Aerosols are a critical factor in the atmospheric hydrological cycle and radiation budget. As a
major agent for clouds to form and a significant attenuator of solar radiation, aerosols affect …

New particle formation of liquid or solid nanoparticles from gas-phase precursors is a
decisive process in Earth's atmosphere and is considered one of the largest uncertainties in …

We present a method to describe the relationship between particle dry diameter and cloud
condensation nuclei (CCN) activity using a single hygroscopicity parameter κ. Values of the …

Abstract The 1999 Regional Haze Rule provides a context for this review of visibility, the
science that describes it, and the use of that science in regulatory guidance. The scientific …

The effects of atmospheric aerosol on climate forcing may be very substantial but are
quantified poorly at present; in particular, the effects of aerosols on cloud radiative …

In recent years, severe haze events often occurred in China, causing serious environmental
problems. The mechanisms responsible for the haze formation, however, are still not well …

Understanding the properties of clouds in the Earth's atmosphere is currently limited by
difficulties at the fundamental level of adequately describing the processes of cloud droplet …

Aerosols are formed, evolve, and are eventually removed within the general circulation of
the atmosphere. The characteristic time of many of the microphysical aerosol processes is …

Almost every home and office contains a portrayal of a scenic landscape whether on a
calendar, postcard, photograph, or painting. The most sought after locations boast a scenic …

In this paper we summarize recent experimental, theoretical and observational results on the
formation and growth of atmospheric nanoparticles. During the last years significant …
