The many hardships, privations, and disruptions endured by Kentuckians during the Civil War were exacerbated by the extremely wet and dry spells of Kentucky's climate. These weather conditions are known because the Smithsonian Institution was collecting climate data during the war years. The Smithsonian's climate network was created in 1847. Seven years later, it had observers reporting from Kentucky and each of the other thirty states. By 1860, the Smithsonian Institution had supplanted the Army's network as the primary climatic data collection agency for the United States. During the Civil War, ten stations reported from Kentucky. Springdale, the Army Post at Newport, and Pine Grove reported for the entire period. The other seven stations reported for shorter periods. These records present a description of the daily weather in central Kentucky and information about the hardships that it imposed.
