The UHSLC provides an independent quality assessment of the time series and makes FD data available within 4-6 weeks of collection. This is a \"fast\" turnaround time compared to Research Quality (RQ) data, which are available on an annual cycle after a level 2 quality assessment. RQ data replace FD data in the data stream as the former becomes available.

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection 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.

Tabledap request URLs must be in the form
For example,
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
