CMAQ预报数据的管理与订正分析

Analysis on the Management and Rivision of Forecasting Data of CMAQ

"CMAQ产品数据管理与分析系统"是通过污染物的历史监测值和CMAQ的预报值建立数据库进行统一管理,利用历史的污染物监测数据,采用多种统计学方法对CMAQ预报值进行订正,目的是解决CMAQ模式存在的染浓度预报量与实况相比明显偏低的"系统性"误差的问题。

＂The data management and analysis system of CMAQ product＂ monitors historical numerical value of pollutants and CMAQ＇s value of forecasting for unified management through the establishment of databases, uses several statistical methods, to revise CMAQ＇s forecast value. The purpose is to solue the problem of difference existing in the CMAQ mode that the forcasting value of the polluution concentration is obviously less than practical situagion.
