1. 1 Global Hawk Pacific (GloPac)

2. Science Objectives and Missions First demonstration of the Global Hawk unmanned aircraft system (UAS) for NASA and NOAA Earth science research and applications. Validation of instruments on-board the Aura satellite. Exploration of trace gases, aerosols, and dynamics of remote upper Troposphere / lower Stratosphere regions. Sample polar vortex fragments and atmospheric rivers. Risk reduction for future missions that will study hurricanes and atmospheric rivers.
