青藏高原植被指数数据（2000-2018）

本数据集是2000-2018年青藏高原地区归一化植被指数的年内最大值数据（NDVI-AM）。数据为栅格TIFF格式，空间分辨率为250米，栅格数据值域为[-1,1]。可用于青藏高原植被覆盖度变化、草地退化等生态环境变化的研究，也可以为城镇化与生态环境交互胁迫研究提供数据支持。该数据是基于MODIS中分辨传感器MOD13系列的陆地2级标准数据产品计算的（https://modis.gsfc.nasa.gov/data/dataprod/mod13.php）。该2级产品数据是对原始的MODIS原始数据集进行加工后生成的特定应用数据产品。NDVI-AM数据根据其中的归一化植被指数珊格数据，计算每个像元NDVI的年内最大值而加工生成的。

This dataset is the annual maximum normalized difference vegetation index (NDVI-AM) data over the Qinghai-Tibet Plateau from 2000 to 2018. The data is stored in raster TIFF format, with a spatial resolution of 250 meters, and the value range of the raster data is [-1, 1]. This dataset can be employed for studies on ecological environmental changes such as vegetation coverage variation and grassland degradation over the Qinghai-Tibet Plateau, and can also provide data support for research on the interactive stress between urbanization and the ecological environment. This dataset was derived from the standard Level-2 land data products of the MOD13 series from the MODIS moderate-resolution sensor (https://modis.gsfc.nasa.gov/data/dataprod/mod13.php). These Level-2 products are targeted application data products generated by processing the raw MODIS dataset. The NDVI-AM data is produced by calculating the annual maximum NDVI value for each pixel using the normalized difference vegetation index raster data from the MOD13 Level-2 products.
