Picarro Analyzer Took Historic Measurement on Mauna Loa SANTA CLARA, Calif., May 16, 2013 /PRNewswire/ -- Researchers from SCRIPPS studying atmospheric levels at the Mauna Loa Observatory last week recorded the milestone 400 parts per million (ppm) CO(2) concentration using instrumentation from Picarro Inc. The Mauna Loa observatory is a premier atmospheric research facility, and ideal for monitoring climate change due to the undisturbed air and minimal outside influences atop the...
April Flowers for redOrbit.com - Your Universe Online At any given time, nearly one-third of the planet is covered by cirrus clouds – the thin wisps of vapor that trail across the sky – which coalesce in the upper layers of the troposphere, as much as 10 miles or higher above the surface of the Earth. Cirrus clouds cool the planet by reflecting incoming solar radiation, and warm it by trapping outgoing heat. In this way, they influence global climate, so understanding the...
Environmental health experts indicate families may have been breathing in mouse allergens, lead, fungal spores, insect parts, and diesel exhaust NEW YORK, May 8, 2013 /PRNewswire/ -- Most families don't think about what contaminants could be lurking in their indoor air, so environmental health experts put two average homes to the test as part of a new pilot study. Two families - one in New York and one in suburban Los Angeles - were asked to run an air purifier in their homes for two...
HALIFAX, May 8, 2013 /CNW/ - The Honourable Denis Lebel, Minister of Transport, Infrastructure and Communities, Minister of the Economic Development Agency of Canada for the Regions of Quebec and Minister of Intergovernmental Affairs, today announced that the Government of Canada is adopting strict environmental standards to reduce air emissions from ships navigating in Canadian waters. These changes further align Canada's air emission standards with the United States. ...
It is reported by the EPA and EnergyStar.gov that excessive air leakage and old insulation methods often causes the air inside of our homes to be more seriously polluted than the air outside of our homes. Santa Monica, CA (PRWEB) April 30, 2013 It’s proven that indoor air pollutants cause a variety of health problems, including irritation of the eyes, nose, and throat, headaches, dizziness, fatigue, asthma, and even eventually respiratory disease, cancer, and even heart disease. The...
Brett Smith for redOrbit.com - Your Universe Online In 2004, a group of Princeton scientists found trees release the volatile organic compound (VOC) isoprene that reacts in the air to form particulate pollution, or smog. However, the mechanism behind this process wasn't known until a new study from scientists at the University of North Carolina (UNC) was released this week showing how isoprene’s reaction to sunlight leads to the formation of harmful air pollution. After isoprene is...
NASA A NASA-funded sounding rocket mission will launch from an atoll in the Pacific in the next few weeks to help scientists better understand and predict the electrical storms in Earth's upper atmosphere. These storms can interfere with satellite communication and global positioning signals. The mission, called EVEX, for the Equatorial Vortex Experiment, will launch two rockets for a twelve-minute journey through the equatorial ionosphere above the South Pacific. The launch window for...
New research from the University of Southampton has found that working or traveling on an underground railway for a sustained period of time could have health implications. Previously published work suggests that working in environments such as steel mills or welding plants, which are rich in airborne metals, like iron, copper and nickel, can have damaging effects on health. However, little research has been done on the effects of working in an underground railway environment – a...
Long term exposure to air pollution may be linked to heart attacks and strokes by speeding up atherosclerosis, or "hardening of the arteries", according to a study by U.S. researchers published in this week's PLOS Medicine. The researchers, led by Sara Adar, John Searle Assistant Professor of Epidemiology, University of Michigan School of Public Health, and Joel Kaufman, Professor of Environmental and Occupational Health Sciences and Medicine, University of Washington, found that higher...

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...
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...
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...
Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. Celestial mechanics is part of these...
Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...
