A consistent, 2‐decade or longer vegetation record is needed to detect trends in global land cover and climate change. With the longest record starting in 1981, vegetation data from the Advanced Very High Resolution Radiometer (AVHRR) have played a key role in detecting changes in vegetation caused by global temperature increases. NASA's Global Inventory Modeling and Mapping Studies (GIMMS) group has recently produced a new global vegetation data set at 8‐km resolution from 1981 to 2004. Maximizing the length, stability, and quality of the AVHRR data set, the GIMMS Normalized Difference Vegetation Index (NDVI) data will enable new Earth science conclusions and continuous monitoring of vegetation dynamics during the next decade.
