NASA: Global Hawk Pacific GloPac 2010
During an airborne campaign in spring 2010, NASA’s Global Hawk autonomous plane will carry 11 instruments to sample the chemical composition of air in Earth’s two lowest atmospheric layers — the stratosphere and troposphere — profile the dynamics and meteorology of both, and observe the distribution of clouds and aerosol particles. The instruments are operated by scientists and technicians from seven science institutions and are funded by NASA and the National Oceanic and Atmospheric Administration (NOAA).
