Automated Voluntary Observing Ship (AVOS) program meteorological data recorded aboard the M/V NAMAO. January 1st, 2010 to present. Hourly, processed data includes coordinates, temperature (air, water), wind (speed, direction), and pressure (barometric, sea level); provided by Environment and Climate Change Canada.

The second processed dataset provides 10-minute measurements, which includes coordinates, temperature (air and water), wind (speed and direction), pressure (barometric and sea level), ship speed (knots) and orientation. This dataset is curated by CanWIN data curator and is available in CSV format.

For users that require a subset of the 10-minute interval dataset, please use our ERDDAP server for filtering data fields.
