Topic: Nitrogen Dioxide
These recent improvements in air quality have come at a high cost, as communities grapple with widespread lockdowns and shelter-in-place orders as a result of the spread of Coronavirus (COVID-19). «Read the rest of this article» Sections: Technology | No Comments
NASA Science continues from Home Offices, Video Conferencing in response to Coronavirus
With most personnel supporting missions remotely to keep onsite staff at a minimal level in response to Coronavirus (COVID-19), the Agency is moving ahead strongly with everything from space exploration to using our technology and innovation to help inform policy makers. «Read the rest of this article» Sections: Technology | No Comments
American Heart Association says Poor air quality does not offset exercise’s heart benefitsJournal of the American Heart Association Report
“While exercise is known to reduce cardiovascular disease risk; pollution can increase the risk of cardiovascular disease, including heart attacks, asthma and chronic obstructive lung disease,” said Nadine Kubesch, Ph.D., lead author and researcher at the University of Copenhagen in Denmark. ![]() Even in areas with moderate to high levels of traffic pollution, regular physical activity reduced the risk of first and recurrent heart attack.

NASA satellite instruments help detect, track WildfiresNASA’s Jet Propulsion Laboratory
Together, NASA instruments, including a number built and managed by NASA’s Jet Propulsion Laboratory in Pasadena, California, detect actively burning fires, track the transport of smoke from fires, provide information for fire management, and map the extent of changes to ecosystems, based on the extent and severity of burn scars. ![]() The concentration and global transport of carbon monoxide pollution from fires burning in Russia, Siberia and Canada is depicted in this NASA photo created with data from the Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua spacecraft.

NASA to use Spacecraft Orbiting Earth to track Air PollutionWritten by Steve Cole
We are getting close. Air pollution causes an estimated 152,000 deaths a year across the Americas and more than 2 million deaths in the Western Pacific, according to the United Nations. Some parts of the world have a detailed view of local air quality from ground sensor networks and forecast models that generate public alerts. But for much of the world this type of information and warning are not available. ![]() Satellites have documented that human-produced and natural air pollution can travel a long way. This 2014 NASA satellite image shows a long river of dust from western Africa (bottom of image) push across the Atlantic Ocean.

NASA’s Aura spacecraft data reveals Background Ozone in U.S. West a real problemWritten by Alan Buis
The researchers, led by Min Huang of George Mason University, Fairfax, Virginia, used a novel technique that combined data acquired from two instruments on NASA’s Aura spacecraft in the summer of 2008. ![]() In parts of Northern California, background ozone levels already account for more than three-quarters of total ozone, leaving little room for local ozone production if stricter standards go into effect.

Diesel-engine exhaust filter reduces harmful particles by 98 percentMay be beneficial for cardiovascular functions. Inhaling exhaust particles increases the risk of dying from heart and lung diseases. Air pollution, including diesel exhaust as a major contributor, causes 800,000 premature deaths annually in the world, according to the World Health Organization. “This study focused on cardiovascular effects in men exposed in the laboratory to diesel fumes. Equipping diesel-powered vehicles with particle filters could significantly reduce heart disease,” said David E. Newby, M.D., Ph.D., co-senior author of the study and the British Heart Foundation John Wheatley Chair of Cardiology at the University of Edinburgh in Scotland. «Read the rest of this article» Sections: News | No Comments
