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... -
Circumpolar Arctic AVHRR NDVI 1993-1995 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 NDVI Trend 1982-2010 (Bhatt et al. 2010)
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... -
Patterned-Ground 10 x 10 m Grids (Raynolds et al. 2005)
This mapping includes six locations along the Dalton Highway and in the Prudhoe Bay Oilfield area, forming a north-south transect across the climate gradient on the North Slope... -
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,... -
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...
