2000-2016年中国500m 基于VPM模型的生态系统总初级生产力GPP时空连续数据

本数据集为长时间序列（2000-2016）中国范围内的总初级生产力（gross primary productivity，GPP）产品数据。基于EVI、LSWI等遥感数据及气温、降水、辐射等气象数据，利用光能利用率VPM模型计算得到，数据空间分辨率为500m，时间分辨率为8天，格式为GeoTIFF格式的栅格数据。

This dataset is a long-time series (2000–2016) gross primary productivity (GPP) product covering mainland China. It was calculated using the Vegetation Photosynthesis Model (VPM), a light use efficiency model, based on remote sensing data including EVI, LSWI and other relevant remote sensing products, as well as meteorological data such as air temperature, precipitation and solar radiation. The dataset has a spatial resolution of 500 meters, a temporal resolution of 8 days, and is stored as GeoTIFF-format raster data.
