HIFLD OPEN Tsunami Capable Tide Stations

NCEI is the long-term archive for all NOAA coastal tide gauge data: 1-minute water level data from the NOAA/National Ocean Service (NOS) Center for Operational Oceanographic Products and Services (CO-OPS) and high-resolution (10-second or 15-second) water level data from the Pacific Tsunami Warning Center (PTWC) and the National Tsunami Warning Center (NTWC). Coastal tide gauge data also undergo quality control and harmonic analysis at NCEI. The raw data and products are discoverable via the Map, Timelines, and THREDDS Data Server links. Data are provided as netCDF and as gzipped comma-separated-values (CSV). More information about tsunami-capable tide gauge data at NCEI
