Abstract |
Previous studies of the National Crop Loss Assessment Network (NCLAN) relating the impact of ozone (O3) on agricultural crops have used the seasonal arithmetic average of O3 for either a 7- or 12-h daily period as the measure of dose in the dose response relationships. The study investigated the use of alternative dose metrics that gave differential weighting to hourly O3 concentrations according to level of O3, period of day, or total hourly solar radiation. Data were used from two NCLAN studies in which two different methods of O3 addition were used for 7 h/d. In addition, one study included 12 h/d exposure for one method of O3 addition. The residual sums of squares from fitting a common Weibull response model to each experiment were compared over the range of dose metrics. Weighting by total hourly solar radiation gave results very similar to the best obtained from differential peak-valley weighting and 7 h:5 h weighting. |
