The science of thunderstorms – thunder, lightning, and chemical reactions

Having already looked at the chemistry behind the smell of rain, here’s a look at some of the science behind thunderstorms. How does lightning happen, what gives it its blue-violet tinge, and what does it have to do with plant growth? more

The Chemical Compounds Behind The Smell Of Rain

Everyone’s familiar with the smell after a heavy rain shower in the summer – or, for that matter, the ominous scent of an oncoming thunderstorm. In the third part of the Aroma Chemistry series, this graphic examines the chemical compounds that are the major contributors to these smells, and how they more

A Brief Guide to Atmospheric Pollutants

Back in school, you’ll have learned that the air in our atmosphere is composed primarily of nitrogen, at 78%, and oxygen, at 21%, with a number of other trace gases. It’s to these trace gases we’re looking today – more specifically, at how human activity can result in the release of air pollution in more
