OASIS-CANADA-OOTI TARA: Measurements of ozone during the TARA drift over the Arctic Ocean

A full year of measurements of surface ozone over the Arctic Ocean, far removed from land, is presented (72 to 89 degrees North latitude). The data were obtained during the drift of the French schooner TARA between September 2006 and November 2007, while frozen in the Arctic Ocean. Ozone data were collected with a TEI-049 ozone monitor in a fully automated manner during the TARA drift at 10 seconds intervals. Five-minute averages of quality-controlled ambient data are archived in the Polar Data Catalogue. Data that have possibly been influenced by the ship's generator and instrument instability are filtered out. Date and time stamp (UTC) are included with averaged ozone values archived in one file. GPS location during the drift was recorded by the Damocles project and is reported at the following location: http://www.damocles-eu.org/research/TARA_ARCTIC_2007-2008_The_Great_Arctic_drift_54.shtml. A file with GPS coordinated from ship's log is provided in one data file.
