We describe the digitization of 1.8 million sub‐daily and daily weather observations which were recorded in the UK Met Office Daily Weather Reports during the 1900–1910 period. The data were rescued from scanned images of the original documents by 2,148 volunteer citizen scientists using the weatherrescue.org website. The rescued observations include dry and wet bulb temperatures, daily maximum and minimum temperatures, daily rainfall amounts and sub‐daily sea‐level pressure from 72 different locations across western Europe. These observations will be used to fill gaps in existing pressure, temperature and rainfall records and are one of the largest recoveries of weather data by citizen scientists. The value of these additional observations is highlighted by comparing the pressure observations to the Twentieth Century Reanalysis version 3 ensemble for some specific case studies.

使用公民科学家志愿者将1900-1910年美国气象局日常天气报告中的观测结果数字化

我们描述了1900-1910年间英国气象局每日天气报告中记录的180万个次日和每日天气预报的数字化。该数据是由2148位自愿公民科学家使用weatherrescue.org网站从原始文档的扫描图像中获取的。获救的观测资料包括来自西欧72个不同地点的干球和湿球温度，每日最高和最低温度，每日降雨量和次日海平面压力。这些观测将用于填补现有压力，温度和降雨记录中的空白，是公民科学家对天气数据的最大回收之一。
