In-situ airborne observations collected during flight 304 on 16 March 2018 by the Meteorological Airborne Science Instrumentation (MASIN) on board the British Antarctic Survey (BAS) Twin-otter aircraft for the Iceland Greenland seas Project (IGP) including the Atmospheric Forcing of the Iceland Sea (AFIS) project. This dataset is a quality-controlled revision of the core meteorological data, generated at the University of East Anglia (UEA).
Data were collected over the Iceland and Greenland Sea area.
