Measurements from satellites this year showed the hole in Earth's ozone layer that forms over Antarctica each September was the smallest observed since 1988.

Atmospheric researchers depart this month on NASA's DC-8 research aircraft on their third survey of the global atmosphere.

Video Series: Essential Climate Variables

The European Space Agency has released this series of videos that focus on Essential Climate Variable's including Greenhouse Gases, Fires, Clouds, Ozone, Sea Surface Temperatures to help us better understand our changing world.

The 2015 Antarctic ozone hole area was larger and formed later than in recent years, said scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA).

The Antarctic ozone hole, which typically reaches its annual peak area between mid-September and early October, formed more slowly this year.

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.

NASA research shows Earth's atmosphere contains an unexpectedly large amount of an ozone-depleting compound from an unknown source decades after the compound was banned worldwide.

New Results From Inside the Ozone Hole

NASA scientists have revealed the inner workings of the ozone hole that forms annually over Antarctica and found that declining chlorine in the stratosphere has not yet caused a recovery of the ozone hole.

The ozone hole that forms each year in the stratosphere over Antarctica was slightly smaller in 2013 than average in recent decades, according to NASA satellite data.

For the past decade, ESA's Mars Express orbiter has been observing atmospheric structure on the Red Planet. Among its discoveries is the presence of three separate ozone layers, each with its own characteristics. A new comparison of spacecraft data with computer models explains how global atmospheric circulation creates a layer of ozone above the planet's southern winter pole.
