HiWATER: Dataset of sun photometer observations in the middle and upper reaches of the Heihe River Basin (2012)

The object of this dataset is to support the atmospheric correction data for the satellite and airborne remote-sensing. It provides the atmospheric aerosol and the column content of water vapor. The dataset is sectioned into two parts: the conventional observations data and the observations data synchronized with the airborne experiments. The instrument was on the roof of the 7# in the Wuxing Jiayuan community from 1 to 24 in June. After 25 June, it was moved to the ditch in the south of the Supperstaiton 15. The dataset provide the raw observations data and the retrieval data which contains the atmosphere aerosol optical depth (AOD) of the wavebands at the center of 1640 nm, 1020 nm, 936 nm, 870 nm, 670 nm, 500 nm, 440 nm, 380 nm and 340 nm, respectively, and the water vapor content is retrieved from the band data with a centroid wavelength of 936 nm. The continuous data was obtained from the 1 June to 20 September in 2012 with a one minute temporal resolution. The time used in this dataset is in UTC+8 Time.Instrument:The sun photometer is employed to measure the character of atmosphere. In HiWATER, the CE318-NE was used.

本数据集旨在为卫星及航空遥感大气校正提供支持，其中包含了大气气溶胶及其水汽柱含量。该数据集分为两部分：传统观测数据与与航空实验同步的观测数据。仪器设于吴兴嘉园社区7号楼屋顶，观测时间自六月一日至二十四日。自六月二十五日起，仪器移至超级站南侧的沟渠。数据集提供了原始观测数据以及检索数据，包括在1640 nm、1020 nm、936 nm、870 nm、670 nm、500 nm、440 nm、380 nm和340 nm波段的气溶胶光学厚度（AOD），以及通过936 nm中心波长的波段数据获取的水汽含量。连续数据自2012年6月1日至9月20日获取，时间分辨率为一分钟。本数据集使用的时间为UTC+8时区。仪器：采用太阳光度计测量大气特性。在HiWATER项目中，使用了CE318-NE型号。
