Lighthouse meteorological data
Although lighthouses might be regarded as ‘land-based’, their obvious proximity to the seas over which they watch the data that generations of lighthouse keepers have accumulated might be fairly regarded as oceanic in character. Part of CORRAL’s brief was to abstract some of these data, focusssing however on late nineteenth century observations (some of the oldest available) and on sites from the Caribbean for which such data are deficient. Data are also included from St. Helena, providing some coverage for one of the remoter and less well-documented and observed oceanic regions.

THE LIGHTHOUSE SITES
The abstracted data are available on this page as a set of Excel files. The sites included are shown in the accompanying maps and include, from the Caribbean:
- Cay Lobos
- Cay Sol
- Watling Island
from the South Atlantic
- St Helena
and from the tropical Pacific
- Malden Island.
THE DATA FILES
The data files contain sub-daily observations of air pressure and temperature keyed by date and time. Remarks columns also note additional information provided by the observers. Where available barometer height and notes on the corrections applied to the readings are also included at the head of each file. The file names indicate the lighthouse sites and the years covered in that data set.
