MODIS/Terra Vegetation Indices 16-Day L3 Global 250m SIN Grid V061

The Terra Moderate Resolution Imaging Spectroradiometer (MODIS) Vegetation Indices (MOD13Q1) Version 6.1 data are generated every 16 days at 250 meter (m) spatial resolution as a Level 3 product. The MOD13Q1 product provides two primary vegetation layers. The first is the Normalized Difference Vegetation Index (NDVI) which is referred to as the continuity index to the existing National Oceanic and Atmospheric Administration-Advanced Very High Resolution Radiometer (NOAA-AVHRR) derived NDVI. The second vegetation layer is the Enhanced Vegetation Index (EVI), which has improved sensitivity over high biomass regions. The algorithm chooses the best available pixel value from all the acquisitions from the 16 day period. The cri...

Terra中等分辨率成像光谱辐射计（Moderate Resolution Imaging Spectroradiometer，MODIS）植被指数（MOD13Q1）6.1版数据集为三级产品，以250米空间分辨率每16天生成一次。该产品包含两类核心植被指数图层：第一类为归一化差分植被指数（Normalized Difference Vegetation Index，NDVI），可作为现有美国国家海洋和大气管理局-先进甚高分辨率辐射计（National Oceanic and Atmospheric Administration-Advanced Very High Resolution Radiometer，NOAA-AVHRR）反演所得归一化差分植被指数的连续性接续指标；第二类为增强型植被指数（Enhanced Vegetation Index，EVI），其在高生物量区域具备更优异的探测灵敏度。该算法会从16天观测周期内的所有有效观测数据中选取最优像素值。The cri...
