US Naval Observatory Hourly Observations

Hourly observations journal from the National Observatory in Washington DC. The observatory is the first station in the United States to produce hourly observations over a long period. The images were captured from microfilm held at the National Archives and Records Administration (NARA) in College Park, MD. Scanning performed by a Climate Database Modernization Program (CDMP) contractor. Period of record July 1842-February 1913.
