Infrared NASA Look at Cyclone Irina (IMAGE) NASA/Goddard Space Flight Center Caption When NASA's Aqua satellite passed over Irina on March 5 at 2211 UTC (5:11 p.m. EST) it captured an infrared image of the storm's cloud top temperatures using the Atmospheric Infrared Sounder (AIRS) instrument. AIRS data showed that the coldest (purple) cloud top temperatures (colder than -63F/-52.7C) that included the bulk of the showers and strongest thunderstorms were on the southern side of the storm.
