Hurricane Ian Storm Surge Modeling Dataset: Wind Forcing Comparison and Hydrodynamic Simulations

Supplementary Datasets for manuscript: "Accurate hurricane wind structure reduces bias in coastal flood and damage estimates" 1. Wind Speed Error Analysis Dataset (wind_speed_errors.zip) This dataset contains a comprehensive analysis of wind speed prediction errors across 12 major historical hurricane events, comparing observed wind speeds at NOAA gauge locations with model estimates from two atmospheric forcing datasets: ERA5 reanalysis and GAHM parametric model. The compressed archive includes CSV files with error metrics and gauge location data, a Python script for error calculation and visualization, and best track files for all 12 hurricane events used in the analysis. 2. Wind Forcing Datasets (Wind_Forcing_Datasets.zip) This dataset contains atmospheric forcing data for Hurricane Ian (2022) in WRF (Weather Research and Forecasting) format, representing the various wind field datasets used to drive the FVCOM hydrodynamic simulations. The archive includes wind forcing data from multiple atmospheric sources: ERA5 reanalysis, GAHM parametric model, CFSR reanalysis, and Holland (2010) parametric model. 3. Modified GAHM Wind Forcing Dataset (GAHM_IAN_2022_modified_wind.zip) This dataset contains modified wind forcing fields for Hurricane Ian (2022) constructed from best track data using the GAHM parametric model. The archive includes four distinct wind field scenarios: two files with wind intensity modified by 25% and 50% respectively, and two files with radius of maximum wind (Rmax) modified by 25% and 50% respectively (the baseline GAHM wind field is provided separately in the Wind_Forcing_Datasets.zip archive). 4. Maximum Water Surface Elevation from Hurricane Ian FVCOM Simulations (max_eta_all_models.nc) This dataset contains maximum water surface elevation (eta) values from FVCOM (Finite Volume Community Ocean Model) simulations of Hurricane Ian's impact on the west coast of Florida. The netCDF file includes maximum water levels computed across six different wind forcing models: Holland (2010), GAHM, CFSR, ERA5, ERA5-OWI, and ERA5-OWI r25. Each model represents different atmospheric forcing datasets applied to the same FVCOM mesh. The dataset is provided on an unstructured triangular grid and includes supplementary grid information (longitude, latitude, and bathymetric depth) for each computational node.论文《精准飓风风场结构降低海岸洪水与灾害评估偏差》补充数据集 1. 风速误差分析数据集（wind_speed_errors.zip） 本数据集包含12场典型历史飓风事件的风速预测误差综合分析，将美国国家海洋和大气管理局（NOAA, National Oceanic and Atmospheric Administration）测站的实测风速，与ERA5再分析资料、GAHM参数化模型两类大气强迫数据集的模型估算风速进行对比。本压缩归档包含存储误差指标与测站位置数据的CSV文件、用于误差计算与可视化的Python脚本，以及本次分析所用全部12场飓风的最佳路径文件。 2. 风强迫数据集（Wind_Forcing_Datasets.zip） 本数据集包含2022年飓风伊恩（Hurricane Ian）的WRF（Weather Research and Forecasting, 天气研究与预报模型）格式大气强迫数据，即用于驱动FVCOM（Finite Volume Community Ocean Model, 有限体积社区海洋模型）水动力模拟的多套风场数据集。本归档包含多源大气强迫数据：ERA5再分析资料、GAHM参数化模型、CFSR再分析资料以及Holland（2010）参数化模型的风场数据。 3. 改进型GAHM风强迫数据集（GAHM_IAN_2022_modified_wind.zip） 本数据集包含基于最佳路径数据、通过GAHM参数化模型构建的2022年飓风伊恩改进型风强迫场。本归档包含4种不同风场情景：分别为风速强度经25%、50%调整的文件，以及最大风速半径（Rmax, radius of maximum wind）经25%、50%调整的文件（基准GAHM风场已单独收录于Wind_Forcing_Datasets.zip归档中）。 4. 飓风伊恩FVCOM模拟所得最大水面高程数据（max_eta_all_models.nc） 本数据集包含2022年飓风伊恩侵袭佛罗里达西海岸的FVCOM模拟结果中的最大水面高程（eta）数值。该netCDF文件包含6种不同风强迫模型计算得到的最高水位结果：Holland（2010）模型、GAHM模型、CFSR模型、ERA5模型、ERA5-OWI模型以及ERA5-OWI r25模型。所有模型均采用同一套FVCOM计算网格，仅大气强迫数据源存在差异。本数据集基于非结构化三角网格构建，包含每个计算节点的补充网格信息（经度、纬度与水深数据）。
