"THIS DATASET WILL NOT BE UPDATED AFTER 2011-05-23. This dataset was terminated with the demise of the AMSR-E sensor on Aqua. 
Analyzed Foundation, Microwave + InfraRed Optimally Interpolated, Science Quality, Global, Sea Surface Temperature data. The through-cloud capabilities of microwave radiometers provide a valuable picture of global sea surface temperature (SST). To utilize this, scientists at Remote Sensing Systems have calculated a daily, Optimally Interpolated (OI) SST product at quarter degree (~25 kilometer) resolution. This product is ideal for research activities in which a complete, daily SST map is more desirable than one with missing data due to orbital gaps or environmental conditions precluding SST retrieval. Improved global daily NRT SSTs should be useful for a wide range of scientific and operational activities. The addition of SST derived from Infrared (IR) measurements allows higher spatial resolution, and SST near land.  However, IR input is less accurate than MW due to cloud contamination. Blending MW and IR enables greater coverage and higher accuracy than IR only SSTs, but current OI does not completely eliminate cloud contamination inherent to IR SSTs.";

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.
