    String summary 
"Forecast, Salish Sea, Surface Tracer Fields, Hourly
Rolling daily forecast of 2d sea surface height and mixed layer depth field values averaged over 1 hour intervals
from Salish Sea NEMO model runs with physics and biology. The values are calculated for the surface of the 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 centre of the intervals over which the calculated model results are averaged.
Geo-location and depth data for the Salish Sea 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 00:05:00 UTC 5 days prior to the most recently completed forecast run,
and extends to 11:55:00 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 00:05:00 UTC to 2017-11-12 11:55:00 UTC.

v1: sea surface height and rainfall rate variables
v16-10: NEMO-3.6; ubcSSnBathymetry2V16-07 bathymetry; see infoUrl link for full details.
        Deleted rainfall rate variable.
v17-02: NEMO-3.6; ubcSSnBathymetryV17-02 bathymetry; see infoUrl link for full details.
        Added mixed layer depth variable (dsigma = 0.01 wrt 10m)
v18-06: NEMO-3.6 SalishSeaCast-201806 configuration; ubcSSnBathymetryV17-02 bathymetry; see infoUrl link for full details.
        Removed mixed layer depth variable

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
For example,
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.
