研究PM2.5中NO3-、NO2-、NH4+及其气态前体物HNO3、HNO2、NH3的浓度特征和气-粒平衡关系,对深入认识PM2.5的来源及控制因素具有重要意义.因此,本文利用2012年6—7月在青岛采集的denuder和PM2.5大气样品,分析了其中气态和颗粒态氮组分的浓度.结果发现,青岛大气中HNO3、HNO2和NH3浓度分别为(0.80±0.79) μg·m-3、(0.49±0.59) μg...
Phase partitioning of NHx (gaseous NH3 and particulate NH4 +) in the atmosphere is crucial for the lifetime of NHx during atmospheric transport. Reliable data for gaseous NH3 and NH4 + in aerosols ...
Nucleation experiments starting from the reaction of OH radicals with SO2 have been performed in the IfT-LFT flow tube under atmospheric conditions at 293±0.5 K for a relative humidity of 13–61%. The ...
The physical state of the tropospheric aerosol is largely unknown despite its importance for cloud formation and for the aerosol's radiative properties. Here we use detailed microphysical laboratory m...
Micrometeorological measurements of size-segregated particle number fluxes above Dutch heathlands and forests have repeatedly shown simultaneous apparent emission of particles with a diameter (Dp)<0.1...
A field measurement campaign was carried out over a Dutch heathland to investigate the effect of gas-to-particle conversion and ammonium aerosol evaporation on surface/atmosphere fluxes of ammonia and...
We study the ammonia addition reactions of H2SO4·NH3 molecular clusters containing up to four ammonia and two sulfuric acid molecules using the ab initio method RI-MP2 (Resolution of Identity 2nd orde...
