Uinta Basin Snow Shadow: Impact Of Snow-Depth Variation On Winter Ozone Formation, Michael J. Davies, John R. Lawson, Trevor O’Neil, Seth N. Lyman, Karlee Zager, Tristan D. Coxson Aug 2025

Uinta Basin Snow Shadow: Impact Of Snow-Depth Variation On Winter Ozone Formation, Michael J. Davies, John R. Lawson, Trevor O’Neil, Seth N. Lyman, Karlee Zager, Tristan D. Coxson

Bingham Research Center

After heavy snowfall in the Uinta Basin, Utah, elevated surface ozone occurs if a cold-air pool persists and traps emissions from oil and gas industry operations. Sunlight and actinic flux from a high-albedo snowpack drive ozone buildup via photolysis. Snow coverage is paramount in initiating the cold pool and driving ozone generation. Its depth is critical for predicting ozone concentrations. The Basin’s location leeward of the Wasatch Mountains provides conditions for a precipitation shadow, where sinking air suppresses snowfall. We analyzed multiple years of ground-based snow depth measurements, surface ozone data, and meteorological observations; we found that ozone levels track …

Small Satellite Conference

Recent advances in the size, weight, and power (SWaP) requirements for space-based sensing have dramatically increased the demand for high-bandwidth downlink. However, high data rate RF transceivers still pose significant SWaP and cost restrictions, especially for university-class CubeSat missions. Optical communication may provide a solution to this challenge, enabling data transmission with order-of-magnitude rate increases over RF while being both secure and SWaP-efficient. The Polarization-modUlated Laser Satellite Experiment (PULSE-A) is a University of Chicago mission to demonstrate optical downlink at a data rate of up to 10 Mbps using circular polarization shift keying (CPolSK). PULSE-A comprises a <1.5U Optical Transmission Terminal, 3U CubeSat Bus, Optical Ground Station (OGS) employing an amateur telescope, and RF Ground Station (RFGS), all of which are being designed and integrated by a team of over 60 undergraduate students. The mission objective is threefold: (1) to provide hands-on educational experiences for undergraduate students, (2) to make hardware for optical communication systems more accessible via open-source design, and (3) to explore the viability and potential advantages of using CPolSK for optical downlink.
