"This dataset contains ocean surface Eastward wind from SeaWinds on QuikSCAT binned and averaged monthly on 1 degree grids. The coverage is from August 1999 through October 2009. The QuikSCAT Project produced this dataset in support of the CMIP5 (Coupled Model Intercomparison Project Phase 5) under the World Climate Research Program (WCRP) and was first made available via the Earth System Grid. This dataset was derived directly from the QuikSCAT Level 2B dataset, which can be accessed here: https://podaac.jpl.nasa.gov/dataset/QSCAT_LEVEL_2B. The SeaWinds instrument is a conical scanning pencil-beam radar, with dual-beam and dual-polarization capability, operating at Ku-band to provide all-weather ocean surface wind vector retrievals. For more information on the QuikSCAT platform and mission, please visit
https://podaac.jpl.nasa.gov/OceanWind/QuikSCAT .
For more information about this dataset, please see the documents in

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.
