Abstract Ozone concentrations in the lower troposphere have been measured during the summers of 1999 and 2000 at Peterborough, Ontario (44°N, 78°W) using a novel ground‐based, Fourier‐transform infrared remote‐sensing technique. These concentrations have been compared to temporally overlapping surface ozone amounts measured with a standard TECO ozone analyzer. The comparison showed that there was a significant difference of about 150% in the concentrations measured at the surface and in the boundary layer, especially during the morning hours between 08:30 and 09:30 (EDT). The relationship between ozone concentrations at the surface and in the lower troposphere during the afternoon was less obvious due to the smaller number of measurements taken and the variation of the results. This work may have important consequences concerning air pollution models that normally use ground‐level ozone concentrations as a model input parameter. Copyright © 2005 John Wiley & Sons, Ltd.
