attribute NC_GLOBAL summary String Global Drifter Program hourly drifting buoy collection. Quality control interpolated (interpolation via mathematical model fitting) data. Hourly Drifter data product exists from early 2000's to present, well suited for observing smaller-scale oceanic processes. NOAA-Atlantic Oceanographic & Meteorological Laboratory (AOML) data from a local source. The hourly QC dataset is updated on a quarterly basis, i.e. every 3 months, in delayed mode, but the data processing team has experienced unforeseen setbacks. The GDP is working as quickly as possible to update the dataset. Please reference the acknowledgment attribute to cite the dataset's DOI.
