Global Drifter Program

Global Drifter Program ERDDAP Server

The AOML GDP launched their ERDDAP™ server on May 19, 2023, in an effort to increase access to drifter data for the scientific community. ERDDAP™, or Environmental Research Division Data Access Program™, is a scientific data server using free and open-source software created by the Environmental Research Division of NOAA’s Southwest Fisheries Science Center. Currently, the AOML

Hourly Interpolated Drifter Data

This dataset includes hourly sea surface temperature and current estimates using data collected by satellite-tracked surface drifting buoys (“drifters”) of the NOAA Global Drifter Program. The Drifter Data Assembly Center (DAC) at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) has applied quality control procedures and processing to edit these observational data and obtain estimates at

Six-Hourly Interpolated Drifter Data

AOML receives position data computed from Doppler measurements from Argos-tracked drifters or from GPS installed in all Iridium and some Argos drifters. Historically, these data are irregularly distributed in time and they also contain erroneous positions and/or bad Sea Surface Temperature values, therefore not suited for many kinds of analysis or displays. The Drifter Data
