塞罕坝站全球变化参数观测数据集(2022-2025)

该数据集为承德遥感实验站（位于河北省塞罕坝机械林场内，简称塞罕坝站)2022-2025年全球变化参数观测数据集。数据集包含20种参数及部分参数的质控参数，根据参数时间频率和数据特征分存于三个数据文件，分别为“反照率、地表净辐射、下行短波辐射、上行短波辐射、下行长波辐射、上行长波辐射、光合有效辐射、光合有效辐射吸收比例、地表温度、土壤温度、土壤水分、总初级生产力、蒸散发”一组，数据时频30分钟；“叶绿素荧光、归一化植被指数、地表反射率”一组，时频30分钟；“叶面积指数、聚集指数、植被覆盖度和叶绿素浓度”一组，时频每日。数据集由原位观测数据经过异常值剔除、插补、质量分级等处理后得到。（协议共享）

This dataset is the 2022–2025 global change parameter observation dataset of Chengde Remote Sensing Experimental Station, which is located within the Saihanba Mechanized Forest Farm of Hebei Province and abbreviated as Saihanba Station. The dataset contains 20 types of parameters and quality control parameters for some of these parameters. It is stored in three data files based on the temporal frequency and data characteristics of the parameters: the first group including Albedo, Net Surface Radiation, Downward Shortwave Radiation, Upward Shortwave Radiation, Downward Longwave Radiation, Upward Longwave Radiation, Photosynthetically Active Radiation (PAR), Fraction of Absorbed Photosynthetically Active Radiation (fAPAR), Land Surface Temperature (LST), Soil Temperature, Soil Moisture, Gross Primary Productivity (GPP) and Evapotranspiration, with a 30-minute temporal resolution; the second group including Chlorophyll Fluorescence, Normalized Difference Vegetation Index (NDVI) and Land Surface Reflectance, with a 30-minute temporal resolution; the third group including Leaf Area Index (LAI), Clumping Index, Fraction of Vegetation Cover (FVC) and Chlorophyll Concentration, with a daily temporal resolution. The dataset is derived from in-situ observation data after processing including outlier removal, imputation and quality grading. (Shared under protocol)
