Service Description: The USDA FIA Carbon Pools image service was developed using data from over 213,000 national forest inventory plots measured during the period 2014-2018 from the USFS Forest Inventory and Analysis (FIA) program, in conjunction with other auxiliary information. Roughly 4,900 Landsat 8 OLI scenes, collected during the same time period, were processed to extract information about vegetation phenology. This information, along with climatic and topographic raster data, were used in an ecological ordination model of tree species. The model produced a feature space of ecological gradients that was then used to impute FIA plots to pixels. The plots imputed to each pixel were then used to assign values (tons per pixel) for each of the forest carbon pools that FIA tracks: live tree (aboveground), live tree (belowground), down dead, litter, soil organic, standing dead, understory (aboveground), and understory (belowground). The sum of these pools is total forest carbon. This information taken from https://fia-usfs.hub.arcgis.com/
