    String summary "This dataset of remote sensing reflectance measurements was collected as part of a Cullen Fellowship PhD between the National University of Ireland, Galway and the Marine Institute. The data was collected on the RV Celtic Explorer during scientific cruises CE19009 and CE19010 in the North East Atlantic from May to July 2019. The data was collected from TriOS RAMSES-ARC Hyperspectral and TriOS RAMSES-ACC-VIS Hyperspectral UV-VIS Radiometers using the TriOS RAMSES MSDA_XE software. These data are the subset of data from stations during daylight hours from these cruises. Remote sensing reflectance measurements were derived using a five step scripted process in Mathworks (Matlab).";

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
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
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.
