Amazon forest shows unexpected resiliency during drought
User rating: 4.2 / 5 after 16 vote(s)
This image shows how the Amazon forest canopy's 'greenness' differs from normal for the months of July-September 2005 (drought peak). The greenness data is derived from NASA-EOS MODerate Imaging Spectroradiometer (MODIS) sensor aboard Terra Satellite. Green indicates above normal vegetation productivity compared to the 2000-2006 average, red indicates below normal, and yellow corresponds to normal . The study area is highlighted over a true color image background from NASA-EOS MODIS sensor for South America.
