2009-2020年中国30m植被指数逐旬产品

数据集包括2009-2020年30m中国植被指数逐旬产品。数据包括增强植被指数EVI和质量控制波段EVIqc，归一化植被指数NDVI和质量控制波段NDVIqc。产品使用环境（HJ-1 CCD）卫星数据和高分一号宽幅相机（GF-1 WFV）卫星数据，以平均合成算法（MC）作为主算法，以反射率波段直接计算法（VI）作为备用算法，进行中国NDVI合成产品生产。

This dataset contains 30-meter spatial resolution 10-day composite vegetation index products of China spanning from 2009 to 2020. The dataset includes Enhanced Vegetation Index (EVI) and its corresponding quality control band EVIqc, as well as Normalized Difference Vegetation Index (NDVI) and its corresponding quality control band NDVIqc. These products were generated using data from the HJ-1 CCD and GF-1 Wide Field View (WFV) satellites, with the Mean Composite (MC) algorithm serving as the primary production method and the direct reflectance band calculation method (VI) as the backup algorithm for manufacturing China's composite vegetation index products.
