Storms, ozone may play pivotal role in rainforest cloud creation

Some storms transport ozone molecules to the canopy of the rainforest, influencing chemical processes that ultimately affect cloud formation, according to an international research team led by Penn State. The team conducted ...

Wildfires projected to worsen with climate change

Research by environmental scientists at the Harvard School of Engineering and Applied Sciences (SEAS) brings bad news to the western United States, where firefighters are currently battling dozens of fires in at least 11 ...

Plant hedges to combat near-road pollution exposure

Urban planners should plant hedges, or a combination of trees with hedges—rather than just relying on roadside trees—if they are to most effectively reduce pollution exposure from cars in near-road environments, finds ...

NASA scientists scrutinize arctic gas flaring pollution

Flaring of waste natural gas from industrial oil fields in the Northern Hemisphere is a potential source of significant amounts of nitrogen dioxide and black carbon to the Arctic, according to a new NASA study.

Pollen influences optical properties of the atmosphere

Pollen reflects more sunlight than previously known, and makes up to one third of the total amount of aerosol particles in the atmosphere. Aerosol particles influence optical depth which provides a measure of the opacity ...

Simulating nuclear cloud rise anywhere, anytime

For decades, understanding the behavior of a nuclear mushroom cloud was done with careful analysis of observations made during the testing era. Old photos, outdated film and incomplete weather data made precise calculations ...
