This NDVI dataset is the latest NOAA Global Inventory Monitoring and Modeling System (GIMMS) long time series (1981-2015) NDVI product, version number 3g v1。 In order to remove the noise in NDVI data, the maximum synthesis and multi-sensor contrast correction are carried out. The time resolution of the product is twice a month, the spatial resolution is 8km, and the data format is geotiff. The time span is from July 1981 to December 2015. This data set is widely used in the analysis of long-term change trend of vegetation. The data set cuts the upper of the Yangtze River in China from the global data set, so as to carry out research and analysis on the upper of the Yangtze River separately.
Data naming format: GIMMS NDVI3g v1 CJSY yyyy mm, where yyyy represents year and mm represents month
Data usage: This dataset can be directly opened with ArcGIS, and the data scale is converted to 10000.
