2013年-2017年中国观测站（张掖站和怀来站）玉米生长季反射率数据集

本数据集的测量地点包括甘肃省临泽兰大草地站和张掖市沙井镇兰大西部草业试验站及附近、中国科学院怀来遥感综合试验站，观测时间为2013年-2017年，对不同作物的各个生长阶段进行反射率及配套参数测量。数据内容包括反射率、测量时间、经纬度、测量高度、测量次数、测量人、预处理人、审核人、日光情况、云量、太阳天顶角、方位角、观测角度等。数据集共128条记录。

This dataset was collected at multiple field sites: the Lanzhou University Grassland Station in Linze, Gansu Province, the Lanzhou University Western Grassland Industry Experimental Station and its vicinity in Shajing Town, Zhangye City, and the Huailai Remote Sensing Comprehensive Experimental Station of the Chinese Academy of Sciences. Observations were conducted between 2013 and 2017, with measurements of reflectance and associated supporting parameters taken at various growth stages of different crops. The dataset includes the following items: reflectance, measurement time, geographic coordinates (longitude and latitude), measurement height, number of measurement trials, operator, preprocessor, reviewer, solar conditions, cloud cover, solar zenith angle, azimuth angle, and observation angle, among others. In total, this dataset contains 128 records.
