Surface temperature and vegetation index retrieval from 1984 to 2011 in suppo...
In this research a time series of Landsat imagery was processed to retrieve surface reflectance, surface temperature, surface emissivity and a vegetation index (NDVI) from 1984... -
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,... -

Deadhorse Patterned-Ground 10 x 10 m Grids
The Deadhorse patterned-ground grid is located near the industrial center of Deadhorse, AK, within 15 km of the Beaufort Sea coast. There is one 10 x 10 m grid, with a complex... -
Howe Island Patterned-Ground 10 x 10 m Grids
The Howe Island biocomplexity grid is located on a 1.5 x 0.5 km island off the delta of the Sagavanirktok River, west of the Endicott Causeway in the Prudhoe Bay oilfield, AK.... -
Happy Valley Patterned-Ground 10 x 10 m Grids
The Happy Valley patterned-ground grids are located in Subzone E, the warmest part of the Arctic, in the foothills of the Brooks Range, just west of the Sagavanirktok River and... -
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... -
Alaska 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... -
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... -
