Tracking Clouds (DAAC Study)
common birthplaces of many storms. Currently, the cloud motion data used to derive wind measurements are observed from geostationary satellites. These instruments orbit the equator, obtaining images of the Earth’s surface below to roughly 55 d...
Observing Volcanoes, Satellite Thinks for Itself
available opportunity, on December 4, 2006. The system transmitted a preview of the data to JPL on December 4, showing the intense thermal emission characteristic of ongoing volcanic activity. Complete high-resolution images and thermal data pi...
A Burning Question (DAAC Study)
examined only spectral information, the differences between instrument channels," Christopher said. The researchers compared data from two sensors, the Advanced Very High Resolution Radiometer (AVHRR) and Earth Radiation Budget Experiment (ERBE) scanner, both...
Terra Turns Five
Five years ago NASA’s Terra satellite began measuring Earth’s vital signs with a combination of accuracy, precision, and resolution the world had never before seen. Today, Terra completes the fifth year in what was scheduled to be at least a 6-...
Fire! NASA Demonstrates New Technology for Monitoring Fires From Space
Goddard DAAC) NASA Demonstrates New Technology for Monitoring Fires from Space —by David Herring May 29, 1998 Earth scientists at NASA's Goddard Space Flight Center recently demonstrated that the MODIS instrument, scheduled to launch in December 1999 on NASA's Earth Observ...
UARS Cornucopia
by Matt Nelson April 24, 2000 Nine years after its initial deployment, the Upper Atmosphere Research Satellite (UARS) is more than just an antiquated piece of metal floating around in space. Actually, it has already surpassed its original mission lifetime of 18 months...
Sensing Remote Volcanoes (DAAC Study)
location. The South Sandwich Islands are situated between the southern tip of South America and mainland Antarctica, one of the most isolated areas of volcanic activity on Earth. More than 1,500 potentially active volcanoes dot the Earth’s lan...
Domes of Destruction (DAAC Study)
where hotter-than-average molten rock from the Earth’s mantle begins to move upward through the Earth’s crust. Where hot spots burn through the crust, volcanoes form. NASA’s newest satellite sensor, the Advanced Spaceborne Thermal Emission and R...
ICESat Factsheet
travel back to GLAS. Halving the total travel time, and applying corrections for the speed of light through the atmosphere, the distance from ICESat to the laser footprint on Earth can be calculated. ICESat will collect data for calculating its...
Bright Lights, Big City
U.S., Europe, and Japan are brightly lit by their cities, while the interiors of Africa, Asia, Australia, and South America remain (for now) dark and lightly populated. (Data courtesy Marc Imhoff of NASA GSFC and Christopher Elvidge of NOAA NGDC. Image by Cr...
