This EnviroAtlas dataset includes the sum of aboveground live dry biomass estimate by 12-digit Hydrologic Unit (HUC) in total metric tons (megagrams) from the 2000 National Biomass and Carbon Dataset (Version 2.0) developed by the Woods Hole Research Center and released in October 2012. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).
This dataset is useful for evaluating the potential value of ecosystem services provided by vegetation communities. The overall goal of EnviroAtlas is to employ and develop the best available science to map indicators of ecosystem services production, demand, and drivers for the nation.

Entity and Attribute Information
Entity and Attribute Overview: These metrics describe the amount of carbon stored in the aboveground biomass of forests. The metric was generated using ArcMap 10.4 in conjunction with National Biomass and Carbon Dataset for the year 2000 v2 (NBCD2000) released in October of 2012. The NBCD dataset is a high-resolution (30 m), year-2000 baseline estimate of basal area-weighted canopy height, aboveground live dry biomass, and standing carbon stock for the conterminous United States. For EnviroAtlas, the NBCD 30 m resolution data were aggregated to the 12-digit HUC level. For more information on the metric calculation, please see the Woods Hole Research Center Internet site.

Extract and mosaic all 66 30m biomass rasters to a single raster
2017-06-13T00:00:00
Using National Land Cover Database (NLCD) 2011 grid, set areas of "VALUE" = 0 to NULL using Set Null tool using combined raster as false raster input
2017-06-13T00:00:00
Execute Zonal statistics as table, using HUC12 as zones to summarize raster with SUM as the statistics type. (Cell values are mean biomass in kg/m2, multiplied by ten to preserve significant digits.) Divide the sum by 10. The result is the sum of the mean kg/m2 for the HUC12.
2017-06-13T00:00:00
Multiply the sum by 900 to convert from the summed mean kg/m2 to the total kg for the HUC12 (original raster values were means in kg/m2 for 900 square meter cells).
2017-07-20T00:00:00
Divide by 1000 to convert to metric tons (megagrams).
