Terrestrial Condition Assessment (TCA) Alaska Climate Exposure Temperature (Image Service)

<div><div><div><p><a href="https://data.fs.usda.gov/geodata/rastergateway/TCA/Alaska/04_Climate/TCA_AK_Temperature_Exposure.zip">Direct Download (Raster Data Gateway)</a></p><p>Objective: Characterize climate departures for the most recent 5 years as compared with the historical record, identifying locations where recent conditions indicate a significant change from the historical baseline.</p><p>Data: Gridded coverages based on DAYMET climate data were used to calculate departure of mean temperature in winter (Dec. – Feb.), spring (Mar. – May), summer (Jun. – Aug.), and fall (Sep. – Nov.) for the recent 5-year period as compared with previous years in the historical record. 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 DAYMET data and the TCA Assessment year, for example, the 2024 TCA Assessment used 2019-2023 data for the most recent time period, and 1980-2018 data for the historical baseline.</p><p>Data Format: Raster data are continuous; </p><p>Units: Fahrenheit</p><p>Spatial Resolution: 1000m (1km)</p><p>Source data: <a href="https://daac.ornl.gov/DAYMET/guides/Daymet_Daily_V4.html">DAYMET</a></p><p>Additional Resources:</p><p>Details on <a href="https://usfs.box.com/s/79vx1b42xg8u6ivjombxjes36nzfhgml">Method Changes and Source Data Versions</a></p><p>Overview of the Terrestrial Condition Assessment: <a href="https://terrestrial-condition-assessment-usfs.hub.arcgis.com/">TCA Hubsite</a> or <a href="https://www.youtube.com/watch?v=Kf0P3cAq1rs&list=PLwRbAc4x5n94rLca1CXXuugtRDt_G666M&index=19">Landfire Office Hour Presentation</a></p><p>Explore the results of the most recent assessment: <a href="https://apps.fs.usda.gov/gtac-toolsms/tca/">TCA Interactive Data Viewer</a></p><p>Learn more about the TCA KPI: <a href="https://cxodashboard.dl.usda.gov/t/NRE/views/EcologicalConditionOutcomes_17531128629260/EcologicalOutcomes">TCA Dashboard</a></p><p>*if you have trouble viewing the Dashboard, please submit a <a href="https://usdagcc.sharepoint.com/sites/fs-wo-cdoc/SitePages/Dashboards.aspx">Tableau Viewer Access Request</a></p></div></div></div><div><br>This record was taken from the USDA Enterprise Data Inventory that feeds into the <a href="https://data.gov">https://data.gov</a> catalog.
