全球500m年植被生长状况指数数据集（2010-2020）

2010-2020年全球500m年植被生长状况指数数据集是基于全球年平均植被覆盖度（FVC）和年累计植被净初级生产力（NPP）产品进行生产的专题产品。针对FVC和NPP只能反映植被生长状况的一个方面，即生产能力或覆盖能力，难以准确反映植被生长状况的变化特征的问题，结合植被结构参量FVC和植被功能参量NPP两个指标的优势，生产了2010-2020年全球500m年植被生长状况指数产品，作为表征植被生长状况的综合专题产品。该数据集采用Sinusoidal投影，每景产品覆盖的经纬度范围为360°x150°，该数据集存储为*.tif 格式The Global 500m Annual Vegetation Growth Status Index Dataset spanning 2010 to 2020 is a thematic product developed based on global annual average Fraction of Vegetation Cover (FVC) and annual cumulative Net Primary Productivity (NPP) products. To address the limitation that FVC and NPP can only reflect one single aspect of vegetation growth status, namely productivity or coverage capacity, and fail to accurately depict the changing characteristics of vegetation growth, this dataset was produced by integrating the respective advantages of the vegetation structural parameter FVC and vegetation functional parameter NPP, serving as a comprehensive thematic product for characterizing vegetation growth status. This dataset adopts the Sinusoidal projection, with each individual scene covering a spatial extent of 360° × 150° in longitude and latitude, and is stored in the *.tif format.
