NOAA Climate Data Record Normalized Difference Vegetation Index: 1981-2013

National Oceanic and Atmospheric Administration (NOAA) Climate Data Records (CDR) provide historical climate information using data from weather satellites. This dataset contains daily Normalized Difference Vegetation Index (NDVI) derived from surface reflectance data acquired by the Advanced Very High Resolution Radiometer (AVHRR) sensor. This long-term record spans from 1981 to 2013 and utilizes AVHRR data from seven NOAA polar orbiting satellites: NOAA 7, 9, 11, 14, 16, and 18. This NDVI collection provides the global change and resource management communities with vegetation data for historical trend analysis and vegetation monitoring studies for land surfaces around the globe.

美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）气候数据记录（Climate Data Records，CDR）依托气象卫星数据提供历史气候信息。本数据集包含由甚高分辨率辐射计（Advanced Very High Resolution Radiometer，AVHRR）传感器获取的地表反射率数据衍生得到的每日归一化差异植被指数（Normalized Difference Vegetation Index，NDVI）。该长期观测序列的时间跨度为1981年至2013年，所用AVHRR数据来自7颗NOAA极轨卫星：NOAA 7、9、11、14、16及18。这套NDVI数据集可为全球变化与资源管理领域提供全球陆面植被数据，用于历史趋势分析及植被监测相关研究。
