CoSMoS (Coastal Storm Modeling System) Southern California v3.0 Phase 2 flood-hazard projections: average conditions in Ventura County

Geographic extent of projected coastal flooding, low-lying vulnerable areas, and maxium/minimum flood potential (flood uncertainty) associated with the sea-level rise and storm condition indicated.
The Coastal Storm Modeling System (CoSMoS) makes detailed predictions (meter-scale) over large geographic scales (100s of kilometers) of storm-induced coastal flooding and erosion for both current and future sea-level rise (SLR) scenarios. CoSMoS v3.0 for Southern California shows projections for future climate scenarios (sea-level rise and storms) to provide emergency responders and coastal planners with critical storm-hazards information that can be used to increase public safety, mitigate physical damages, and more effectively manage and allocate resources within complex coastal settings.
Model details and data sources are outlined in CoSMoS_3.0_Phase_2_Southern_California_Bight:_Summary_of_data_and_methods (available at https://www.sciencebase.gov/catalog/file/get/5633fea2e4b048076347f1cf?name=CoSMoS_SoCalv3_Phase2_summary_of_methods.pdf). Phase 2 data for Southern California include flood-hazard information for the coast from the border of Mexico to Pt. Conception. Several changes from Phase 1 projections are reflected in many areas; please read the Summary of methods and inspect output carefully. Data are complete for the information presented.

本数据集涵盖了与给定海平面上升及风暴情景相关的、经预测的沿海洪水、低洼易受影响区域，以及最大/最小洪水潜势（即洪水不确定性）的地理分布范围。沿海风暴模拟系统（Coastal Storm Modeling System, CoSMoS）可在数百公里的大地理尺度上，以米级精度对当前及未来海平面上升（sea-level rise, SLR）情景下的风暴诱发沿海洪水与侵蚀开展精细化预测。针对南加州的CoSMoS v3.0版本，其未来气候情景（含海平面上升与风暴过程）的预测结果，可为应急响应人员与沿海规划者提供关键的风暴灾害信息，助力提升公共安全、减轻物理损失，并在复杂沿海区域更高效地开展资源管理与调配工作。模型细节与数据来源详见《CoSMoS_3.0_Phase_2_Southern_California_Bight: Summary of data and methods》（可从https://www.sciencebase.gov/catalog/file/get/5633fea2e4b048076347f1cf?name=CoSMoS_SoCalv3_Phase2_summary_of_methods.pdf获取）。南加州第二阶段数据覆盖了从墨西哥边境至康塞普西翁角的沿海洪水灾害信息。相较于第一阶段预测结果，本数据集在诸多区域体现出多项更新优化，请仔细阅读方法总结文档并核查输出结果。本次发布的数据已完整覆盖所呈现的全部信息。
