为研究渭南市区2014 — 2016年的冬春季雾霾天气的特点,选取覆盖渭南市区的4个监测站点,分析渭南市区PM10PM2.5污染时间分布特征;同时选取日平均气温、相对湿度、风等气象因素,用线性回归分析法分析各个气象因素同大气中PM10PM2.5的相互关系。研究发现:三年来冬季PM10PM2.5的日变化的峰值主要出现在12月— 次年1月; 春季PM10PM...
2012年7月,对黄石市城区夏季昼间大气颗粒物PM10PM2.5样品进行采集,并用热/光反射法(TOR)分析其中的有机碳(OC)、元素碳(EC).结果显示,新老城区PM10中OC平均含量分别为14.60 μg·m-3和18.70 μg·m-3,EC平均含量分别为4.70 μg·m-3和11.02 μg·m-3;PM2.5中OC平均含量分别为11.89 μg·m-3和13.66 μg·m-3,EC...
Atmospheric aerosols or particulate matters are chemically complex and dynamic mixtures of solid and liquid particles. Sources of particulate matters include both natural and anthropogenic processes. ...
PM10, PM2.5 and PM1 mass concentrations have been measured at Delhi (28°35'N; 77°12'E) during the August to December 2007. The running mean of PM10, PM2.5 and PM1 data shows large variations. The PM1...
The spatial distribution of the aerosols over 86 Chinese cities was reconstructed from air pollution index (API) records for summer 2000 to winter 2006. PM10 (particulate matter ≤10 μm) mass concentra...
We report chemical composition data for PM10 and PM1 from the Nepal Climate Observatory-Pyramid (NCO-P), the world's highest aerosol observatory, located at 5079 m a.s.l. at the foothills of Mt. Evere...
The atmospheric respirable particulate matter (PM10) from four typical districts of Harbin was collected in four seasons. By analyzing the samples, we got the spatial distribution and seasonal variat...
Concentrations of organic carbon (OC) and elemental carbon (EC) in atmospheric particles were measured in Tianjin during January, April, July and October in 2008. The 24-h PM2.5 (particles with aerod...
The PM10 and PM2.5 levels at a highway toll station were monitored from October to December 2008. Experimental results show that hourly average PM10 and PM2.5 levels at the highway toll station were ...
We investigate in this study the vertical PM10 distributions from mobile measurements carried out from locations along the Paris Peripherique (highly trafficked beltway around Paris), examine distinct...
In spite of the strict EU regulations, concentrations of surface ozone and PM10 often exceed the pollution standards for the Netherlands and Europe. Their concentrations are controlled by (precursor) ...
This paper presents experiments of PM10 data assimilation with the optimal interpolation method. The observations are provided by BDQA (Base de Données sur la Qualité de l'Air), whose monitoring netwo...
A Lagrangian trajectory model used to simulate photochemistry has been extended to include a simple parameterisation of primary and secondary aerosol particles. The model uses emission inventories of ...
Inter-comparisons of European air quality models show that regional transport models, including the EMEP (Co-operative Programme for monitoring and evaluation of the long-range transmission of air pol...
