Abstract: Data were compiled in campaign mode and were obtained over the ice of the Amundsen Gulf. Chemical and meteorological variables were collected with commercial and custom made instrumentation, as detailed below. Ozone (O3): Measurements were taken with TECO TEI049 instrument and five-minute averaged data with filtered generator influence are archived in one file. Wind components and their vertical profile: Wind data were collected by Sodar model Scintec MFAS SN A-C-0073 with software version APRun 1.13. Reported data are at interval of 0.25hour. GPS record is embedded into Sondar data record. In addition, the following data sets have been created by collaborators: (1) Zone vertical profile with home built differential absorption LIDAR (Jim Whiteway, York University, Toronto, ); (2) BrO MAXDOAS (multiaxis differential optical absorption spectroscopy) and LPDOAS (long pass active differential optical absoprtion spectroscopy) (Udo Frieß and Denis Poehler, University of Heidelberg, Germany, , ); (3) BrO by chemical trapping followed by GC/EC analysis (Paul Shepson, Purdue University, USA, ). GPS locations are available in D. Barber et al., Atmosphere-Ocean 48, Issue 4, pp. 225-243, 2010. To obtain atmospheric composition data for furthering understanding of atmospheric processes, particularly with reference to surface ozone and mercury depletion. This study was part of OASIS-Canada program and the CFL (Circumpolar Flaw Lead) campaign. Complementary data are available in the Polar Data Catalogue, CCIN Reference Number 1843.
