April Flowers for redOrbit.com - Your Universe Online Ten years ago on July 15, NASA launched the Aura satellite aboard a Delta II 7920-10L rocket into a sun-synchronous, near polar orbit approximately 400 miles above the Earth. Aura, which is Latin for "Breeze," has provided a wealth of data over the past decade, including the cause, concentrations and impact of major air pollutants. Aura's four instruments give scientists a comprehensive view of the Earth's atmosphere by measuring...

NASA Images Highlight US Air Quality Improvement
2014-06-27 03:22:56

Kathryn Hansen, NASA Anyone living in a major US city for the past decade may have noticed a change in the air. The change is apparent in new NASA satellite images unveiled this week that demonstrate the reduction of air pollution across the country. After ten years in orbit, the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite has been in orbit sufficiently long to show that people in major US cities are breathing less nitrogen dioxide – a yellow-brown gas that can cause...

University of New Hampshire For more than 40 years, policy makers have been working to reduce acid rain, a serious environmental problem that can devastate lakes, streams, and forests and the plants and animals that live in these ecosystems. Now new research funded by the NH Agricultural Experiment Station (NHAES) at the University of New Hampshire College of Life Sciences and Agriculture indicates that lakes in New England and the Adirondack Mountains are recovering rapidly from the...

Titanium Dioxide Roof Tile Coating Removes Up To 97 Percent Of Smog-causing Nitrogen Oxides
2014-06-05 03:46:21

By Sean Nealon, University of California, Riverside A team of University of California, Riverside’s Bourns College of Engineering students created a roof tile coating that when applied to an average-sized residential roof breaks down the same amount of smog-causing nitrogen oxides per year as a car driven 11,000 miles. They calculated 21 tons of nitrogen oxides would be eliminated daily if tiles on one million roofs were coated with their titanium dioxide mixture. They also...

Leaks From Oil And Gas Operations Confirmed By Airborne Measurements

University of Colorado at Boulder CIRES, NOAA study finds more methane, ozone precursors and benzene than estimated by regulators During two days of intensive airborne measurements, oil and gas operations in Colorado's Front Range leaked nearly three times as much methane, a greenhouse gas, as predicted based on inventory estimates, and seven times as much benzene, a regulated air toxic. Emissions of other chemicals that contribute to summertime ozone pollution were about twice as high...

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research led by NCAR. The detailed study shows that Americans face the risk of a 70 percent increase in unhealthy summertime ozone levels by 2050. Boulder, CO (PRWEB) May 05, 2014 Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research led by the National...

Indoor air pollutants have accumulated over the long winter in homes. Amityville, NY (PRWEB) April 30, 2014 Indoor air has remained stagnant all winter long, and now it’s time to clean it out and get some fresh air inside the home. Enviro-Test is recommending that homeowners test the indoor air quality in their homes to ensure that the air is clean for the spring and summer. During the fall and winter, poor ventilation can cause indoor air pollution to accumulate to dangerous levels....

Acid Rain
2013-04-01 10:21:17

Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...

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....
