Observational Evidence For The Impact of the Lake Breeze Circulation on Ozone Concentrations in Southern Ontario

DSpace/Manakin Repository

A YorkSpace software upgrade is planned for Tuesday July 26th, 2016. While only a few minutes of downtime are expected, we ask that all users refrain from using the YorkSpace platform on Tuesday July 26th to ensure that no work is lost. Thanks very much for your patience.

dc.description.abstract Very rapid increases in the concentrations of ozone and ozone precursors, in the late afternoon, have been observed at a rural and an urban site in southern Ontario. Ozone concentration increases of 30 ppbv in a few minutes have been observed. These increases occur simultaneously with the arrival of a Lake Ontario lake breeze front as identified from meteorological measurements and visible satellite imagery. This indicates that polluted air masses from over Lake Ontario are being transported inland by the lake breeze. Aircraft measurements of ozone, NOx, and hydrocarbons show such an air mass moving inland. Chemical measurements at the sites show that the polluted air masses are not of local origin, but are of similar age to those regularly encountered in rural areas en
