Surface charges on aerosol particles – Accelerating particle growth rate and atmospheric pollution

Lidar and Atmospheric Aerosol Particles

Chinese Growth and Atmospheric Pollution:

This paper uses a dynamic CGE model, calibrated to new and detailed Chinese emissions data, to assess two important questions. What can we reasonably expect Chinese emissions trends to look like over the next two decades? Secondly, what would be the appropriate policy interventions to flatten Chinese emissions trajectories and reduce the risk of local, regional, and even global adversity? This ...

Mode resolved density of atmospheric aerosol particles

In this study, we investigate the mode resolved density of ultrafine atmospheric particles measured in boreal forest environment. The method used here enables us to find the distinct density information for each mode in atmospheric fine particle population: the density values for nucleation, Aitken, and accumulation mode particles are 5 presented. The experimental data was gained during 2 May 2...

Atmospheric new particle formation: real and apparent growth of neutral and charged particles

In this study we have provided simple analytical formulae to estimate the growth rate of a nucleation mode due to self-coagulation and the apparent growth rate due to coagulation scavenging by larger particles. These formulae were used on a set of simulations covering a wide range of atmospheric conditions. The modal growth rates were determined from the simulation results by summing the contri...
