NASA Infrared Image of Hurricane Igor Shows 170F Temperature Difference (image) NASA/Goddard Space Flight Center Share Print E-Mail Caption This impressive infrared image of Hurricane Igor from NASA's AIRS instrument shows a clear and large eye, and very strong convection (purple) and high, powerful thunderstorm cloud tops around his center. The image was captured from the AIRS instrument on NASA's Aqua satellite on Sept. 14 at 14:47 UTC (10:47 a.m. EDT). Note the warm ocean temperatures (dark orange) well over the 80 degree F threshold needed to maintain intensity.
