String acknowledgment "The West Coast Ocean Observing System (OOS) Regional Associations collect and disseminate real-time information on oceanographic parameters, including ocean surface currents velocity based on a system of high-frequency-radar (HFR) nodes. Regional partners aid in node maintenance and data collection, but all data is processed through the Coastal Observing Research and Development Center (CORDC) at Scripps Institution of Oceanography.";
String cdm_data_type "Grid";
String comment "Surveys of west coast marine managers, researchers and general users, from both the marine debris and OA communities, have expressed interest in a) general information on coastal oceanographic information across seasons, and b) specific information on how surface currents move along the West Coast at any given time, to track various components of the water (e.g. floating debris). CORDC HFR data provides near-real-time information on actual surface currents data off the West Coast. Compared to satellite-based data collection (e.g. SST, SSH), the CORDC HFR system provides the advantage of being able to collect data even on cloudy days. The CORDC HFR system provides a robust, long-term dataset that can be used for: 1) Studying surface water movements off the West Coast, 2) Identifying persistent eddies and frontal features at various locations, 3) Applications to fisheries tracking/management, and 4) Applications to point-source movements (e.g. debris, contaminants). This is a research project and may contain errors. Please contact with the providers of these products to ensure accuracy before making any critical judgements. Please provide proper source citation when using these products.";

Data Access Protocol (DAP) and its
projection 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.
griddap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/griddap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/griddap/jplMURSST41.htmlTable?analysed_sst[(2002-06-01T09:00:00Z)][(-89.99):1000:(89.99)][(-179.99):1000:(180.0)]
Thus, the query is often a data variable name (e.g., analysed_sst),
followed by [(start):stride:(stop)]
(or a shorter variation of that) for each of the variable's dimensions
(for example, [time][latitude][longitude]).
For details, see the griddap Documentation.
