The ozone layer of the lower stratosphere is an extremely diffuse abundance of O3 that absorbs up to 99 percent of incoming ultraviolet solar radiation, thereby creating the conditions that make known life possible. In the ...
Today is the UN's International Day for the Preservation of the Ozone Layer – the perfect opportunity to look at how and why measurements of this molecule are taken from space.
