Researchers Use Satellites To Track Smog From Space
2012-11-27 17:16:51

Michael Harper for redOrbit.com — Your Universe Online As it turns out, measuring pollution from the ground can be a tough task. Smog, in particular, can be hard to track. This thick, dirty cloud is often found over the world´s megacities, with populations over 2 million. Scientists have placed monitoring stations in these cities in an attempt to monitor smog levels, but they aren´t always accurate. The placement of these monitoring stations is crucial, and they...

Amazon Rainforest Clouds Created By Salt

April Flowers for redOrbit.com - Your Universe Online Early morning, deep in the Amazon jungle, fog drifts through the still air. The sun rises and clouds appear to float across the forest canopy. Where do these clouds and mists come from? Water vapor needs soluble particles to condense on, and airborne particles are the seeds of liquid droplets in fog, mist and clouds. To learn how aerosol particles form in the Amazon, an international team of scientists analyzed samples of...

Summer contest aims to raise awareness about air quality in the region Pittsburgh, PA (PRWEB) August 14, 2012 A summer contest offers residents of Pennsylvania the chance to win prizes for guessing when the Steel City´s “First Clean Air Day of Summer” will occur. Much like a television weatherman might ask viewers to pick the first snow day of the year, the contest asks people to submit their guess for the First Clean Air Day of Summer. The contest is part of an ongoing...

Sulfur dioxide emissions from shipping have sharply decreased in EU ports thanks to an EU policy which limits sulfur content in fuels for ships at berth or at anchor in ports. Scientists at the European Commission's Joint Research Centre measured key air quality parameters in Mediterranean harbors before and after the entry into force of the low-sulfur requirements in January 2010. In European harbors they found an average decrease of 66% in concentrations of sulfur dioxide, a chemical...

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....
