Impact-Based Thresholds for Investigation of High-Tide Flooding in the United States

This directory includes the observational data and model solutions analyzed in Piecuch et al. (2025) "Impact-Based Thresholds for Investigation of High-Tide Flooding in the United States"

data.xls: Spreadsheet with 187 rows and 7 columns. Rows correspond to tide-gauge locations and columns correspond to data fields, which are:* Column 1: Tide-gauge name* Column 2: Tide-gauge region (following Sweet et al. (2022) report)* Column 3: Tide-gauge NOAA ID* Column 4: Tide-gauge longitude* Column 5: Tide-gauge latitude* Column 6: Tide-gauge NWS minor flooding threshold (where available; in m MHHW)* Column 7: Tide-gauge NOS minor flooding threshold (in m MHHW)

thresholds.xls: Spreadsheet with 1000 rows and 187 columns. Columns correspond to the 187 tide-gauge locations detailed in data.xls. Rows contain 1000 values representing the 1000-member posterior solution for minor flood threshold at that tide gauge from the Bayesian model, from which the user can compute summary statistics (e.g., means, medians, standard deviations) or interrogate percentiles and quantiles.

Code used to generate solutions is available at https://github.com/christopherpiecuch/bayesFloodStage/

本数据集目录包含Piecuch等人2025年发表的《美国基于影响的高潮汐洪水调查阈值》研究中所分析的观测数据与模型解算结果。

data.xls：该电子表格共包含187行、7列。行对应验潮站测点，列对应数据字段，具体如下：
1. 第1列：验潮站名称
2. 第2列：验潮站所属区域（遵循Sweet等人2022年发布的报告中的分区标准）
3. 第3列：验潮站美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）编号
4. 第4列：验潮站经度
5. 第5列：验潮站纬度
6. 第6列：验潮站美国国家气象局（National Weather Service, NWS）轻度洪水阈值（若有，单位为米平均高高潮位基准面（Mean Higher High Water, MHHW））
7. 第7列：验潮站美国国家海洋服务局（National Ocean Service, NOS）轻度洪水阈值（单位为米平均高高潮位基准面（Mean Higher High Water, MHHW））

thresholds.xls：该电子表格共包含1000行、187列。列对应data.xls中详述的187个验潮站测点，每行包含1000个数值，代表该验潮站轻度洪水阈值的贝叶斯模型1000成员后验解，使用者可据此计算汇总统计量（如均值、中位数、标准差），或对百分位数与分位数进行分析。
