Exceedance probability statistics: The likelihood that coastal water levels will reach extreme elevations

摘要

The Center for Operational Oceanographic Products and Services (CO-OPS) has developed a web-based product (http://tidesandcurrents.noaa.gov/est) to provide online access to exceedance probability statistics at approximately 110 long-term National Water Level Observation Network (NWLON) stations. Each of these stations has at least 30 years of data. The analysis is based on the observed monthly extreme water levels tabulated for the period of record for each station.
