Monitoring and modeling of airborne particulate matter(PM)from low-altitude sources is becoming an important regulatory target as the adverse health consequences of PM become better ***,application of models not specifically designed for simulation of PM from low-altitude emissions may bias *** address this problem,we describe the modification and validation of an air dispersion model for the simulation of lowaltitude PM dispersion from a typical cotton ginning *** found that the regulatory recommended model(AERMOD)overestimated pollutant concentrations by factors of 64.7,6.97 and 7.44 on average for PM 2.5,PM 10,and TSP,*** concentrations were negatively correlated with height(p<0.05),distance from source(p<0.05)and standard deviation of wind direction(p<0.001),and positively correlated with average wind speed(p<0.001).Based on these results,we developed dispersion correction factors for AERMOD and cross-validated the revised model against independent observations,reducing overestimation factors to 3.75,1.52 and 1.44 for PM 2.5,PM 10 and TSP,*** reductions in model error may be obtained from use of additional observations and refinement of dispersive correction *** generally,the correction permits the validated adjustment and application of pre-existing models for risk assessment and development of remediation *** same approach may also be applied to improve simulations of other air pollutants and environmental conditions of concern.
