利用逆温参数构建环境空气质量统计预报模型
Constructing Statistical Forecast Model for Ambient Air Quality by Using Temperature Inversion Parameter
摘要
Abstract
The temporal variation pattern of temperature inversion at low altitude in the downtown of Panzhihua is materially correlated with the changes in urban ambient air quality.In this paper,observations of temperature inversion and monitoring data of ambient air quality in Panzhihua was used,with the temperature inversion parameters and hourly concentration of ambient air pollutants at 20:00 of one day taken as independent variables,and the daily average concentration of ambient air pollutants on the next day taken as the dependent variable,to building an ambient air quality forecast model with the multiple regression method.The prediction results of ambient air quality from January to May 2024 showed that among six ambient air pollutants,CO had the highest standard mean error(NME)(24%)between predicted and measured values,and O3 had the lowest NME(9%).The minimum correlation coefficient R was 0.317 for SO2,0.686 for CO,and greater than 0.7 for other ambient air pollutants.The research results indicated that as the temperature inversion parameters more directly reflected the impact of temperature inversion phenomena on ambient air quality under specific regional terrain conditions,building an ambient air quality forecast model based on them can achieve better short-term forecast results and provide more accurate references for experts in numerical forecasting.关键词
