National estimates of U.S. storm surge extremes and underlying long-term trends (1950-2020) using spatiotemporal non-stationary Bayesian Hierarchical Modeling

Version 2 contains two updated files from version 1: These files contain updated versions for these two files: Posterior-median estimates of GEV parameters (shape, scale and location) and associated credible interval (CI) values for 208 tide gauge. Posterior-median estimates of GEV parameters (shape, scale and location) and associated credible interval (CI) values for the entire U.S. coastlines NOTE: all data and associated articles (listed below) require proper acknowlement, citation and referencing of all data when directly or indirectly using any archived file listed above.
