ERDDAP is a data server that gives you a simple, consistent way to download data in the format and the spatial and temporal coverage that you want.
ERDDAP is a web application with an interface for people to use. It is also a RESTful web service that allows data access directly from any computer program (e.g. Matlab, R, or webpages).
Use ERRDAP to generate .png and .pdf files on-the-fly from gridded and tabular scientific datasets and insert them directly into webpages.
ERDDAP’s search capabilities allow full text searches of the metadata or searches by metadata categories, such as keywords, standard name, and data type.
The Environmental Research Division maintains an ERDDAP server with an extensive collection of environmental datasets. CoastWatch data are drawn from the ERD ERDDAP.
The links below lead to the gridded and tabular data collections, and to a dataset search page.• Gridded Datasets
• Tabular Datasets
• ERDDAP Home
• Search
Your query is sent to ERDDAP in a specially formed URL containing dataset of interest, a description of how you want the data subsetted or graphed, and the file type you want returned to you.
You may use ERDDAPs “Data Access” and “Make A Graph” tools to quickly make the URL or bypass the forms by generating the URL by hand or with a computer program or script.

The following example will generate the image below of the GHRSST Global Daily 1-km Sea Surface Temperature data for the US West Coast for December 23, 2014.
The BaseURL for the Environmental Research Division's ERDDAP server.
https://coastwatch.pfeg.noaa.gov/
For GHRSST Global Daily 1-km SST the ID is “jplG1SST”
https://coastwatch.pfeg.noaa.gov/
For GHRSST Global Daily 1-km SST the ID is “jplG1SST”

Begin the query with “?”, then add the parameter of interest. “SST” in our example.

Each within specification is within square brackets. For our example we need the date and the geographical bounding box.
Date Specification: Date has the format [(YYYY_MM-DDThh:mm:ss], which is [(2014-02-23T00:00:00Z)] for our example.
https://coastwatch.pfeg.noaa.gov/
Bounding Box Specification: The bounding box has the format [(lat min):(lat max)][(lon min):(lon max)] , which is [(32.0):(52.0)][(-135):(-115.0)] for our example.
