The 18th Workshop on Antarctic Meteorology and Climate.

The 18th Workshop on Antarctic Meteorology and Climate was held on 31 May through 2 June 2023. The Antarctic Meteorological Research and Data Center hosted this hybrid workshop at the Pyle Center at the University of Wisconsin-Madison in Madison, WI, USA. Global members of the Antarctic meteorological community gathered to present and discuss topics from scientific research to operational support within Antarctic meteorology and climate. Students and early career professionals chaired various presentations and discussions while all attendees engaged to share results, build collaborative plans, and discuss further developments. The main workshop topics included updates on the current Automatic Weather Station (AWS) networks, challenges, and planning concerning Antarctic forecasting and operational services, Antarctic numerical modeling systems, observational applications and research, and Antarctic community and data sources. Across six sessions, over 25 different presenters elaborated on their work in areas such as field season updates, atmospheric rivers, remote sensing, the Antarctic Mesoscale Prediction System (AMPS), and forecasting challenges due to data scarcity. Workshop discussions resulted in several key outcomes and action items regarding fieldwork impacts, exploration of field techniques, observation coverage, and communication between operations and research scientists. Future workshops will provide opportunities for continued discussion on the evolution of the AWS network and operational needs while providing a venue to promote collaboration and cooperation for Antarctic meteorology and climate activities.
