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.

Dozens of scientists descended on Sacramento, Calif, in June hoping for what most of us don’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.

The large number of tiny organic aerosols floating in the atmosphere – emitted from tailpipes and trees alike – 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.


Word of the Day
pawl
  • A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
The word 'pawl' probably comes from a Latin word meaning 'stake'.
