I am a DPhil student in the Climate Processes group supervised by Dr Philip Stier.
My research focuses on aerosol-cloud interactions in mixed-phase clouds in the Arctic. The clouds in Earth’s atmosphere exist because water vapour has condensed around floating aerosols – tiny specks of dust, soot, sulfates, pollen, sea salt, bacteria, plant matter, and other particles – to form cloud droplets. In mixed-phase clouds, some droplets have frozen into the ice phase, while some persist in a supercooled liquid phase despite below-freezing ambient temperatures. Ice and water have very different radiative properties, so the phase ratio within a mixed-phase cloud determines how much shortwave radiation (light) the cloud reflects and how much longwave radiation (heat) it traps. Understanding how the aerosol components of cloud droplets determine their phase is essential to future projections of climate change.
