Part of NASA's Earth System Science Pathfinder (ESSP) Mission International Partnership between NASA & CONAE, Aquarius provides unprecedented global maps of surface sea water salinity (SSS) to discover how our oceans respond to climate change and the water cycle. Sea surface salinity, along with sea surface temperature, determines the sea surface density. This controls the formation of water masses in the ocean and regulates the 3-dimensional ocean circulation. Aquarius documentation is at";

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{?query}
For example,[(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.
