AMSR-E Anomalous Atlantic Sea Surface Temperature Data Used to Forecast 2003 Hurricane Season 1
Researchers and forecasters often study sea surface temperatures for an indication of hurricane potential. Scientists say above normal Atlantic Ocean temperatures is one reason for the "above normal" hurricane forecast. Hurricanes convert heat from the tropical atmosphere and oceans to wind and waves, just as a car engine converts gasoline into motion. These animations show a year in the life of global ocean temperatures, June 2, 2002 to May 11, 2003. Green indicates the coolest water, yellow th

Biomass Burning over South America
Biomass burning is the burning of living and dead vegetation. It includes the human-initiated burning of vegetation for land clearing and land-use change as well as natural, lightning-induced fires. Scientists estimate that humans are responsible for about 90% of biomass burning with only a small percentage of natural fires contributing to the total amount of vegetation burned. Burning vegetation releases large amounts of particulates (solid carbon combustion particles) and gases, including gree
