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.";

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
For details, see the tabledap Documentation.
