"Forecast, Salish Sea, 2d Wave Fields, 30min, v17-02

Rolling daily forecast of 2d wave field values calculated at 30 minute intervals
from the most recent Strait of Georgia WaveWatch III® model forecast runs.
The values are calculated for a model grid that covers the Strait of Georgia
on the coast of British Columbia. The time values are UTC.

The Strait of Georgia WaveWatch III® model grid and configuration were developed
by Johannes Gemmrich at the University of Victoria. The WaveWatch III® model
is forced with currents from the Salish Sea NEMO model and the same ECCC HRDPS
GEM 2.5km resolution winds that are used to force the NEMO model.

This dataset is updated daily to move it forward 1 day in time.
It starts at 00:00:00 UTC 5 days prior to the most recently completed forecast run,
and extends to 11:30:00 UTC on the 2nd day after the forecast run date.
So, for example, after completion of the 10-Nov-2017 forecast run,
this dataset included data from 2017-11-05 00:00:00 UTC to 2017-11-12 11:30:00 UTC.

Using griddap to Request Data and Graphs from Gridded Datasets

griddap lets you request a data subset, graph, or map from a gridded dataset (for example, sea surface temperature data from a satellite), via a specially formed URL. griddap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its projection 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.

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.
