This image shows the well-developed eye and eyewall of the hurricane and the ocean surface can be seen through the eye of the hurricane. This visual spectrum image was captured by the National Oceanic and Atmospheric Administration ... Full description.

Aerosols are tiny particles suspended in the air. Some occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray. Human activities, such as the burning of fossil fuels and the alteration of natural surface cover, also generate aerosols. In this animation, data from the National Oceanic and Atmospheric Administration (NOAA) polar-orbiting ... Full description.

During tropical storm and hurricane activity, the National Oceanic and Atmospheric Administration (NOAA) flies aircraft into the storms to acquire highly accurate data on wind speeds, pressure, and other parameters. The planes fly directly into the most intense areas of the storm and the hurricane eye to collect data about the storm. This animation shows the flight paths of two missions of the WP-3D ...

Between 8:20 and 8:30 PM local time on March 12, 2006, the city of Springfield, Illinois was affected by a pair of tornadoes which measured F2 on the Fujita scale. These tornadoes killed 2 people, injured 50, and caused $2.5 million in damage. This animation begins on March 11, 2006 showing cloud movement over the Central plains of the United States then switches to color enhanced infrared imagery ... Full description.

The National Oceanic and Atmoshpheric Administration's (NOAA) polar-obriting satellites monitor the ozone levels around the globe. The ozone layer acts to protect life on Earth by blocking harmful ultraviolet rays from the sun. The "ozone hole" is a severe depletion of the ozone layer high above Antarctica. It is primarily caused by human-produced compounds that release chlorine and bromine gases ... Full description.

This poster (36" x 14") features four satellite images of Hurricane Katrina showing its movement from Florida to Louisiana. With each successive day, the hurricane is more organized with a well-developed eye and eyewall visible on August 28, 2005 before it made landfall on the U.S. Gulf Coast near New Orleans. At peak strength the hurricane was a category 5 storm with winds near 175 miles per hour. ... Full description.

This animation shows all of the cyclonic activity associated with the 2005 hurricane season from June to November. The 2005 season was a record breaker: the most named storms; three of the six most intense storms on record; the latest forming storm; and the most costly season in property damages. The infrared imagery was captured by the National Oceanic and Atmospheric Administration (NOAA) GOES-12 ... Full description.

This animation shows the progression of Hurricane Katrina as it intensifies from a tropical storm on August 22, 2005 to a hurricane. The hurricane crosses the Florida peninsula and reintensifies in the Gulf of Mexico. Hurricane Katrina makes landfall near New Orleans on August 29, 2005 at 7am local time. Notice how rapidly the storm reorganizes once it reaches the warm waters of the Gulf of Mexico. ... Full description.

The 2006 ozone hole over the Antarctic was the largest ever observed. This poster shows images of the ozone hole, one from each month, as observed by the National Ocean and Atmospheric Administration (NOAA) satellites that orbit the poles. The poster dimensions are 24" x 36" and is in high resolution 300dpi format for printing. Full description.

The Group on Earth Observations (GEO) is an international body composed of governments, organizations, and commercial companies. Their satellite systems are one component of the Global Earth Observation System of Systems (GEOSS) that are used to monitor all aspects of the environment. In this animation, all of the satellites involved in GEOSS are shown in their actual orbits, as of August 2006. This ... Full description.
