The availability of these data does not constitute publication of the data. These data have not been post-calibrated or quality controlled and are therefore not of the climate quality (less than 2uatm pCO2) that PMEL is required to achieve.  These unverified data are made available to our partners for qualitative use (e.g., generating plots for public outreach and pre-publication analyses). We rely on the ethics and integrity of the user to assure that PMEL receives fair credit for our work.  Only post-calibrated and quality controlled data available at http://cdiac.ornl.gov/oceans/Moorings/ should be used for scientific publications. NaN = missing data or data that have been preliminarily flagged as bad.  Since there is a  less than 1 day delay in flagging bad data, we ask that if the user is generating public plots, that they update the entire time series daily, not just the last day of measurements. From time to time, we may make changes to our database that could affect the data file name, and columns and column names of the data in these files. We will strive to inform you in advance of such changes. If you have any questions, please contact adrienne.sutton@noaa.gov. If you have technical issues related to file contents, please contact john.osborne@noaa.gov.";

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://upwell.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://upwell.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.
