The Clouds, Hazards, and Aerosols Survey for Earth Researchers (CHASER) satellite mission concept responds to the IPCC and Decadal Survey concerns by studying the activation of CCN and their interactions with clouds and storms. The CHASER satellite mission was developed to remotely sense quantities necessary for determining the interactions of aerosols with clouds and storms. CHASER will make the first global survey of Na, the activated CCN spectrum, and the vertical profiles of cloud properties directly affecting climate. CHASER will complement and transcend current National Aeronautics and Space Administration (NASA) Earth Science Missions studying aerosols, clouds, and thunderstorms. CHASER will determine vertical profiles of cloud parameters and lightning flashes pointing 30° off track toward sun-illuminated cloud surfaces, which minimizes shadowing. CHASER will use a high-heritage Cloud Profiler Suite (CPS) consisting of two instruments pointing 30° off nadir across track toward sun-illuminated surfaces on the east.
