AVHRR Imagery The Ocean Remote Sensing Group receives real-time AVHRR (Advanced Very High Resoluton Radiometer) data from the NOAA polar-orbiting satellites. These broadcast data are received via a 5-m dish operated by the JHU/APL Space Department's Satellite Communications Facility. These data are then processed automatically in real-time and posted as various products on the web. Sea Surface Temperature. Real-time sea surface temperature imagery off the east coast of North America and the Gulf of Mexico. Overviews. Real-time graphical representations of area coverage and gray-scale versions of recently acquired AVHRR imagery. Dynatrack. Real-time color-composite imagery over various land areas of the United States generated from AVHRR imagery. Hurricanes. Hurricane imagery generated from AVHRR data. This site is very active during hurricane season. Archive imagery is also available. Image Gallery. Selected AVHRR imagery.
