该数据集包含了2025年5月1日至2025年9月30日的黑河流域地表过程综合观测网中游大满超级站的物候相机观测数据。站点位于甘肃省张掖市大满灌区内，下垫面是玉米。观测点的经纬度是100.37223E, 38.85551N，海拔1556.06m。站点拍摄物候图片自6:00至20:00，每2小时拍摄一次。对于物候期的计算，首先，根据感兴趣区计算物候指标，如相对绿度指数(GCC, Green Chromatic Coordinate公式为GCC=G/(R+G+B), R、G、B为图像红、绿、蓝三通道像元值)。然后对数据进行质量控制、无效值填充和滤波平滑。最后根据生长曲线拟合确定关键物候期参数，如生长季起始日、顶峰、生长季结束日等。本数据集为该站点2025年物候图片。\n

This dataset contains phenological camera observation data of the Daman Superstation in the middle reaches of Heihe integrated observatory network from May 1 to September 30 in 2025. The site (100.37223° E, 38.85551° N) was located in the Zhangye City in Gansu Province. The elevation is 1556.06 m. The phenology camera pictures were stored two-hour intervals from 6:00 to 20:00. For the calculation of the phenology, firstly, the phenological index needs to be calculated according to the region of interest. Such as, the relative greenness index (GCC, Green Chromatic Coordinate, calculated by GCC=G/(R+G+B)). Then, controlling the quality of data, filling the invalid value and filtering smoothing are performed. Finally, the key phenological parameters are determined according to the growth curve fitting, such as the growth season start date, peak, growth season end, etc. This data set includes the phenology camera pictures in 2025.\r\n
