Alaska Arctic Floristic Provinces Map
The Arctic has a relatively consistent core ofplant species that occur throughout the circumpolar region, but there is also considerable east to west variation in regional... -
Circumpolar Arctic Lake Cover Map
Lake cover strongly affects the reflectance of the land surface over large areas of the Arctic, and was useful for identifying extensive wetlands. Lake cover was based on the... -
Alaska Arctic Landscape Map
The landscape physiography map displays regions of plains, hills, mountains, glaciers and lakes. Generally, plains are flat or gently rolling landscapes less than 200 m above... -

CANADIAN TRANSECT FOR THE CIRCUMPOLAR ARCTIC VEGETATION MAP (1999)
Variations in vegetation cover and species composition related to climate are evident from the southern to northern Arctic. Scientists involved in the Circumpolar Arctic... -
Circumpolar Arctic Biomass Trend 1982-2010 (Epstein et al. 2012)
Trend in Arctic biomass was calculated from a linear regression of biomass values for all years 1982-2010 (Epstein et al 2012). Pixels with significant trends (p < 0.05) were... -
Circumpolar Arctic AVHRR Summer Warmth Index 1982-2003 (Raynolds et al. 2008)
This data set was calculated from monthly AVHRR thermal infrared data (Comiso 2003). Summer Warmth Index (SWI) is the sum of monthly mean temperatures above 0 degrees Celsius.... -
Circumpolar Arctic Biomass (Raynolds et al 2012)
This map portrays an estimate of above ground plant biomass for the tundra biome based on trans-Arctic field data and AVHRR NDVI (Raynolds et al. 2012). Aboveground phytomass... -

Advanced Very High Resolution Radiometer (AVHRR) data were obtained from the USGS Global AVHRR 10-day composite data (http://edcdaac.usgs.gov/1KM/1kmhomepage.asp) (Markon et al.... -
Circumpolar Arctic Floristic Provinces Map
Floristic sectors characterize the considerable east-west floristic variation within the subzones. The more northern Arctic bioclimate subzones have a relatively consistent core... -
Alaska Arctic Tundra Vegetation Map (Raynolds et al. 2006)
The Alaska Arctic Tundra Vegetation Map (AATVM) is a geoecological map of the Arctic Tundra within Alaska. It includes areas north and west of the forest boundary and excludes... -
Alaska Arctic Lake Cover Map
Lake cover strongly affects the reflectance of the land surface over large areas of Alaska, and was useful for identifying extensive wetlands. Lake cover was based on the number... -
