Description:
This paper describes an effort to interface the modeled concentrations and other outputs of the Regional Oxidant Model (ROM) as an alternative set of input files to apply in Urban Airshed Model (UAM) simulations. ive different days exhibiting high ozone concentrations during the 1980 ozone season were simulated by the UAM for the New York metropolitan area for a base scenario and for different sets of initial and boundary conditions and winds from the ROM. he methodology of integrating the ROM results into the UAM processor system is discussed. he modeled UAM ozone concentrations are compared with measured values for the various model input data scenarios in assessing the performance of the nested grid modeling approach. he results indicate relatively good agreement over the New Jersey/New York portion of the UAM domain, and an underprediction of ozone levels over Connecticut.
