Tropospheric anthropogenic aerosols contribute the second-largest forcing to climate
change, but with high uncertainty owing to their spatio-temporal variability and complicated …

Aerosols interact with radiation and clouds. Substantial progress made over the past 40
years in observing, understanding, and modeling these processes helped quantify the …

The cloud droplet number concentration (N d) is of central interest to improve the
understanding of cloud physics and for quantifying the effective radiative forcing by aerosol …

Aerosol–cloud interactions (ACIs) are considered to be the most uncertain driver of present-
day radiative forcing due to human activities. The nonlinearity of cloud-state changes to …

The cooling of the Earth's climate through the effects of anthropogenic aerosols on clouds
offsets an unknown fraction of greenhouse gas warming. An increase in the amount of water …

The impact of aerosols on cloud properties is one of the largest uncertainties in the
anthropogenic radiative forcing of the climate. Significant progress has been made in …

Anthropogenic aerosols are hypothesized to enhance planetary albedo and offset some of
the warming due to the buildup of greenhouse gases in Earth's atmosphere. Aerosols can …

Suspended aqueous aerosol droplets (< 50 µm) are microreactors for many important
atmospheric reactions. In droplets and other aquatic environments, pH is arguably the key …

Aerosols cool Earth's climate indirectly by increasing low cloud brightness and their
coverage (Cf), constituting the aerosol indirect forcing (AIF). The forcing partially offsets the …

This article discusses some of the challenges that have limited progress in quantifying the
radiative forcing associated with aerosol–cloud interactions (ACI) in warm (liquid-water) …
