Vegetation point-intercept (VPI) any-hit cover metric data were combined with Landsat imagery to develop fractional maps of any-hit cover for four aggregated plant functional types (PFTs); shrubs bryophytes, lichen, and herbs for the upland tundra area of the Y-K Delta, Alaska. VPI data were collected from plots in areas burned in 1971, 1985, 2005, and 2015.
Ecological field data and maps of vegetation cover spanning gradients of fire history in upland tundra are available from the Arctic-Boreal Vulnerability Experiment (ABoVE).
Each black dot on this digital elevation map (DEM) represents a surface weather station in continental North America providing Daymet data in 2010. Additional stations providing Daymet data are located in Puerto Rico and Hawaii.
Daymet derived annual average of daily minimum temperature, 1980 (left) and 2019 (right), for a subset of North America. Images are scaled from -20 to +20 degrees C.
Study area included sites burned in 2014 and 2015 in the southeastern portion of the Northwest Territories and northern Alberta of Canada. The study area includes all 2014 and 2015 fires within a radius of approximately 300 km from Great Slave Lake.
Pre- and post-fire Landsat images were used to classify burn severity of soil organic matter across portions of arctic Canada.
AirMOSS radar swaths flown in 2014 and 2015 in Alaska. In situ soil moisture and temperature profile measurements were obtained at the CALM (Circumpolar Active Layer Monitoring) and the UAF GIPL (Geophysical Institute Permafrost Laboratory, University of Alaska Fairbanks) sites and used to validate AirMOSS data products.
Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) radar data from Alaska are used to derive estimates of active layer thickness. Data from flights in 2014 and 2015 are now available.
