摘要
介绍了美国国家环保局第三代空气质量模式(Models-3)的主要组成部分:气象模式系统、排放模式系统以及公共多尺度模式系统(CMAQ)。并对郑州市SO2和NO2观测值与Models-3/CMAQ预报值进行对比分析,结果表明:模式可以模拟出郑州市SO2和NO2的同位相变化规律;预报值存在系统性偏低的现象;随着预报时效的延长,对SO2和NO2的预报效果逐渐变差。
The Models-3 of the U.S. Environmental Protection Agency （EPA） is introduced and it contains： the meteorological modeling system, the emission modeling system and the CMAQ modeling system. By comparing and analyzing the observation data and data forecasted by the Models-3/CMAQ of SO2 and NO2 in Zhengzhou, the results indicate ： The model can forecast the rule of SO2 and NO2 primely in Zhengzhou; The forecasting value is systemic lower than the observations; With forecasting time prolonging, the tendency of forecasting for SO2 and NO2 get worse subsequently.
