Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. But it not directly measurable from space, due to the abundance of ozone higher in the atmosphere, which masks the surface. Now, researchers have devised a way to use satellite measurements of the precursor gases that contribute to ozone formation to predict when and where ozone will form.
By the Numbers: Air Quality and Pollution in New York City
New York City is known for many things, but having clean air isn’t one of them. Explore some of the issues and challenges the Big Apple faces in clearing NYC’s air through interactive maps and data.
The new global environmental report card is out. The 2016 Environmental Performance Index graded 180 countries on how well they are protecting human health and their ecosystems. While the world is making progress in some areas, it is seriously falling behind in others.
The Earth Institute will offer nine research assistant opportunities for undergraduate students during the Spring 2016 semester.
Looking at regional differences in PM2.5 concentrations gives us a sense of the changing face of air quality throughout the world.
A new study shows that ozone pollution in the western United States can be increased by La Niña, a natural weather cycle at the surface of the Pacific Ocean. The finding is the first to show that the La Nina-El Nino cycles directly affects pollution.
While not all countries have the financial wherewithal and capacity to deploy ground-based instruments for air-quality monitoring, and for some countries monitoring information is not available to the public, for example, through health advisories, another way exists to assess air pollution levels: through satellites.
