Pre-Fire Ecosystem Classifications in Burned Area

Great Slave Lake

Ecosystem map for the Great Slave Lake area, Northwest Territories, Canada, for the period 1997-2011.

ABoVE researchers compiled a map of ecosystem states prior to the 2014 & 2015 fires in the Northwest Territories, Canada.

Long-term Climate Normals for Alaska

Annual Average Maximum Temperature for Alaska

30-year annual average maximum temperature for Alaska at 60-m resolution for (a) the last glacial maximum period ~18,000 years ago and (b) the modern period 1975-2005.

A new dataset provides 30-year climate 'normals' for the last glacial maximum (~18,000 years ago) and the present day in Alaska.

Subsistence Use Areas in Alaska

Subsistence Resource Use Areas

Combined map of subsistence resource use areas of Interior Alaskan communities with (1) points marking harvest effort locations, (2) polygons indicating harvest effort areas, and (3) lines indicating linear harvesting activity.

Maps of the search and harvest areas used by residents of Interior Alaska are available.

Tracking Permafrost with P-band SAR

AirMOSS Radar Swaths

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.

Vegetation Imagery from Toolik Lake, Alaska

Toolik plot photo.

A plot photo (#0656) taken at the largest study area "Toolik" at elevation 765.7 m. The small white object was included in many of the photos as a color reference. The photographer's boots are also often visible, in this photo they are to the lower left of the white object.

A new ABoVE dataset offers hundreds of ground-based vegetation photos which may serve as a reference for studies of climate and vegetation change in the area.
