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... -
Ivotuk Vegetation Maps (Reidel et al. 2005)
The Ivotuk study site is located in northwestern Alaska, on the North Slope of the Brooks Mountains Range. The study site was chosen because four tundra vegetation types, moist... -
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 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... -
Circumpolar Arctic AVHRR NDVI Trend 1982-2008 (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...
