The surface warming due to emissions of black-carbon aerosols over the second half of the twentieth century has been identified in observations. These findings will inform debate over the climatic effects of controlling such emissions.

Black carbon landing on snow may be accelerating the melting of Himalayan glaciers more than atmospheric soot or even greenhouse gases such as carbon dioxide (CO₂), according to a study.

Measurements of submicron particles by Fourier transform infrared spectroscopy in 14 campaigns in North America, Asia, South America, and Europe were used to identify characteristic organic functional group compositions of fuel combustion, terrestrial vegetation, and ocean bubble bursting sources, each of which often accounts for more than a third o

Distributions and climate impacts of biomass-burning aerosols were simulated by a global aerosol climate model, SPRINTARS, which was fully coupled to a general circulation model. The model included calculations of the direct, semi-direct and indirect effects of aerosols.

Biomass burning is an important source of greenhouse gas emissions, most importantly carbon dioxide (CO2). In this study, we used burnt area estimates derived from the L3JRC product to estimate the CO2 emissions from forests. The results suggested than an average of 2,414 sq.kms is burnt annually.

The seasonal variability of biomass open burning activities in the Greater Mekong sub-region (GMS) with focus on carbon monoxide (CO) and total particulate matter or aerosol (TPM) emissions was investigated in order to document the characteristics of this significant source of air pollutants in the region.

The purpose of this study is to explore whether sustained exposure to vehicular air pollution affects the behavior and activities of children. The prevalence of attention-deficit hyperactivity disorder (ADHD) was assessed in two childhood populations.

Extensive measurements of columnar aerosol optical depth (AOD), composite (MT) and black carbon aero-
sol mass (MB) concentrations were made over the tropical Indian and Southern Oceans as a part of the
Pilot Expedition to the Southern Ocean during the boreal winter. The AOD, MT and MB show large lati-
