Data spans from 2015-present. This file is for Year: 2025; Month: 08. The data was funded by NOAA under the Global Drifter Program and collected and provided by the Lagrangian Drifter Laboratory at Scripps Institution of Oceanography. No quality control has been applied except to indicate missing data values. Data that was reported not on the hour timestamp (e.g., a few minutes after) have had the timestamp adjusted to hourly.
