Aqua MODIS Sea Surface Temperature Granules during Hurricane Katrina
The Aqua satellite orbits the Earth every 99 minutes in a polar, sun-synchronous orbit. The MODIS instrument on Aqua observes reflected light from the Earth in 36 spectral frequencies. These observations can be processed to show many properties of the Earth's surface, from temperature and phytoplankton measurements near the surface of the ocean to fire occurrences and land cover characteristics on the land surface.
The MODIS observations start out divided into 5-minute sections called granules, and this animation shows MODIS sea surface temperature data from about 4 days of individual Aqua granules. Sea surface temperature can only be measured by MODIS in ocean regions that are free of both clouds and sun glint, the bright band of specular reflection in the center of each granule.
Four days of Aqua MODIS sea surface temperature granules during the period of Hurricane Katrina, from August 27, 2005 through August 30, 2005.
