空气质量AQI实时发布的改进探讨

摘要:
针对《环境空气质量指数(AQI)技术规定(试行)》(HJ 633-2012)中对空气质量AQI实时发布存在的欠缺,从增加颗粒物1 h浓度的AQI分级浓度限值及颗粒物24 h滑动平均值计算方法改进着手,解决PM2.5和PM10的24 h滑动平均值实时延迟、1 h平均值代替24 h滑动平均值偏高等问题。

Discussion on the Improvement of Real Time Publishing of Air Quality Index

Abstract:
Based on the current shortcomings of the document "technical regulation on ambient air quality index (AQI) (on trial)" regarding the real time publishing of air quality index (AQI),improvements were made to increase the 1 hour particle concentration limit at each AQI rank and to revise the calculating method of the 24 hour moving average of the particle concentration.These modifications readily solve existing problems such as the real time delay of the 24 hour moving average of PM2.5and PM10,and the often higher moving average value when using 1 hour average instead of 24 hour.
Key words:  Air quality  AQI real time publishing  PM10  PM2.5  Glide an average value
