Summary of activities from 2020-22
- Our activities have been severely impacted by the COVID-19 pandemic. Restrictions on travel has meant that our regular workshops have not taken place. Additionally, restrictions on who can travel South over the past seasons has meant that, for some of our instruments, they have either not been deployed on time or had maintenance delayed.
- Airglow imager gravity wave analysis software now publicly available (M-Transform, program language Interactive Data Language (IDL))
- Instrument deployments/upgrades in 2022: At Comandante Ferraz (CF) station and Halley station there are new all-sky airglow imagers deployed. Upgraded meteor radar at CF station. Wind profiling (MST) radar at Davis upgraded.
- Instrumentation: A new airglow instrument at King Sejong Station, Antarctica for the observations of the mesospheric temperature and gravity waves. Rayleigh LIDAR at South Pole. Upgrade of Meteor radar at Davis
- SCAR OSC session: Polar atmospheric processes: water cycle, snow, clouds, aerosols, radiation and gravity waves
- ANGWIN workshop, hosted by KOPRI, October 2022
- 2023 IUGG assembly joint symposium on Polar regions instrumentation
