Airborne in-situ observations of core meteorological data collected by the Meteorological Airborne Science INstrumentation (MASIN) instruments on board the British Antarctic Survey instrumented Twin Otter aircraft for the Arctic Summer-time Cyclones: Dynamics and Sea-ice Interaction project. The core data were collected in the Svalbard, Norway and Iceland Sea region between 29th July 2022 and 20th August 2022. The data is from a variety of instruments (temperature, humidity, wind, surface temperature, radiation and position), it is stored in NetCDF format using CF conventions.

This collection also contains surface turbulence, sea-ice fraction and sea-ice melt pond fraction data derived from the core aircraft measurements.

The UK component of the Arctic Summertime-cyclones project field experiment are funded by the Natural Environment Research Council (NERC) NE/T006773/1, NE/T006811/1 and NE/T00682X/1. They will joined by teams from the USA and France, funded by the Office of Naval Research (USA).
