Dataset Title:  Sea Surface Temperature (SST) from Great Lakes Surface Environmental
Analysis (ACSPO GLSEA), The ACSPO GLSEA is the developed product that uses the
Advanced Clear-sky Processor for Oceans (ACSPO) L3S-LEO SST as the input data
source. The L3S-LEO SST is the level 3 Super Collated data from Low Earth Orbit
satellites sensor including NPP, N20, and MetOp A/B/C. Geodetic coordinate
system (LAT, LON), 2021-present

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.
