Satellite Imagery of Hurricane Dennis (WMS) |
| Abstract |
Hurricane Dennis started as a tropical depression on August 23, 1999, became a tropical storm on August 24, and was classified as a hurricane early on August 26, near the Bahamas. From August 26 through August 31, Dennis proceeded up the coast of the United States until it stalled off the coast of North Carolina for four days because the pressure trough that was pushing it out to sea left it behind. This animation shows images of Dennis during its hurricane period from August 26 through August 31, 1999, when the stall began. The images were taken by the GOES-8 satellite, a weather satellite in geostationary orbit above the western hemisphere. The continuous white cloud progression came from infrared images from GOES, and the yellowish clouds that come and go with the daylight came from data taken in the visible spectrum, also from GOES. The GOES images were not taken at regular times, so the hurricane appears to slow down when the time between images gets small and speed up when the time between images gets large. |

Global Infrared Cloud Cover, September 2001 (WMS) |
| Abstract |
This animation is a mosaic of cloud cover data taken by several different satellites in the infrared band. One of the most prominent cloud features during this time was Hurricane Erin near the Atlantic coast of the United States. |

GOES-12 Imagery of Hurricane Katrina: Visible Close-up (WMS) |
| Abstract |
The GOES-12 satellite sits at 75 degrees west longitude at an altitude of 36,000 kilometers over the equator, in geosynchronous orbit. At this position its Imager instrument takes pictures of cloud patterns in several wavelengths for all of North and South America, a primary measurement used in weather forecasting. The Imager takes a pattern of pictures of parts of the Earth in several wavelengths all day, measurements that are vital in weather forecasting. This animation shows a daily sequence of GOES-12 images in the visible wavelengths, from 0.52 to 0.72 microns, during the period that Hurricane Katrina passed through the Gulf of Mexico. At one kilometer resolution, the visible band measurement is the highest resolution data from the Imager, which accounts for the very high level of detail in these images. For this animation, the cloud data was extracted from GOES image and laid over a background color image of the southeast United States. |

GOES-12 Imagery of Hurricane Katrina: Longwave Infrared Close-up (WMS) |
| Abstract |
The GOES-12 satellite sits at 75 degrees west longitude at an altitude of 36,000 kilometers over the equator, in geosynchronous orbit. At this position its Imager instrument takes pictures of cloud patterns in several wavelengths for all of North and South America, a primary measurement used in weather forecasting. The Imager takes a pattern of pictures of parts of the Earth in several wavelengths all day, measurements that are vital in weather forecasting. This animation shows a four-day sequence of GOES-12 images in the longwave infrared wavelengths, from 10.2 to 11.2 microns, during the period that Hurricane Katrina passed through the Gulf of Mexico. This wavelength band is the most common one for observing cloud motions and severe storms throughout the day and night. Since GOES-12 takes images most often over the United States (every 5 to 10 minutes), the motion of the clouds in this close-up of the southeast US is very smooth. |

Infrared Cloud Cover over the Atlantic Ocean, September 2001 (WMS) |
| Abstract |
This animation is a mosaic of cloud cover data taken by several different satellites in the infrared band. Instead of showing a global composite, it is cropped to highlight the Atlantic Ocean. One of the most prominent cloud features during this time was Hurricane Erin. |
