Observing System program). Mertes helped develop and refine a technique for using satellite remote sensing data to estimate the amount of sediment suspended in surface waters of rivers and wetlands (Mertes et al. 1993; Gomez et al. 1995). Her technique is useful...
Terra Turns Five
” This false-color map represents the Earth’s carbon “metabolism” — the rate at which plants absorbed carbon out of the atmosphere. The map shows the global, annual average of the net productivity of vegetation on land and in the ocean dur...
Fire! NASA Demonstrates New Technology for Monitoring Fires From Space
Animation of all 50 MAS bands, from .547 µm to 14.17 µm. (2.4MB) False color flyover of Brazilian fires using MODIS Airborne Simulator (MAS) data. The bands used simulate what would be seen in visible light. (3.3MB) Flyover from the same flight track, ...

Life in Icy Waters (DAAC Study)
Microwave/Imager (SSM/I), a passive microwave sensor that measures the amount of radiation emitted by the Earth’s surface, known as brightness temperatures. Brightness temperatures are a gauge of emissivity, or the ability of water or ice to emit radiation at microwave fr...
Growing Data (DAAC Study)
data from the Earth Resources Observation Systems (EROS) Data Center in Sioux Falls, South Dakota. Using Landsat and Advanced Very High Resolution Radiometer (AVHRR) data, the Team produced false color maps showing a variety measurements of interest to environmental scientists....
