"The NOAA NDBC SOS server is part of the IOOS DIF SOS Project.  The stations in this dataset have currents data.

Because of the nature of SOS requests, requests for data MUST include constraints for the longitude, latitude, time, and/or station_id variables.

WARNING: Always check the quality_flags before using this data. A simple criterion is: only use a row of data if the first quality_flags value for the row (overall bin status) is 3 (good data/passed quality test). You can do this by appending &quality_flags=~\"3;.*\" to your request.";

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

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://upwell.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://upwell.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.
