Abstract

There is an ongoing debate as to which components of the ambient ozone (O-3) exposure dynamics best explain adverse crop yield reponses. A key issue is regarding the importance of peak versus mid-range hourly ambient O-3 concentrations. While in this paper the importance of peakatmospheric O-3 concentrations is not discounted, if they occur at a time when plants are conducive for uptake, the corresponding importance of more frequently occurring mid-range O-3 concentrations is described The probability of co-occurrence of high O-3 concentrations and O-3uptake limiting factors is provided using coherent data sets of O-3 concentration, air temperature, air humidity, mean horizontal wind velocity and global radiation measured at representative US and German airquality monitoring sites. Using the PLant-ATmosphere INteraction (PLATIN) model, the significance of the aforementioned meteorological parameters on ozone uptake is examined. In addition, the limitations of describing the O-3 exposure for plants under ambient, chamberless conditions by SUM06, AOT40 or W126 exposure indices are discussed. (C) 1998 Elsevier Science Ltd.
