AIR TEMPERATURE, Surface pressure, and others collected from FIXED STATIONS OF CANADA in Canada from 1768-09-11 to 1884-02-29 (NCEI Accession 0304217)

Historical weather journals from across Canada, spanning 1768 - 1884, have been transcribed from handwritten records into machine readable formats. The NORTHERN (Nineteenth-century Overseas Records Transcribed for Historical Environmental Reconstruction in the North) project transcribed nearly 2 million weather observations from 45 locations. The original documents are in archives outside Canada, including the US National Archives and Records Administration (NARA), the National Centres for Environmental Information (NCEI) and the United Kingdom Meteorological Office (UKMO). Observers recorded from three to twenty weather variables, in most cases two or three times daily. Validation procedures are carried out with export files produced in both the original format and in SI units. Observations of pressure, temperature, precipitation, snow depth, cloud cover, cloud type, wind direction and wind force are transcribed along with detailed descriptions of events including fires, floods, ice formation and break up, storms and other weather phenomena.
