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> Data Format:<\/span><\/span> Raster data are continuous; <\/span><\/span><\/p> Units: <\/span><\/span>Fahrenheit<\/span><\/span><\/p> Spatial Resolution:<\/span><\/span> 4000m (4km)<\/span><\/span><\/p> Source data:<\/span><\/span> <\/span><\/span>PRISM<\/span><\/span><\/a><\/p> Additional Resources:<\/span><\/span><\/p> Details on <\/span><\/span>Method Changes and Source Data Versions<\/span><\/span><\/a><\/p> Overview of the Terrestrial Condition Assessment: <\/span><\/span>TCA Hubsite<\/span><\/span><\/a> or <\/span><\/span>Landfire Office Hour Presentation<\/span><\/span><\/a><\/p>
