THINICE: a field campaign dedicated to studying interactions between Arctic cyclones, clouds and sea ice
THINICE is an international airborne field campaign that occurred in Svalbard in August 2022 co-organized by French, British and US colleagues. It was dedicated to studying the dynamics of Arctic cyclones (ACs), moist intrusions, tropopause polar vortices (TPVs), their interactions with cloud microp...

THINICE is an international airborne field campaign that occurred in Svalbard in August 2022 co-organized by French, British and US colleagues. It was dedicated to studying the dynamics of Arctic cyclones (ACs), moist intrusions, tropopause polar vortices (TPVs), their interactions with cloud microphysics, sea surface and sea ice. Two instrumented research aircraft were deployed: the ATR42 aircraft operated by SAFIRE, the French facility for airborne research, and the Twin Otter aircraft operated by the British Antarctic Survey (BAS). The objectives of the ATR42 flights were to observe the structure and evolution of Arctic cyclones over the whole tropospheric column with a focus on mixed phase clouds within Arctic cyclones.
