°21′27.00″ E。Observation Instrument:Observation system is composed of a SI-111 infrared radiometer (Campbell, USA) installed vertically downward, two CMP3 pyranometer (Kipp&Zonen, Netherlands) one upward, another downward. Observation height is 1.0 m, data logging by a Campbell CR850 logger. Sensor orientation：Observation mounting arm has 3 m long, parallel to roof edge, azimuth angle: 156° (East by south 66°)Observation Time:This site operates from 23 June, 2012 to 20 September, 2012. Observation data laagered by every 5 seconds uninterrupted. Output data contained sample data of every 5 seconds and mean data of 1 minute.Accessory data:Land surface (adobe roof) temperature, downward/upward total solar radiation, surface albedo. Dataset is stored in *.dat file, which can be read by Microsoft excel or other text processing software (UltraEdit, et. al). Table heads meaning: Rs_downwell, downward shortwave radiation (W/m^2); Rs_upwell, upward (reflect) shortwave radiation (W/m^2); albedo, calculate by Rs_upwell/ Rs_downwell. SBT_C, body temperature of SI-111 sensor (℃); Target_C, Target of surface temperature (℃). Dataset is stored day by day, named as: data format + site name + interval time + date + time. The detailed information about data item showed in data header introduction in dataset.

于2012年MUlti-Scale Observation EXperiment on Evapotranspiration over heterogeneous land surfaces 2012（MUSOEXE-12）的No.4涡度相关系统（EC4）边缘屋顶上，建立了一套陆地表面温度及向上/向下短波辐射观测系统。该观测站可提供TASI、WiDAS和L波段传感器在航空航天实验中的应用现场校准数据。观测站点位于张掖市小满乡石桥村一个大而均质化的土坯屋顶上，观测区域的陆地表面相对平坦且均匀，周围无高大树木。该站点距离西南方向的No.4涡度相关系统（EC4）观测点约20米。观测点的坐标为：北纬38°52′38.50″，东经100°21′27.00″。观测仪器：观测系统由一台垂直向下安装的SI-111红外辐射计（美国Campbell公司生产）、两台CMP3辐射计（荷兰Kipp&Zonen公司生产，一台向上，一台向下）组成。观测高度为1.0米，数据记录由Campbell CR850数据记录器完成。传感器方向：观测支架长3米，平行于屋顶边缘，方位角为156°（南偏东66°）。观测时间：该站点自2012年6月23日至9月20日运行。观测数据每5秒连续记录一次，输出数据包含每5秒的样本数据和每分钟的均值数据。附加数据：陆地表面（土坯屋顶）温度、向上/向下总太阳辐射、地表反照率。数据集存储为*.dat文件，可用Microsoft Excel或其他文本处理软件（如UltraEdit等）读取。表格头含义：Rs_downwell，向下短波辐射（W/m^2）；Rs_upwell，向上（反射）短波辐射（W/m^2）；albedo，由Rs_upwell/Rs_downwell计算得出。SBT_C，SI-111传感器的体温度（℃）；Target_C，地表温度目标（℃）。数据集按日存储，命名格式为：数据格式+站点名称+间隔时间+日期+时间。数据集中数据项的详细信息可在数据头介绍中查看。
