Forest stand age map of Canada (2011) and the United States (2006 & 2011)

This data publication contains an update for the 2006 Continental United States (CONUS) and Alaska to the first continental forest stand age map of North America. A new map for 2011 covering Alaska, CONUS and Canada has been produced. It was made by combining forest inventory data, historical fire data, optical satellite data and other disturbance/forest change products that have become available after the original product was published. A companion map of the standard deviations for age estimates, developed for quantifying uncertainty, is also included.The forest stand age data can be used in large-scale carbon modeling, both for land-based biogeochemistry models and atmosphere-based inversion models, in order to improve the spatial accuracy of carbon cycle simulations.This product is an updated version of Pan et al. (2014). Original metadata date was 11/06/2015. Minor metadata updates on 12/15/2016 and 07/02/2019.
