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://upwell.pfeg.noaa.gov/erddap/griddap/datasetID.fileType{?query}
For example,
http://upwell.pfeg.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 [].
