The Clouds of Isidore
These views of Hurricane Isidore were acquired by the Multi-angleImaging SpectroRadiometer (MISR) on September 20, 2002. After bringinglarge-scale flooding to western Cuba, Isidore was upgraded (on September21) from a tropical storm to a category 3 hurricane. Sweeping westwardto Mexico’s Yucatan…
Inside Hurricane Isidore
This image captures the formation of Hurricane Isidore, the first major storm of the 2002 Atlantic hurricane season. Isidore first developed from a tropical disturbance north of Venezuela on September 14. The image shows the vertical structure of precipitation within…
Prospecting from Orbit
With help from the ASTER instrument aboard the NASA’s Terra satellite, scientists at the U.S. Geological Survey have embarked on an ambitious effort to create a worldwide map of well-exposed metal ore deposits.
Tropical Storm Isidore
Tropical Storm Isidore is bringing heavy rains and high winds to the Louisiana Gulf Coast on September 25, 2002. Moving northward at roughly 12 miles per hour, Isidore is packing sustained winds of 65 miles per hour and is expected…
Season’s First Snow in Colorado
Snowfall returned to the mountain ranges of western and central Colorado on September 18—the first significant accumulation of the 2002-03 snow season. Ski resorts in the region report several inches of accumulation. Most of Colorado experienced drought conditions throughout the…
Namib-Naukluft National Park, Namibia
Namib-Naukluft National Park is an ecological preserve in Namibia’s vast Namib Desert.Coastal winds create the tallest sand dunes in the world here, with some dunes reaching980 feet (300 meters) in height. This image was acquired byLandsat 7’s Enhanced Thematic Mapper…
A Star of Japan, Hakodate City
Hakodate City is a seaport located on two bays in the Oshima Peninsula near the south end of the major Japanese island of Hokkaido. This image nicely illustrates how sunglint reflecting off the ocean reveals internal waves impinging on the…
Hurricane Isidore
With maximum sustained winds close to 105 mph (165 km/hr), Hurricane Isidore is wreaking havoc on the island nation of Cuba. The center of the storm is located near 21.7 north longitude and 83.9 west latitude, about 65 miles eat…

Distinguishing Natural Aerosols from Human Pollution
By measuring precisely how much light is reflected at visible and near-infrared wavelengths, the MODIS sensors can also distinguish between aerosol plumes of large particles (more than 1 micrometer) and small particles (less than 1 micrometer).
Locust!
By tracking rainfall-induced changes in vegetation in the desert locust’s habitat, scientists can help predict when conditions are becoming ripe for the formation of a plague.
