Ultraviolet Observations - TO2015 Pan and Parapan American Games

Four ground-based radiometers (ultraviolet radiation instruments) were deployed in the Greater Golden Horseshoe Area in support of the Games. They reported minute-by-minute observations of the ultraviolet (UV) component of sun exposure as defined by the Global Solar UV Index (UVI). The ultraviolet index or UV Index is an international standard measurement of the strength of sunburn-producing UV radiation at a particular place and time.

The readings from these sensors were used to inform the operational forecast program, particularly to provide data for validation of the UV index forecasts from the Environment and Climate Change Canada numerical modelling system.

All data in these datasets are essentially ‘raw’, having undergone only minimal automated Quality Control (QC). 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.
