 Data Drifter Data


Drifting buoys provide a platform that allows for the measurement of surface drifts, air pressure and other variables. These measurements allow for validation of models and surface truth for some kinds of satellite data, and contribute to initial fields in climate prediction models. The Surface Velocity Program Data Assembly Centre (DAC) was composed of the Atlantic Atmospheric and Oceanographic Laboratory (U.S.) and the Marine Environmental Data Service (Canada). Together they assembled and provided data of uniform quality from WOCE surface drifters and drifters released under other programmes that met WOCE quality specifications. Data interpolated to every 6 hours are available as well as products such as track plots, mean velocity and temperature fields. There are separate folders for each ocean and each year. Within the folders the data is ordered by platform number and time.
