Welcome to Davis Vantage Pro 2 Plus.

The weather station in use is the Davis Vantage Pro2, and these pages are updated every 1 minute. The weather station records in UTC time and can be converted to local time by subtracting 5 hours from the time during regular time and 4 hours during daylight savings time (between the second Sunday of March and the first Sunday of November). The meteorological day used at this station ends at midnight UTC.

The station is located on the roof of the University of Toronto's McLennan Physical Labs located here. The weather station is located at 174 m above sea level and 61 m above the street level. Note that the pressure is listed as Station Pressure and is not adjusted to Sea Level Pressure.

This station is part of the University of Toronto Atmospheric Observatory which is also part of a wider research effort led by Professor Kimberly Strong from the University of Toronto.
