NASAs GRIP campaign took place from August - September 2010. During this field experiment, a number of aircraft were mounted with scientific instruments that were tasked with the goal of observing and collecting data about tropical cyclones as they formed in the North Atlantic. HAMSR was one of the instruments that was mounted aboard the Global Hawk aircraft during GRIP.
