NASA is featuring satellite imagery and data in a video retrospective of Hurricane Katrina the agency has released in time for the five-year anniversary of the most costly storm in U.S. history.
The video, produced by the space agency's Goddard Space Flight Center, showcases data and images generated by NASA satellites during the storm, which devastated the Gulf Coast Region of the U.S. and the effects of which are still being felt.
The opening of the video highlights Atlantic Ocean sea-surface temperatures taken from a NASA satellite called the Advanced Microwave Scanning Radiometer -- Earth Observing System (AMSR-E). The data shows how the warm ocean waters helped the storm build.
The video also features images of how clouds grew as the storm progressed, taken by NASA's Multi-angle Imaging SpectroRadiometer (MISR) instrument on its Terra satellite; as well as data from NASA's Tropical Rainfall Measuring Mission (TRMM) satellite that show how what are called "hot towers" -- or thunderstorms hidden within the hurricane -- intensified it.
The TRMM also captured data on how much rain fell during the hurricane, information also featured in the video.
More familiar images from the video are Landsat satellite images of New Orleans before and during the flooding, which even more than the storm itself wreaked havoc on the city and its residents. More recent Landsat images show a city that is still rebuilding, even five years after the storm.
The Agile ArchiveWhen it comes to managing data, donít look at backup and archiving systems as burdens and cost centers. A well-designed archive can enhance data protection and restores, ease search and e-discovery efforts, and save money by intelligently moving data from expensive primary storage systems.
