Ubiquitous carbon-rich aerosol particles created by emissions from cars, trees, and other sources alter our climate and affect air quality. Until recently, the properties of these aerosols were hard to experimentally characterize, ...
Aerosol particles in the Earth's atmosphere scatter and absorb light differently at different wavelengths, thereby affecting the amount of incoming sunlight that reaches the planet's surface and the amount of heat that escapes, ...
It's easy to visualize particles and gases from vehicle exhaust or burning trash wafting into the atmosphere. It's harder to envision similar gases and minute particles emitted from trees and plants in the forest. What these ...
Sensitive, yet tough. That's nanoDESI. The nanospray Desorption ElectroSpray Ionization technique, a novel method created at Pacific Northwest National Laboratory to analyze tiny samples of atmospheric aerosols. This new ...
An aerosol mass spectrometer developed by chemists from Aerodyne Research Inc. and Boston College is giving scientists who study airborne particles the technology they need to examine the life cycles of atmospheric aerosols ...
A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases – sunlight blocked by dust, pollution and other aerosol particles – appears to have lost ground.
Pinpointing pollutant sources is an important part of the ongoing battle to improve air quality and to understand its impact on climate. Scientists using NASA data recently tracked the path and distribution of aerosols -- ...
There seems to be something new under the sun -- in the sky, specifically -- that could complicate scientists' efforts to get a fix on how much the world will warm in the future. Greenhouse gases are not the only things in ...
NASA scientists and two research aircraft are on their way to a unique natural laboratory off the Atlantic coast of southwest Africa to study a major unknown in future climate prediction.
NASA scientists and engineers are working now to lay the groundwork for the Aerosol-Cloud-Ecosystem (ACE) mission, a satellite that will dramatically change what we can do from space to learn about clouds and aerosols.
