This dataset contains meteorological observations taken from Ben Nevis and Fort William (1883 -1904). These records were produced as part of the Operation Weather Rescue project. Between 1883 and 1904, detailed meteorological observations were taken at the summit of Ben Nevis (56.80N, 5.00W, 1345m elevation) and in the town of Fort William (56.81N, 5.12W, 13m elevation). Hourly observations include temperature (both wet and dry bulb), rainfall, atmospheric pressure at both locations. Daily observations include minimum and maximum temperatures and rainfall. Additional observations taken at Fort William School during the same period are also included. Units are Celsius for temperature, mm for rainfall and mb for pressure. V2 is the latest version.
