Alexandria Johnson

Dr. Johnson’s work has tackled a wide range of topics and scientific methods including airborne measurements of water vapor in pre-depression areas over the Atlantic, laboratory studies of water ice nucleation in the atmospheres of Earth and Mars, and high-resolution single cloud models for comparison with maritime cumulus observations. Her current research interests span clouds in atmospheres on Earth, Mars and Exoplanets, the formation, presence, and properties of clouds in the early Lunar atmosphere, and Titan Methane-Ethane-Nitrogen cloud microphysics. Most recently she has developed a novel single particle light scattering instrument to directly measure how atmospheric particulates (clouds and aerosols) interact with radiation across diverse planetary atmospheres.
