Latest Stratospheric sulfur aerosols Stories
Scientists have known for decades that black carbon aerosols add to global warming.
NASA is scheduled to launch its latest Earth-orbiting satellite -- Glory -- in the predawn hours early Wednesday in what is to be a $424 million mission to observe and analyze airborne particles emitted from volcanoes, forest fires, smokestacks and tailpipes.
Climatologists have known for decades that airborne particles called aerosols can have a powerful impact on the climate.
A new analysis of sulfur emissions appearing in the journal Atmospheric Chemistry and Physics shows that after declining for a decade, worldwide emissions rose again in 2000 due largely to international shipping and a growing Chinese economy.
Could dimming the sun change teleconnections in weather patterns as we know them?
Dozens of scientists descended on Sacramento, Calif, in June hoping for what most of us donâ€™t want to see during hot summer days: thick, sooty haze.
Haze, scientifically known as atmospheric aerosols - microscopic particles suspended in the Earth's atmosphere - represents a major environmental problem because it degrades visibility, affects human health and influences the climate.
Airplanes, ground instruments, and weather balloons to study effect of airborne particles on climate.
The large number of tiny organic aerosols floating in the atmosphere â€“ emitted from tailpipes and trees alike â€“ share enough common characteristics as a group that scientists can generalize their makeup and how they change in the atmosphere.
NSF-supported climate scientist Mark Flanner and colleagues find differences in the rates for spring warming and snow cover decline in Eurasia and North America, and are studying whether aerosols are a key factor.
