Satellites Track Isaac as it Approaches Gulf Coast

National Hurricane Center Website

Tropical Storm, Hurricane Isaac Satellite Tracking } 2012 Atlantic Hurricane Season News & Updates | LiveScience: "While Gulf Coast residents have been warily watching the progress of Tropical Storm Isaac, NASA satellites have been tracking the storm's path and development from above. The latest satellite data show that Isaac is consolidating, a mark of a strengthening storm.

The Atmospheric Infrared Sounder (AIRS) instrument onboard NASA's Aqua satellite acts like an "infrared eye" for storm watchers providing temperature data on Isaac's clouds and the ocean waters around the storm. Cloud temperatures can indicate whether a storm is strengthening or weakening, and knowing the temperature of the surrounding oceans helps forecasters know whether the storm is moving into an environment that will fuel it farther."
