Aaron Match

Aaron Match is a Ph.D. student in Atmospheric and Oceanic Sciences. Aaron studies the global circulation of Earth’s atmosphere, with a focus on how interactions among radiation, dynamics, and chemistry lead to variability in the stratosphere. The stratosphere is a stably stratified layer of the atmosphere extending from approximately 15-50 kilometers above the Earth’s surface, containing Earth’s ozone layer. The stratosphere has undergone significant changes over the past few decades, including decreases in ozone concentrations, temperature, and water vapor. These changes can be thought of as the response to forcings by major volcanic eruptions, ozone depletion, greenhouse gas changes, and natural variability, yet there remains uncertainty in the forcings as well as the observed changes themselves. Aaron seeks to apply understanding of the stratospheric response to different forcings from theory and idealized climate model simulations to observational records from satellites and reanalysis datasets in order to advance theoretical understanding of the stratospheric response to forcings, gain insights into the stratospheric dynamics of idealize climate models, and constrain observed stratospheric variability. Advances in the understanding of how particular forcings impact the stratosphere may benefit climate model simulations of past and future variability as well as projections of the impacts of proposed stratospheric aerosol geoengineering. Outside of stratospheric dynamics, Aaron likes poring over science communication blogs and taking weekend bike trips to the Pine Barrens.
