The issue of air pollution from particulate matter (PM) is getting worse as more and more
people move into urban areas around the globe. Due to the complexity and diversity of …

Urban air pollution is a serious worldwide problem due to its impact on human health. In the
past 60 years, growing evidence established a correlation between exposure to air …

Atmospheric new particle formation (NPF, via gas-to-particle conversion) occurs commonly
in the troposphere which has implications for air quality, weather, and climate. Here, we …

The present study investigates the particle number concentrations and size distributions in
the ultrafine and fine-sized regimes over a polluted megacity, New Delhi (28.75° N, 77.12° …

Recent development in lightning discharges including transient luminous events (TLEs) and
global electric circuit are discussed. Role of solar activity, convective available potential …

Ultra fine particles (UFP) cover the size range of both nucleation mode particles (NUC, D p<
25 nm) and Aitken mode particles (AIT, 25 nm< D p< 100 nm), and play important roles in …

To understand the very first steps of atmospheric particle formation and growth processes,
information on the size where the atmospheric nucleation and cluster activation occurs, is …

Abstract Number-size distribution is one of the important microphysical properties of
atmospheric aerosols that influence aerosol life cycle, aerosol-radiation interaction as well …

Atmospheric new particle formation (NPF), via gas-to-particle conversion, is the largest
source of aerosol numbers to the terrestrial atmosphere. NPF produces about half of the …

While the formation of new atmospheric aerosol particles and their subsequent growth have
been observed under diverse environmental conditions globally, such observations are very …
