Environment and Climate Change Canada added 40 compact stations, 10 ATMOS stations and 3 standard automated MSC Auto8 stations to the existing networks to form a high-resolution monitoring system across southern Ontario known as the Mesonet. These stations provided both high-density spacing and high-frequency minute-by-minute observations. Standard meteorological variables were reported—atmospheric pressure, wind speed and direction, relative humidity, temperature and precipitation amounts—as well as a new element recorded by a black globe thermometer, used in the evaluation of heat stress on the human body.

The new automated surface weather stations were configured to report every minute, a sharp departure from the standard hourly reporting. The minute-by-minute reporting was successfully implemented at all 53 new automated weather stations in the Mesonet.

All data in these datasets are essentially ‘raw’, having undergone only minimal automated Quality Control (QC) (manual QC of the ATMOS Mesonet data will be posted to the Science Showcase section of the Legacy Archive, when available). The user is referred to an additional Instrumentation Metadata XLS file posted with the Datasets that describes specific data issues that the users must be aware of before using the datasets.

Site photos for all 53 weather stations are available from the Legacy Archive Data Contact.
