Abstract
The National Crop Loss Assessment Network (NCLAN) began in 1980 to coordinate research on the investigation of the impact of ozone on agricultural crops. A major objective was to develop dose-response relationships between yield of major agricultural crop species and ozone pollution in order to estimate the economic effects of ozone. The paper reports on the statistical methodologies used in combining the dose-response information for each species over sites and years, and serves as a summary of the ozone dose-response relationships obtained from the NCLAN studies. All dose-response relationships between yield and ozone were characterized with the polynomial response function and the nonlinear Weibull response function. The paper presents the general methodology for both models and the dose response equations for the Weibull model.
