Human activities are releasing tiny particles (aerosols) into the atmosphere. These human-
made aerosols enhance scattering and absorption of solar radiation. They also produce …

This paper reviews the many developments in estimates of the direct and indirect global
annual mean radiative forcing due to present‐day concentrations of anthropogenic …

This report is the first complete assessment of the science of climate change since Working
Group I (WGI) of the IPCC produced its second report Climate Change 1995: The Science of …

Aerosol radiative forcing is a critical, though variable and uncertain, component of the global
climate. Yet climate models rely on sparse information of the aerosol optical properties. In …

Measurements and models show that enhanced aerosol concentrations can augment cloud
albedo not only by increasing total droplet cross-sectional area, but also by reducing …

Every year, from December to April, anthropogenic haze spreads over most of the North
Indian Ocean, and South and Southeast Asia. The Indian Ocean Experiment (INDOEX) …

Aerosols affect the Earth's energy budget directly by scattering and absorbing radiation and
indirectly by acting as cloud condensation nuclei and, thereby, affecting cloud properties …

Tropospheric aerosol particles originate from man-made sources such as urban/industrial
activities, biomass burning associated with land use processes, wind-blown dust, and …

We have determined the solar spectral absorption optical depth of atmospheric aerosols for
specific case studies during several field programs (three cases have been reported …

The International Global Atmospheric Chemistry Program (IGAC) has conducted a series of
Aerosol Characterization Experiments (ACE) that integrate in situ measurements, satellite …
