【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。更多还原

【Abstract】 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.更多还原
