Forest stand age map of Canada (2004) and the United States (2006)

This data publication contains the first continental forest stand age map of North America by combining forest inventory data, historical fire data, optical satellite data and the dataset from NASA's Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) project. Raster maps represent 2006 stand age at 1 kilometer resolution for Alaska, the conterminous United States, and each forest region. There is also a 2004 stand age map for Canada. 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.Original metadata date was 10/28/2014. Minor metadata updates on 12/14/2016 and 07/25/2019.
