The values are calculated for the entire model grid that includes the Juan de Fuca Strait, the Strait of Georgia, Puget Sound, and Johnstone Strait on the coasts of Washington State and British Columbia. The time values are UTC. They are the centres of the intervals over which the calculated model results are averaged; e.g. the field average values for the 00:00 to 01:00 UTC hour on 2021-06-03 have a time value of 2021-06-03 00:30:00Z. The velocity component values are averaged over the upper 5 and 10 metre depths. Geo-location and depth data for the SalishSeaCast NEMO model grid are available in the ubcSSnBathymetry2V17-02 dataset. 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. v17-02: VelEast10, VelEast5, VelNorth10, VelNorth5 variables; NEMO-3.6; ubcSSnBathymetryV17-02 bathymetry; see infoUrl link for full details. v18-06: NEMO-3.6 SalishSeaCast-201806 configuration; ubcSSnBathymetry2V17-02 bathymetry; see infoUrl link for full details. v18-12: NEMO-3.6 SalishSeaCast-201812 configuration; ubcSSnBathymetry2V17-02 bathymetry; see infoUrl link for full details. v19-05: NEMO-3.6 SalishSeaCast-201905 configuration; ubcSSnBathymetryV17-02 bathymetry; see infoUrl link for full details."; String testOutOfDate "now+24hours"; String time_coverage_end "2024-11-04T11:30:00Z"; String time_coverage_start "2024-10-28T00:30:00Z"; String title "Forecast, Salish Sea, Near-surface Depth Averaged Currents, 1h"; } }
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]).
