Research Interests

Gina Jozef is a Ph.D. Candidate in the Department of Atmospheric and Oceanic Sciences. She studies the polar atmospheric boundary layer with John Cassano. Jozef is from Phoenix, Arizona, and studied Environmental Science with a concentration in Physics at Colorado College for her Bachelor’s degree. During graduate school, Gina participated in the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition, collecting observations of the meteorological conditions in the central Arctic lower atmosphere using uncrewed aircraft systems. Aside from analyzing the MOSAiC data, Jozef enjoys engaging in outreach activities regarding MOSAiC, such as sharing about the experience with K-12 students and organizations interested in supporting women in STEM.

Current Research

Analysis to Evaluate and Improve Model Performance in the Central Arctic: Unique Perspectives from Autonomous Platforms During MOSAiC: The Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) was a year-long (October 2019 to September 2020) international research expedition to study the Arctic climate system. Jozef’s role in MOSAiC was to deploy uncrewed aircraft systems (drones) to take measurements of the atmospheric boundary layer (ABL) to study heat, moisture, and momentum exchange with the sea ice and ocean, and how the ABL varies as clouds, radiative fluxes, and large-scale weather changes. Using these drone data, she has determined the best ABL height identification method for the central Arctic. In conjunction with radiosonde data from MOSAiC, Jozef is working on determining the dominant mechanisms dictating the Arctic ABL through the identification of and comparison between various atmospheric features including the ABL height, low-level jets, and temperature inversions. Through a self-organizing map analysis, she is also categorizing the relevant ABL structures in the central Arctic and how they interact with other atmospheric features such as cloud cover and surface radiation budget.
