该数据集名为Bridgedeck — PRISM Climate Features at Bridge Locations (2000–2023)，是bridgedeck数据集集合的一部分，专门用于美国桥面板劣化研究。它提供了2000年至2023年间，每年在美国本土（CONUS）每个桥梁位置从PRISM 4公里网格化气候栅格中采样的气候特征数据，涵盖温度、降水、冻融循环和季节性极端事件。这些环境因素是导致桥面板劣化的关键驱动因素，主要通过热膨胀、水分渗透和冻融剥落等机制产生影响。数据来源为PRISM Climate Group, Oregon State University，包括年度平均温度和降水数据，以及月最低和最高温度数据。数据模式为每个（桥梁ID，年份）一行，包含平均年温度、年总降水量、冻融月份数、冬季最低温度、夏季最高温度等特征，以及这些特征的5年滚动平均值。覆盖范围仅限美国本土，不包括阿拉斯加、夏威夷和波多黎各。数据集旨在支持桥梁工程和气候影响研究，特别是与基础设施退化和气候变化相关的分析。This dataset, named Bridgedeck — PRISM Climate Features at Bridge Locations (2000–2023), is part of the bridgedeck dataset collection for US bridge deck deterioration research. It provides annual climate features sampled at every CONUS bridge location from PRISM 4 km gridded climate rasters, covering the period from 2000 to 2023. The features include temperature, precipitation, freeze-thaw cycles, and seasonal extremes, which are key environmental drivers of bridge deck deterioration via thermal expansion, moisture infiltration, and freeze-thaw spalling. The source is the PRISM Climate Group, Oregon State University, using annual mean temperature and precipitation data, as well as monthly minimum and maximum temperature data. The schema consists of one row per (bridge_id, year), with columns such as mean annual temperature, total annual precipitation, freeze-thaw months, winter minimum temperature, summer maximum temperature, and 5-year rolling averages of these features. Coverage is limited to CONUS only, excluding Alaska, Hawaii, and Puerto Rico. The dataset is designed to support civil engineering and climate impact studies, particularly in infrastructure degradation and climate change analysis.
