For most sites, raw data files of sea surface elevation for the last month are available to download. These files are updated and rotated continuously. An interactive site map is provided below to enable you to see which sites offer raw data before entering the data download area. Real-time/ near real-time plots are also made available for viewing.

These are raw data and have not been through quality control. They may be subject to site malfunctions and may contain spikes and/or gaps. Gaps can be caused by transmission problems so missing values may ultimately be available in the quality controlled banked data.

These data may not be identical to the quality controlled banked data.
