"Surface ocean velocities estimated from HF-Radar are representative

near-real time processing is to produce the best product from 
available data at the time of processing.  Radial velocity 
measurements are obtained from individual radar sites through the 
U.S. HF-Radar Network. Hourly radial data are processed by unweighted 
least squares on a 1km resolution grid of the U.S. West Coast to 
produce near real-time surface current maps.";

使用 griddap 从网格数据集请求数据和图表

griddap允许您通过特殊格式的 URL 从网格数据集中请求数据子集、图表或地图(例如,来自卫星的海面温度数据)。griddap 使用OPeNDAP  (external link)数据访问协议 (DAP )  (external link)及其投影约束 (external link)

URL 指定您想要的内容:数据集、图表或数据子集的描述以及响应的文件类型。

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.
