黑河综合遥感联合试验：临泽站加密观测区地表反照率观测数据集

2008年5月28日至7月4日在临泽站加密观测区的荒漠过渡带和临泽站内开展反照率观测。观测样方和目标：荒漠南北样带A9样方边和LY07号样方边（纯沙，沙生植物，干死的一年生草本），临泽站内（胡麻，玉米，西红柿）。观测仪器：KippZonen CMP3短波表（上表编号为071391，下表编号为071390），测量波谱范围：310nm-2800nm。记录方式：5月28日至6月22日期间用深圳优利德（UNIT）UT58万用表以手工方法记录向上和向下的电压值，预处理时将其换算为向上和向下辐照度，在计算反照率，记录间隔为2分钟；6月25日至7月4日用美国Campbell CR1000数采自动记录，记录间隔为1秒钟。自记观测数据文件包含以下信息：TIMESTAMP（观测时间）、SOLAR_UP_AVG（下行短波辐射，由向上辐射表测得）、SOLAR_DOWN_AVG（上行短波辐射，由向下辐射表测得）、SOLAR_NET_AVG（净辐射）= SOLAR_UP_AVG - SOLAR_DOWN_AVG、albedo_Avg（反照率） = SOLAR_DOWN_AVG / SOLAR_UP_AVG、batt_volt_Min（电瓶电压），ptemp（CR1000面板温度）。短波表架设高度：两个表离地面1m左右，水准泡调平。数据存储：手工记录数据为Excel表格，自记数据为.dat文件，处理后数据保存在Excel表格中，原始数据中包括观测点的照片。观测时间：2008年5月28日，6月5日，6月6日，6月15日，6月22日，6月25日，6月30日，7月4日。

Albedo observations were conducted in the desert ecotone of the Linze Station intensive observation area and within the Linze Station from May 28 to July 4, 2008.
Observation plots and targets: The edges of the north-south desert transect Plot A9 and Plot LY07 (pure sand, psammophytes, dead annual herbs), and cultivated plots within Linze Station (flax, maize, tomato).
Observation instruments: KippZonen CMP3 shortwave radiometers (upper instrument serial number: 071391, lower instrument serial number: 071390), with a measured spectral range of 310 nm to 2800 nm.
Recording method: From May 28 to June 22, upward and downward voltage values were manually recorded using a Shenzhen UNI-T UT58 multimeter. During preprocessing, these voltage values were converted to upward and downward irradiance, which were then used to calculate albedo, with a recording interval of 2 minutes. From June 25 to July 4, automatic recording was performed using a Campbell CR1000 data logger from the United States, with a recording interval of 1 second.
The self-recording observation data file contains the following variables: TIMESTAMP (observation time), SOLAR_UP_AVG (downward shortwave radiation measured by the upward radiometer), SOLAR_DOWN_AVG (upward shortwave radiation measured by the downward radiometer), SOLAR_NET_AVG (net radiation) = SOLAR_UP_AVG - SOLAR_DOWN_AVG, albedo_Avg (albedo) = SOLAR_DOWN_AVG / SOLAR_UP_AVG, batt_volt_Min (battery voltage), and ptemp (CR1000 panel temperature).
Installation height of the shortwave radiometers: Both instruments were installed approximately 1 meter above the ground surface, and leveled using the built-in spirit level.
Data storage: Manually recorded data was stored in Excel spreadsheets; self-recording raw data was saved in .dat files; processed datasets were stored in Excel spreadsheets. The original dataset includes photographs of the observation sites.
Observation dates: May 28, June 5, June 6, June 15, June 22, June 25, June 30, and July 4, 2008.
