NOAA CO-OPS stations catalog
List CO-OPS stations. Default type=waterlevels returns the 301 primary National Water Level Observation Network (NWLON) stations covering all US coasts, the Great Lakes, Alaska, Hawaii, and territories (some with continuous records since 1856). Pass type=tidepredictions for the full 3,449-entry prediction catalog (primary stations plus subordinate offsets), type=currents for 88 current-meter stations in PORTS projects, or type=all for the unfiltered upstream set. Optional state 2-letter filter is applied client-side against Sugra's 24-hour in-process catalog cache. Attribution: NOAA CO-OPS Tides and Currents (api.tidesandcurrents.noaa.gov).
