Arctic Ocean 2016 - Meteorological and Aerosol Data

This dataset contains data collected during the Canadian-Swedish expedition Arctic Ocean 2016. The research cruise took place August through September 2016, using the icebreaker Oden. For ship data from the cruise, as well as graphics and files describing the route, see https://ecds.se/dataset/meteorological-oceanographic-and-ship-data-from-arctic-ocean-expedition-aug-sept-2016 For descriptions of Work Packages and research conducted during the cruise, see the SWEDARCTIC Arctic Ocean 2016 Expedition Report: http://urn.kb.se/resolve?urn=urn:nbn:se:polar:diva-3475 Additional information on the expedition, including links to publications, is available at http://www.polarforskningsportalen.se/en/arctic/expeditions/arctic-ocean-2016 Work Package: Meteorology, Atmospheric Boundary Layer and Surface Fluxes The meteorology work package has three distinct objectives: 1) Profiling of the thermodynamic structure of the polar atmosphere from the surface to approximately 25 km to provide information on synoptic structure. 2) Measurement of turbulent surface exchange (momentum, heat, water vapour), t

This objective is primarily aimed at the development and evaluation of surface flux parameterizations for use in numerical models, both for operational forecasting and climate studies. 3) Measurement of the aerosol particles on which polar clouds and fog form. The Arctic boundary layer is extremely clean compared to that over the open oceans or continental landmasses – aerosol concentrations are often exceptionally low. Our understanding of the sources of aerosol particles on which Arctic cloud and fog droplets form is poor, and models of aerosol typically struggle to reproduce even basic features of the size distribution and seasonal variability. Data include: Measurements: Wind speed and direction, air temperature, humidity, water vapour concentration, surface temperature, overhead cloud base height, cloud fraction statistics, backscatter profiles from aerosol/cloud droplets, solar and infra red radiation, cloud/fog droplet spectrometry, and aerosol size distributions. Images: 10 second timelapse thermal images of the ice off port side, 10 second (port/stb) and 60 second (forward) visible images of the surface to the horizon. Sampling: Fog water droplets, aerosol particles. A detailed description of data, methods, and equipment is available in the file 'AO16 Meteorological and Aerosol Data Info'. less
