BOREAS FOLLOW-ON DSP-10 REGRIDDED NDVI MAPS FOR 1994

These images were produced by averaging the 1-km FASIR-NDVI maps by Jing Chen to a 10' (horizontal) by 5' (vertical) pixel size in a straight latitude/longitude grid. Each pixel represents the average NDVI of the 1-km pixels that fall in each 10' by 5' pixel, where more than 50% of the 1-km pixels in the 10' by 5' area are not cloud and are not missing. If more than 50% of the 1-km pixels are missing or cloudy, a value of 0 is assigned to the 10' by 5' pixel.本数据集图像由陈静（Jing Chen）生成，通过将1公里分辨率的FASIR-NDVI（FASIR归一化差分植被指数）地图在规整经纬度网格下重采样为10′（水平）×5′（垂直）的像元尺寸。每个10′×5′像元的数值为其覆盖范围内所有落入该像元的1公里像元的NDVI均值，筛选条件为该区域内超过50%的1公里像元无云且无数据缺失。若该区域内超过50%的1公里像元存在数据缺失或被云覆盖，则该10′×5′像元将被赋值为0。
