There are four main sections to the Sea Level Tracker:
Data used in calculations for Sea Level Change are pulled from the NOAA Center for Operational Oceanographic Products and Services Application Programming Interface (CO-OPS API). The CO-OPS Data API is a flexible retrieval mechanism for direct access to CO-OPS' products, such as water levels, predictions, currents, meteorological observations, and more. Users can retrieve output in multiple common formats. The CO-OPS Metadata API can be used to retrieve information about CO-OPS' stations. A request can be made to return information about a specific station, or information about multiple stations can be returned. The types of information accessible via the API are listed in detail under Resource Types. Information on how to use to query data through the CO-OPS API can be found here.
To learn more about the tool, we strongly recommend reading the user guide.
