Abstract - Vertical profiles of light-absorbing particles in seasonal snow were sampled from 67 North American sites. Over 500 snow samples and 55 soil samples from these sites were optically...
Abstract - Black carbon (BC) mass emission factors (EFBC; gBC (kgfuel)−1) from a variety of ocean-going vessels have been determined from measurements of BC and carbon diox- ide (CO2)...
Abstract - China is the world’s largest emitter of anthropogenic air pollutants, and measurable amounts of Chinese pollution are transported via the atmosphere to other countries, including...
Increases in Asian aerosol emissions have been suggested as one possible reason for the hiatus in global temperature increase during the past 15 years. We study the effect of sulphur and black...
The Arctic is a region in transformation. Warming in the region has been amplified, as expected from ice-albedo feedback effects, with the rate of warming observed to be ∼0.60 ±...
Abstract - The contribution of trans-Pacific dust estimated from satellite observations has been shown to be 3 times greater than domestic dust in North America throughout the year. Thus, a...
The Northern Hemisphere monsoons are an integral component of Earth’s hydrological cycle and affect the lives of billions of people. Observed precipitation in the monsoon regions underwent...
urrently, HFC-134a (1,1,1,2-tetrafluoroethane) is the most common refrigerant in automobile air conditioners. This high global warming potential substance (100 year GWP of 1370) will likely be...
Abstract - Relationships between prenatal exposure to fine particles (PM2.5) and birth weight have been observed previously. Few studies have investigated specific constituents of PM2.5, which may...
Key Findings – Although the technologies and techniques used in extracting shale gas are understood, more research and information is needed on the potential environmental impacts that could...
