Abstract

ACCACIA was part of the NERC Arctic research programme. (NERC Reference: NE/I028858/1). ACCACIA aimed to improve our understanding of aerosol-cloud interactions in the Arctic, and the potential changes and feedbacks that may result from decreasing Arctic sea ice cover in the future. In situ measurements have been made during two field campaigns utilising ship-based measurements of surface aerosol sources and airborne measurements of aerosol and cloud microphysical properties, boundary layer dynamics, and radiative forcing. The observations have been complemented by modelling studies on a range of scales: from explicit aerosol and cloud microphysics process modelling, through large eddy simulation and mesoscale models, up to global climate models.

This dataset contains meteorological data measured by the Meteorological Airborne Science INstrumentation (MASIN) onboard the British Antarctic Survey Twin Otter aircraft in the North Sea and Svalbard, Norway during the Aerosol Cloud Coupling and Climate Interactions in the Arctic (ACCACIA) project (2013).
