Data were summarized at the Subsection scale of the USFS National Hierarchy of Ecological Units and applied to the corresponding landscape (LTA). There is a one-year lag between the most recent available PRISM data and the TCA Assessment year, for example, the 2024 TCA Assessment used 2019-2023 data for the most recent time period, and 1900-2018 data for the historical baseline.</span></span></p><p style='margin:0 0 11 0;'><span style='font-weight:bold;'><span>Data Format:</span></span><span><span> Raster data are continuous; </span></span></p><p style='margin:0 0 11 0;'><span style='font-weight:bold;'><span>Units: </span></span><span><span>Fahrenheit</span></span></p><p style='margin:0 0 11 0;'><span style='font-weight:bold;'><span>Spatial Resolution:</span></span><span><span> 4000m (4km)</span></span></p><p style='margin:0 0 11 0;'><span style='font-weight:bold;'><span>Source data:</span></span><span><span> </span></span><a href='http://www.prism.oregonstate.edu/' style='text-decoration:underline;'><span style='text-decoration:underline;'><span>PRISM</span></span></a></p><p style='font-weight:bold;margin:0 0 11 0;'><span><span>Additional Resources:</span></span></p><p style='margin:0 0 11 0;'><span><span>Details on </span></span><a href='https://usfs.box.com/s/79vx1b42xg8u6ivjombxjes36nzfhgml' style='text-decoration:underline;'><span style='text-decoration:underline;'><span>Method Changes and Source Data Versions</span></span></a></p><p style='margin:0 0 11 0;'><span><span>Overview of the Terrestrial Condition Assessment: </span></span><a href='https://terrestrial-condition-assessment-usfs.hub.arcgis.com/' style='text-decoration:underline;'><span style='text-decoration:underline;'><span>TCA Hubsite</span></span></a><span><span> or </span></span><a href='https://www.youtube.com/watch?v=Kf0P3cAq1rs&amp;list=PLwRbAc4x5n94rLca1CXXuugtRDt_G666M&amp;index=19' style='text-decoration:underline;'><span style='text-decoration:underline;'><span>Landfire Office Hour Presentation</span></span></a></p><p style='margin:0 0 11 0;'><span><span>Explore the results of the most recent assessment: </span></span><a href='https://apps.fs.usda.gov/gtac-toolsms/tca/' style='text-decoration:underline;'><span style='text-decoration:underline;'><span>TCA Interactive Data Viewer</span></span></a></p><p><span><span>Learn more about the TCA KPI: Dashboard link when available</span></span></p></div></div></div>
