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...

By Carol Rasmussen, NASA Earth Science News Team Simply by breathing, humans have played a small part in the planet-wide balancing act called the carbon cycle throughout our existence. However, in the last few hundred years, we have taken a larger role. Our activities, such as fossil fuel burning and deforestation, are pushing the cycle out of its natural balance, adding more and more carbon dioxide to the atmosphere. Natural processes are working hard to keep the carbon cycle in...

France Offers Free Public Transportation Due To Worst Air Pollution In Years
2014-03-15 07:18:59

redOrbit Staff & Wire Reports - Your Universe Online With most of the country suffering from what is being called the worst air pollution since 2007, several cities in France are making buses, trains and other forms public transportation available free of charge this weekend. According to The Telegraph’s Henry Samuel, Paris, Caen, Grenoble, Reims and Rouen are among the cities that will be waiving public transportation fees over the next few days. The move is being described as an...

Air pollution has been linked to heart disease RIVERDALE, N.J., March 12, 2014 /PRNewswire-iReach/ -- In Wilton, Connecticut, parents have a question for local school officials -- and it's not about academics, extracurricular activities, or test scores. They want to know: Is the air at their children's schools safe? The focus on indoor air quality, while perhaps a non-traditional concern for parents, is increasingly becoming an urgent one, as the perils of poor air quality become...

Four New Ozone-Depleting Gases Discovered In Earth's Atmosphere
2014-03-10 10:15:19

Brett Smith for redOrbit.com - Your Universe Online New research from a European team of scientists has identified four new artificial gases in the atmosphere that are depleting the ozone layer, according to a report published Sunday in the journal Nature Geoscience. The report estimated that nearly 82,000 tons of three newly identified chlorofluorocarbons (CFCs) and one newly found hydrochlorofluorocarbon (HCFC) have been released into the atmosphere. “Our research has shown four...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The holy grail of planetary astronomy is the search for a potentially habitable planet, or even better, one that is shown to already contain life. There are various parameters that are needed in order to ascertain the habitability of worlds, such as whether liquid water can be sustained on its surface. Recent studies, however, have found that identifying some of these characteristics is rather difficult, and we may in fact...

Blending Synthetic Air To Measure Climate Change
2014-02-27 09:59:21

National Physical Laboratory Scientists at the National Physical Laboratory (NPL) have produced a synthetic air reference standard which can be used to accurately measure levels of carbon dioxide and methane in the atmosphere. This will greatly help scientists contribute to our understanding of climate change. A paper published in Analytical Chemistry describes how researchers at NPL have created a synthetic gas standard for the first time, which is comparable to the World...

Surface Analysis Features

The above map looks at what is known as ceilings. The definition of ceilings is the first broken or overcast layer of cloud cover in the atmosphere. For it to be considered a ceiling the clouds need to cover more than half of the sky. If we look at the red circled area we see the numbers of 1 and 2. This tells us that there is a ceiling at 1,000-2,000ft which are in the level of low clouds such as cumulus or stratus. The second is the black circle found in the Dakota’s. Here we are...

Surface Weather Map Features for July 5, 2012

The morning weather map for July 5, shows us the current surface pressure readings. Surface Pressure is very important from a meteorological stand point. We use this to help us identify where our surface pressure centers are just like you see above. Our Low pressure area is over Northeast Colorado and also the High pressure over the Ontario area. Surface pressure is taken hourly from the stations and they are also mostly done on a 24hr basis, however some places will only submit their...

Cumulus-nimbus Clouds
2014-01-11 00:00:00

The image above shows a Cumulus-nimbus cloud that has an anvil top to it. The reason that can be identified is that the cirrus is in place above the center of the storm. The image below does not have an anvil top yet. The anvil top forms on CB clouds after they reach the height in the atmosphere where they begin to feel the upper level winds becoming too strong for them to continue development vertically. The storm on the right has not felt the upper level winds yet, that is why it lacks the...

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...
