Dataset for intercomparison of Sen4GPP GPP products at fluxtower sites

This dataset provides the estimation of various gross primary productivity (GPP) products made within the Sen4GPP project at eddy covariance flux tower sites. These cover about the time range from "2018-05-04" to "2020-12-29" with an 8-daily frequency. There are 3 types or categories of products (LUE, SIF and ML) based on the 3 different approaches used in the Sen4GPP project to estimate GPP. For more information please refer to the respective ATBD and PVR documents of the Sen4GPP project.

本数据集提供了Sen4GPP项目针对涡度协方差通量塔站点生成的多款总初级生产力（gross primary productivity, GPP）估算产品。该数据集的时间覆盖范围约为2018年5月4日至2020年12月29日，时间分辨率为8天。数据集包含三类估算产品（LUE、SIF与ML），对应Sen4GPP项目中用于总初级生产力估算的三种不同技术路径。如需获取更多详细信息，请参阅Sen4GPP项目对应的ATBD与PVR文档。
