Dust And Microbes That Hitch Rides On It Influences Rain And Climate
2014-08-14 03:16:39

American Chemical Society Dusty air blowing across the Pacific from Asia and Africa plays a critical role in precipitation patterns throughout the drought-stricken western US. Today, a scientist will present new research suggesting that the exact chemical make-up of that dust, including microbes found in it, is the key to how much rain and snow falls from clouds throughout the region. This information could help better predict rain events, as well as explain how air pollution from a...

Alan Buis, Jet Propulsion Laboratory and Kimm Fesenmaier, Caltech Of all the factors that influence Earth's changing climate, the effect that tiny particles in Earth's atmosphere called aerosols have on clouds is the least well understood. Aerosols scatter and absorb incoming sunlight and affect the formation and properties of clouds. Among all cloud types, low-level clouds over the ocean, which cover about one-third of the ocean's surface, have the biggest impact on the albedo, or...

Los Alamos National Laboratory Scientists have uncovered key attributes of so-called “brown carbon” from wildfires. Scientists have uncovered key attributes of so-called “brown carbon” from wildfires, airborne atmospheric particles that may have influenced current climate models that failed to take the material’s warming effects into account. The work was described by a collaborative team of researchers from Los Alamos National Laboratory, Carnegie Mellon University and the...

Wildfires Found To Release A Previously Unidentified Type Of Soot
2014-07-08 06:37:19

Alan McStravick for redOrbit.com - Your Universe online Globally, wildfires are responsible for creating veritable ecological wastelands across millions of hectares of land each year. As the effects of climate change have become ever more pronounced over the previous years, we have seen both the number and severity of wildfires increase drastically. As reported on redOrbit last year, the increasing number of wildfires has been sending both carbon monoxide and other toxins streaming into...

Snowballs to Soot: The Clumping Density of Many Things Seems to Be a Standard
2014-06-12 14:37:12

Michael Baum, National Institute of Standards and Technology (NIST) Particles of soot floating through the air and comets hurtling through space have at least one thing in common: 0.36. That, reports a research group at the National Institute of Standards and Technology (NIST), is the measure of how dense they will get under normal conditions, and it’s a value that seems to be constant for similar aggregates across an impressively wide size range from nanometers to tens of meters.*...

Marlene Cimons, National Science Foundation Researchers study water cycle and cloud formation and design computer algorithm models to understand impact In the past, many atmospheric scientists believed that pollen particles probably had a negligible effect on climate because they were so big. In recent years, however, as they began to realize that pollen particles were not as sturdy as they once thought, they have been rethinking their old assumptions. "Pollen can rupture and...

Laboratory chamber walls have been stealing vapors, causing researchers to underestimate the formation of secondary organic aerosol in the atmosphere. A study published April 7 in PNAS Online Early Edition describes how a team of scientists, including researchers from the University of California, Davis, showed that vapor losses to the walls of laboratory chambers can suppress the formation of secondary organic aerosol, which in turn has contributed to the underprediction of SOA in climate...

Sunset Colors In Famous Paintings Used To Estimate Past Pollution Levels
2014-03-26 07:06:50

redOrbit Staff & Wire Reports - Your Universe Online The colors used by legendary artists of the past to depict a sunset could be used to estimate pollution levels in the atmosphere during bygone days, according to research published Tuesday in the open-access journal Atmospheric Chemistry and Physics. Lead author Christos Zerefos, a professor of atmospheric physics at the Academy of Athens in Greece, and his colleagues showed that paintings of famous artists reveal the ash and gas...

Dust Kicked Up In Asia Strengthens Monsoons In India
2014-03-17 10:18:29

Mary Beckman, DOE/Pacific Northwest National Laboratory A new analysis of satellite data reveals a link between dust in North Africa and West Asia and stronger monsoons in India. The study shows that dust in the air absorbs sunlight west of India, warming the air and strengthening the winds carrying moisture eastward. This results in more monsoon rainfall about a week later in India. The results explain one way that dust can affect the climate, filling in previously unknown details about...

long term warming trend

WASHINGTON, March 11, 2014 /PRNewswire-USNewswire/ -- A new NASA study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming. This research hinges on a new and more detailed calculation of the sensitivity of Earth's climate to the factors that cause it to change, such as greenhouse gas emissions. Drew Shindell, a climatologist at NASA's Goddard Institute for Space Studies in New...

Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...

Haze is a type of atmospheric phenomenon where dust, smoke and dry particles in the air obscure the sky's clarity. Haze is created through various activities including farming, traffic pollution,and even wildfires. The World Meteorological Organization (WMO) categorizes the obscuration of the Earth's atmosphere by a list of different types of atmospheric phenomena. One of these is haze. The other classifications are: fog, ice fog, steam fog, mist, smoke, volcanic ash, dust, sand, and snow....
