Index of Bright Sunshine Reporting Stations 
in the Province of Ontario 
1. Stations: This index is a list of all the stations in the Province of Ontario which have 
reported bright sunshine data since 1881. While there have been relocations of some of the sta- 
tions, for practical purposes, all the data for each station should be considered as homogeneous. 
2. Location: The precise location of each station in this index is shown in the January issue 
of the Monthly Record during many of the years of record for each station. Alternate station 
Mames and whether or not the record is complete for the year as a whole is shown on the right 
hand side of the index. 
3. Period of Record: The first month where data are available in Meteorological Headquarters 
abstracts is shown as the date on which the station opened. Similarly, the last month of record 
in the abstract is shown as the closed date. Where stations were in operation in July 1958 the 
symbol A has been shown in the proper column. 
4. Bright Sunshine Data: In Canada, bright sunshine is recorded on a Campbell-Stokes recorder. 
By means of a glass sphere, sunshine is focused to produce a burn on a narrow sunshine chart from 
which the observer is able to scale off the number of hours a day on which a bright sun was shin- 
ing. These daily totals, which are scaled off to a tenth of an hour, are added to give the 
monthly total of bright sunshine in hours. The recorder, which is usually placed on a stand, is 
mounted free from all obstructions from horizon to horizon so that no shadows will fall across
