Using griddap to Request Data and Graphs from Gridded Datasets

griddap lets you request gridded data (for example, environmental data from satellites) and graphs of gridded data, via specially formed URLs.
The URLs specify everything: the dataset, the desired file type for the response, and the subset of data that you want to receive.
You can form these URLs by hand or with a computer program,
or (much easier) you can use the dataset's "Data Access Form" (oriented to requests for data)
or the dataset's "Make A Graph" form (oriented to requests for graphs and maps),
both of which generate the URL when the form is submitted.
griddap is a superset of the OPeNDAP DAP hyperslab protocol.

griddap request URLs must be in the form
   http://edac-dap2.northerngulfinstitute.org/erddap/griddap/ datasetID fileType {?query}
For example,
   http://edac-dap2.northerngulfinstitute.org/erddap/griddap/erdBAssta5day.htmlTable?sst[(2007-10-21T00:00:00)][0][(-75):100:(75)][(180):100:(360)]

For details, see the griddap Documentation.
