CATALOGING ALL AVAILABLE STORM SURGE MEASUREMENTS FOR THE STATE OF NORTH CAROLINA: THE NATIONAL STORM SURGE DATABASE
For the North Carolina prototype, over 1,000 storm surge and HWM data points have been processed using data from 15 hurricanes that have hit the eastern US within the past 56 years. Each storm surge or HWM data point contains attributes including elevation, latitude/longitude, county, type (e.g., debris, mud), quality and collector. Detailed, georeferenced storm characteristics from NOAA NCDC IBTrACS (International Best Track Archive for Climate Stewardship) are also part of the database, and include storm track, wind speed, central pressure, storm diameter, track straightness and storm impact angle. The most significant advantage to this single, digital storm surge repository is the ability to search and query thousands of data points from numerous sources and instantly view the results spatially in ArcGIS. One can search for only high quality data, or, for example a researcher could examine data from all storms with similar meteorology to examine the variability in storm surge values for that category of storm. We hope that this database will become the one-stop-shop for storm surge data in North Carolina, and eventually the entire US.
