Alexander Lozinski is a postdoctoral scholar at the Department of Atmospheric and Oceanic Sciences, University of California Los Angeles, where he researches the physics of Earth’s radiation belts with a focus on event-based prediction and space weather forecasting.

He completed his PhD at the British Antarctic Survey and University of Cambridge in 2021, and during this time developed the BAS-PRO numerical model of Earth’s proton radiation belt. He continues to collaborate with BAS on the Sat-Risk project, which involves implementing a real-time version of BAS-PRO to predict the exposure of orbiting satellites to trapped proton radiation.

Research interests

I am primarily interested in Earth’s proton radiation belt, and the exposure of orbiting satellites to trapped proton radiation. I also have an interest in numerical modelling, and am the developer of BAS-PRO, the British Antarctic Survey proton belt model.

My interests are tied together in the Sat Risk project, where I am working on implementing a real-time forecast of proton belt flux using BAS-PRO. This will be used to calculate the solar cell degradation of satellites in real time.

1. Sat Risk

   The Sat-Risk project, led by the British Antarctic Survey (BAS), has the goal of ‘developing a real-time system to forecast radiation exposure to satellites for a range of different orbits, and quantify the risk of damage or degradation‘.

1. Space weather causes radiation damage to satellites

   The use of electric propulsion for raising satellites into geostationary orbit can result in significant solar cell degradation according to a new study. The extended journey results in greater exposure […]
