Circumpolar Arctic AVHRR Summer Warmth Index 1982-2003 (Raynolds et al. 2008)

Aga circumpolar avhrr swi 1982 2003 Alaska Geobotany Center (AGC) - 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. The months of May-September were evaluated for the years 1982 - 2003 (Raynolds et al. 2008).

Alaska Arctic Landscape Map

Aga arctic ak landscape 2005 Alaska Geobotany Center (AGC) - 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 sea level. Hills are more dissected than plains (more surface roughness) and are 200-500 m in elevation. Mountains have greater surface roughness and are above 500 m in elevation. The Alaska Arctic Tundra Vegetation Map is...

Circumpolar Arctic AVHRR False Color-Infrared (CIR) Map

Aga circumpolar avhrr cir 1995 Alaska Geobotany Center (AGC) - 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. 1995). Glaciers and oceans were masked out using information from the Digital Chart of the World (ESRI 1993). The image is composed of 1 x 1-km pixels. The color of each pixel was determined by its reflectance at the...

Circumpolar Arctic Vegetation Map (CAVM Team 2003)

Aga circumpolar cavm 2003 side1 Alaska Geobotany Center (AGC) - The Circumpolar Arctic Vegetation Map (CAVM) is a geoecological map of the entire Arctic with a unified legend. It is the first vegetation map of an entire global biome at a comparable resolution. It was funded by the US National Science Foundation (OPP-9908-829), the US Fish & Wildlife Service, the US Geological Survey and the US Bureau of Land Management. The CAVM region is north of the...
