"The National Data Buoy Center (NDBC) distributes meteorological data from
moored buoys maintained by NDBC and others. Moored buoys are the weather
sentinels of the sea. They are deployed in the coastal and offshore waters
from the western Atlantic to the Pacific Ocean around Hawaii, and from the
Bering Sea to the South Pacific. NDBC's moored buoys measure and transmit
barometric pressure; wind direction, speed, and gust; air and sea
temperature; and wave energy spectra from which significant wave height,
dominant wave period, and average wave period are derived. Even the
direction of wave propagation is measured on many moored buoys.

The data is from NOAA NDBC. It has been reformatted by NOAA Coastwatch,
West Coast Node. This dataset only has the data that is closest to a
given hour. The time values in the dataset are rounded to the nearest hour.

This dataset has both historical data (quality controlled, before
2018-08-01T00:00:00Z) and near real time data (less quality controlled, from
2018-08-01T00:00:00Z on).";

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://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.
