Datasets description

  This dataset contains phenological camera observation data of the Huazhaizi station in the midstream reaches of the Heihe integrated observatory network from May 10 to September 30 in 2025. The site (100.3201° E, 38.7659° N) was located in the Zhangye City in Gansu Province. The elevation is 1731 m. The phenology camera pictures were stored two-hour intervals from 7:00 to 19:00. 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.
