VORTEX > Verification of the Origins of Rotation in Tornadoes Experiment
Two NOAA polar orbiting satellites carried the AVHRR sensor during VORTEX. AVHRR has five spectral channels in the visible, near-infrared and infrared. Data consists of 1 km resolution HRPT or LAC and 4 km resolution GAC imagery over a 1600 km swath. Up to 4 overpasses of the VORTEX region occur daily.
