黑河流域地表过程综合观测网：大满超级站物候相机观测数据集（2022）

该数据集包含2022年5月15日至10月31日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。物候相机集成数据获取与数据传输功能。该物候相机可指定拍摄时间频率。对于绿度指数物候期计算，需要根据感兴趣区域计算相对绿度指数（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），然后进行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。本数据集为相对绿度指数（Gcc）。

This dataset contains phenocamera observation data collected at the Daman Super Station in the middle reaches of the Heihe River Basin Comprehensive Observation Network for Earth Surface Processes from May 15 to October 31, 2022. The phenocamera integrates data acquisition and data transmission functions, and supports configurable shooting frequency. For phenology calculation based on greenness indices, the relative green chromatic coordinate (GCC, Green Chromatic Coordinate, defined by the formula GCC = G/(R+G+B), where R, G, and B are the pixel values of the red, green, and blue channels of the captured image, respectively) must be first computed based on the Region of Interest (ROI). Subsequently, invalid value imputation, filtering and smoothing are conducted, and key phenological parameters including the start date, peak date, and end date of the growing season are finally determined through growth curve fitting. This dataset provides relative green chromatic coordinate (GCC) data.
