Data
National DWM field data (actual measurement variables without population estimates) are currently available at this location as comma delimited files.
http://www.fia.fs.fed.us/tools-data/data/. FIADB snapshot download files for selected states are available at: http://www.ncrs2.fs.fed.us/FIADatamart/fiadatamart.aspx
The field data is organized according to a national data management standard (NIMS) that describes each table and field in adequate detail for interpretation and analysis.

Both population and plot-level DWM attributes estimates (e.g., fuel loadings) will be available in the near future as the programming of a national estimation engine is currently underway. Stay tuned for more information!
