Volcanoes cause climate gas concentrations to vary
Trace gases and aerosols are major factors influencing the climate. With the help of highly complex installations, such as MIPAS on board of the ENVISAT satellite, researchers try to better understand the ...
When pollution gets a whiff of trees: City and tree emissions mix it up causing poor air quality
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 ...
Dust dries clouds by gobbling up water vapor: Scientists show how different cloud seeds can influence greenhouse effect
(Phys.org)—High in the atmosphere, cold and wispy cirrus clouds are the setting for a climate competition. Researchers at Pacific Northwest National Laboratory found that dust particles in the atmosphere ...
Influence of cosmic rays on cloud droplet formation explored in a global climate model
A research team from the State University of New York-Albany and Pacific Northwest National Laboratory used a global atmospheric model to estimate that charged ions produced by cosmic rays in the atmosphere ...
When clouds hang out with pollution: Clean-sky clouds more susceptible to pollution's pressure, research finds
Clouds are influenced by the company they keep. Scientists at Pacific Northwest National Laboratory and the National Center for Atmospheric Research (NCAR) found that ocean-hugging clouds in clean regions ...
Disposition to form ice crystals is measured and modeled for a new framework
(Phys.org)—Instead of dust-bunnies under the sofa, this dust helps form ice crystals that are at the heart of clouds. Researchers at Pacific Northwest National Laboratory used dust's loftier disposition ...
A chemistry tale of two carbons: Field study of urban, natural emissions interacting to affect climate change
(Phys.org)—City carbons and country carbons regularly mix in the atmosphere, but how do they get along? That is essentially the question being tackled by a team of scientists led by researchers at Pacific ...
Cut emissions further or face risks of high air pollution, study shows
Most of the world's population will be subject to degraded air quality in 2050 if man-made emissions continue as usual. In this 'business-as-usual' scenario, the average world citizen 40 years from now will ...
Desert dust intensifies summer rainfall in U.S. southwest
(Phys.org) -- Dust is more than something to be brushed off the furniture. Scientists at Pacific Northwest National Laboratory found that dust kicked up from the desert floor acts like a heat pump in the atmosphere, ...
Scientists 'read' the ash from the Icelandic volcano two years after its eruption
In May 2010, the ash cloud from the Icelandic volcano Eyjafjallajökull reached the Iberian Peninsula and brought airports to a halt all over Europe. At the time, scientists followed its paths using satellites, laser ...
'Warming hole' delayed climate change over eastern United States: study
Climate scientists at the Harvard School of Engineering and Applied Sciences (SEAS) have discovered that particulate pollution in the late 20th century created a "warming hole" over the eastern United Statesthat ...
Taming uncertainty in climate prediction
(PhysOrg.com) -- Uncertainty just became more certain. Atmospheric and computational researchers at Pacific Northwest National Laboratory used a new scientific approach called "uncertainty quantification," ...
Measuring how climate models calculate the effects of clouds on Earth's warming
Using ten years of data gathered at three unique measurement sites, scientists at Pacific Northwest National Laboratory and Lawrence Livermore National Laboratory found that global climate models are not representing ...
A finger to the wind
Like testing the wind direction before taking flight, researchers led by scientists at Pacific Northwest National Laboratory assessed the meteorological conditions during a large observational study of carbon-containing ...
The proof is in the clouds
For most people, clouds are just an indication of whether it's a "good" or "bad" day. A team of scientists from Pacific Northwest National Laboratory found that certain clouds hold the key to climate behavior ...
