Ionospheric Modeling at URSI AP-RASC 2025

Dima Paznukhov and Keith Groves, ionospheric scientists at BC’s ISR, presented their latest ionospheric modelling results from innovative data assimilation techniques at the 2025 URSI Asia-Pacific Radio Science Conference in Sidney, Australia. Groves’ talk, co-authored by ISR’s Alan Hoskinson & D. Paznukhov, described efforts to improve forecasts of the electron density of the background ionosphere. Paznukhov discussed modern analysis tools that several researchers at ISR and AFRL are developing to accurately specify ionospheric conditions more quickly. Paznukhov also chaired a session on the propagation of high-frequency radio waves through the ionosphere. Groves is currently the Chair of URSI’s Commission on Ionospheric Radio and Propagation (Commission G) and led the Commission G business meeting. He is also on the organizing committee for the triennial URSI General Assembly and Scientific Symposium 2026 which will take place in Poland next year.
