data

The subset1 was created by digitizing and curating the seminal report of Amerine and Winkler (1944), which provided grape harvest dates (GHDs), the quality of musts and wines, and wine tasting notes for 148 cultivars from 1935-1941 across five contrasting climatic regions of California. To put this dataset into a climate change context, we collected GHDs and must sugar content (oBrix) records from 1991 to 2018 for four representative cultivars in one of the five studied regions (Napa) in subset2. Finally, we integrated meteorological data of the five regions during 1911-2018 and calculated bioclimatic indices important for grape in subset3. The resulting database is unique and valuable for assessing the fitness between cultivars across environments in order to mitigate the effects of climate change.子集1（subset1）通过数字化处理与整编遴选了Amerine与Winkler（1944年）发表的开创性研究报告，该报告记录了1935年至1941年间，加利福尼亚州5个气候特征迥异的产区内148个葡萄品种的葡萄收获期（grape harvest dates, GHDs）、葡萄汁与葡萄酒的品质，以及葡萄酒品鉴笔记。为将本数据集纳入气候变化研究框架，我们针对5个研究产区之一的纳帕谷（Napa），收集了1991年至2018年间4个代表性葡萄品种的葡萄收获期与葡萄汁糖度（白利度oBrix）记录，构成子集2（subset2）。最后，我们整合了5个产区1911年至2018年的气象数据，并计算得到对葡萄种植至关重要的生物气候指数，形成子集3（subset3）。本整合数据库兼具独特性与应用价值，可用于评估不同葡萄品种在各环境中的适配性，从而缓解气候变化带来的影响。
