of Meteorological Satellites (EUMETSAT) METOP satellite. The current 
geophysical model function (GMF) being used is CMOD5.5, where the GMF relates 
the normalized radar cross-section to the ocean surface wind speed and

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 is a superset of the
OPeNDAP DAP hyperslab protocol.

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
   http://cwcgom.aoml.noaa.gov/erddap/griddap/datasetID.fileType{?query}
For example,
   http://cwcgom.aoml.noaa.gov/erddap/griddap/erdBAssta5day.htmlTable?sst[(2007-10-21T00:00:00)][0][(-75):100:(75)][(180):100:(360)]
Thus, the query is often a variable name (e.g., sst),
followed by a set of [] for each of the variable's dimensions
(for example, [time][altitude][latitude][longitude]),
with your desired (start):stride:(stop) values within each [].

For details, see the griddap Documentation.
