Upper Kuparuk River Region SPOT NDVI
The French SPOT satellite data (20-m resolution) were obtained on 28 July 1989 and provides a view of the mapped region from space. NDVI is an index of vegetation greenness that... -
Upper Kuparuk River Region NDVI trend 1985-2007 (Raynolds et al 2010)
Landsat TM and ETM data were used to calculate NDVI for the study area (823 km^2). This image shows the results of a slope of linear regression of NDVI for 1985, 1989, 1995,... -

Circumpolar Arctic AVHRR NDVI Map
The normalized difference vegetation index (NDVI) is a measure of greenness. NDVI was calculated as: NDVI = (NIR - R) / (NIR + R), where NIR is the spectral reflectance in the... -
Circumpolar Arctic AVHRR False Color-Infrared (CIR) Map
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... -
Sagwon Patterned-Ground 10 x 10 m Grids
The Sagwon patterned-ground grids are located at the northern edge of the rolling foothills, at the boundary with the flatter coastal plain. This is also the boundary between... -

The normalized difference vegetation index (NDVI) is a measure of greenness. NDVI was calculated as: NDVI = (NIR - R) / (NIR + R), where NIR is the spectral reflectance in the... -
Franklin Bluffs Patterned-Ground 10 x 10 m Grids
The Franklin Bluffs patterned-ground grids are located in Subzone D, on the coastal plain of the Alaska North Slope, just west of the Sagavanirktok River. There are three 10 x... -
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... -
