The Hurricane and Severe Storm Sentinel (HS3) is a five-year mission specifically targeted to investigate the processes that underlie hurricane formation and intensity change in the Atlantic Ocean basin. The NASA Global Hawk UASs are ideal platforms for investigations of hurricanes, capable of flight altitudes greater than 55,000 ft and flight durations of up to 30 h. HS3 will utilize two Global Hawks, one with an instrument suite geared toward measurement of the environment and the other with instruments suited to inner-core structure and processes.

Additional interview clips from Scott Braun including information on why we need to study hurricanes in general, and also the highly collaborative nature of the HS3 campaign, which involves several NASA centers, NOAA, and several universities.
This animation shows how NASA scientists investigated the Saharan Air Layer during Hurricane Nadine. The blue to white data in the curtains is attenuated backscatter from CPL. The dropsonde data is showing relative humidity where blue represents dry air and red represents moist air.
