"HRDPS, SalishSeaCast, Atmospheric Forcing Fields, Hourly, v23-02

2d hourly atmospheric field values from the Environment and Climate Change Canada HRDPS
continental rotated lat-lon grid atmospheric forcing model that were used to force the
SalishSeaCast NEMO model from 2023-02-23 onward.
The model grid includes the Juan de Fuca Strait, the Strait of Georgia, Puget Sound,
and Johnstone Strait on the coasts of Washington State and British Columbia.
Geo-location data for the atmospheric forcing grid are available in the ubcSSaAtmosphereGridV23-02 dataset.
Atmospheric field values are interpolated on to the SalishSeaCast NEMO model grid on-the-fly by NEMO.

v23-02: atmospheric pressure, precipitation rate, 2m specific humidity, 2m relative humidity,
2m air temperature, short-wave radiation flux, long-wave radiation flux, latent heat net flux,
10m u wind component, 10m v wind component variables";

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.
