NASA’s Global Hawk aircraft was deployed to Florida from Armstrong Flight Research Center at Edwards, CA. on Oct. 6 to monitor and take scientific measurements of Hurricane Matthew.  The unmanned Global Hawk will gather scientific data in support of NOAA’s Sensing Hazards with Operational Unmanned Technology (SHOUT) mission.

An Infrared Look at Hurricane Matthew from NASA's AIRS

A JPL-developed advanced atmospheric sounding system aboard NASA’s Aqua satellite is providing important insights into the inner workings of dangerous Hurricane Matthew.

Image above: NASA’s Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua satellite captured this infrared view of Hurricane Matthew over the Bahamas at 11:27 a.m. PDT (2:27 p.m. EDT) on Oct. 6, 2016. The colors denote cloud top temperatures, with the most intense thunderstorms shown in purple and blue. Image Credits: NASA/JPL-Caltech.

Hurricane Matthew, currently an extremely dangerous Category 4 storm on the Saffir-Simpson Hurricane Wind Scale, continues to bear down on the southeastern United States. At 11:27 a.m. PDT (2:27 p.m. EDT and 18:23 UT) today, NASA’s Atmospheric Infrared Sounder (AIRS) instrument aboard NASA’s Aqua satellite observed the storm as its eye was passing over the Bahamas. The AIRS false-color infrared image shows that the northeast and southwest quadrants of the storm had the coldest cloud tops, denoting the regions of the storm where the strongest precipitation was occurring at the time. Data from the Advanced Microwave Sounding Unit (AMSU), another of AIRS’ suite of instruments, indicate that the northeast quadrant, which appears smaller in the infrared image, likely had the most intense rain bands at the time. The AIRS infrared image shows that at the time of the image the storm had full circulation, with a small eye surrounded by a thick eye wall.
