WebGreenness fraction from the North American Land Data Assimilation System (NLDAS) observations. Greenness is a measure of vegetation density that scientists use to model the carbon uptake of the land surface. Carbon uptake is important in understanding the carbon cycle and changes that might impact the global climate. Craig Pelissier, NASA/Goddard WebAug 1, 2014 · Abstract Global land-cover data are widely used in regional and global models because land cover influences land–atmosphere exchanges of water, energy, momentum, and carbon. Many models use data of maximum green vegetation fraction (MGVF) to describe vegetation abundance. MGVF products have been created in the past using …
