NOAA High Tide Flooding Products for U.S. Coastal Stations

NOAA's Center for Operational Oceanographic Products and Services (CO-OPS) has gathered oceanographic data for over 200 years. The suite includes historical summaries and outlooks for high tide flooding at specific coastal stations, helping communities plan for coastal flood impacts. The data is provided in PDF and HTML formats.

Use Cases

• Analyze historical high tide flooding frequency based on station-specific summaries.
• Forecast short-term coastal flood risk based on the Monthly and Annual HTF Outlooks.
• Model long-term infrastructure vulnerability based on recurrent flooding patterns described.
• Assess regional sea-level rise impacts based on the increase in sunny-day flooding events.

Strengths

• Data originates from NOAA CO-OPS, described as the authoritative source for water-level measurements.
• Data collection spans over 200 years, suggesting a long-term historical record.
• Products are designed for specific stations, indicating localized detail.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Primary file formats are PDF and HTML, which may require extraction for computational analysis.
