NASA Aircraft Sensors Fly Atmospheric Rivers Study
NASA’s Global Hawk is flying a high-altitude study over the Pacific Ocean in search of atmospheric regions that transport large amounts of water vapor long distances and cause extreme precipitation events. The mission is organized by the National Oceanic and Atmospheric Administration. The aircraft is carrying JPL’s High-Altitude Monolithic Microwave Integrated Circuit Sounding Radiometer, or HAMSR, an advanced microwave atmospheric sounder, and a NOAA automated dropsonde system.

Cut 1 –TRT - (00:20) - “So we are flying the HAMSR instrument on a Global Hawk because A. HAMSR is the most capable, accurate instrument of its kind and the Global Hawk is the platform that allows us to make these measurements for a very long period of time that’s not been possible before.”

Cut 1 –TRT -  (00:19) -The HAMSR instrument produces images. They are actually three-dimensional images of the temperature and water vapor distribution in the atmosphere. This is important for meteorological researchers that are trying to understand the significant phenomena such as hurricanes, atmospheric rivers and winter storms.”
