Airborne in-situ observations of core meteorological data collected by the MASIN instruments on board the British Antarctic Survey instrumented Twin Otter aircraft for the Orchestra project. The core data was collected from Rothera Station Antarctica between 2nd and 16th December 2017 and from the Falkland Islands between 7th and 23rd February 2019. 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.

ORCHESTRA is a NERC-funded Long Term Science programme that involves scientists from many NERC Centres. This 5 year project began in spring 2016 and will use a combination of data collection, analyses and computer simulations to radically improve our ability to understand and predict the circulation of the Southern Ocean and its role in the global climate, with particular emphasis on the way that the Southern Ocean absorbs and stores heat and carbon.
