MODIS Keeps a Watchful Eye on the Storm Impacting U.S. and Canada
Last Updated: 03/04/2011*
Raytheon's Moderate Resolution Imaging Spectroradiometer (MODIS), the keystone instrument on the Earth Observing System Terra and Aqua satellites, has proved to be a major asset to the scientific community for the observation of global climate events.
MODIS is used to observe and monitor fires, volcanic eruptions, dust storms, hurricanes and floods. Most recently, MODIS was tasked to help the National Oceanic and Atmospheric Administration track the impact of the massive winter storm moving across the United States and Canada.
MODIS provides true-color, photo-like imagery within hours of being collected, making the system a valuable resource for monitoring. The MODIS Rapid Response System team provides daily satellite images of weather, ice and land changes to federal agencies such as the U.S. Forest Service, the Department of Agriculture and the Environmental Protection Agency.

Three images from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Terra satellite were combined to create this image of the storm system. The images were captured Jan. 31 at 10:30 a.m., 12:05 p.m., and 1:45 p.m. ET (15:30, 17:05, and 18:45 UTC). Diagonal lines across the image show the boundaries between the overpasses. White gaps are areas where the sensor did not collect data. The image has a resolution of one kilometer (0.62 miles) per pixel. Credit: NASA Goddard MODIS Rapid Response Team |
