Infrared NASA imagery finds Chan-hom organizing, consolidating
On Oct. 6 at 0353 UTC (Oct. 5 at 11:53 p.m. EDT) NASA’s Aqua satellite analyzed Tropical Storm Chan-hom using the Atmospheric Infrared Sounder or AIRS instrument. AIRS found coldest cloud top temperatures as cold as or colder than (purple) minus 63 degrees Fahrenheit (minus 53 degrees Celsius) around the consolidating center.

NASA’s Aqua satellite analyzed the large Tropical Storm Chan-hom as it tracked through the Northwestern Pacific Ocean. Aqua imagery showed the storm was consolidating, indicating a strengthening trend.


One of the ways NASA researches tropical cyclones is using infrared data that provides temperature information. The AIRS instrument aboard NASA’s Aqua satellite captured a look at those temperatures in Chan-hom and gave insight into the size of the storm and its rainfall potential.

Cloud top temperatures provide information to forecasters about where the strongest storms are located within a tropical cyclone. The stronger the storms,
