ACE data appears in the 2022 Scientific Assessment of Ozone Depletion.
Sulfate aerosols from the Tonga volcano are detected from 60 degrees North to 60 degrees South. A paper has been published in the Journal of Quantitative and Radiative Transfer.
A new study shows that smoke from wildfires destroys the ozone layer. Researchers caution that if major fires become more frequent with a changing climate, more damaging ultraviolet radiation from the sun will reach the ground.
Large wildfires inject smoke and biomass-burning products into the mid-latitude stratosphere, where they destroy ozone, which protects us from ultraviolet radiation.
Using data from the Canadian Space Agency’s (CSA) SCISAT satellite, atmospheric scientists from the University of Waterloo have confirmed that certain clouds draw pollution away from the surface of Earth.
Launched by NASA on board the Canadian satellite SCISAT in 2003, the Atmospheric Chemistry Experiment (ACE) was intended for a two-year mission. Fifteen years later, ACE is still providing excellent spectra that provide vital chemical and physical data about our atmosphere, particularly the ozone layer.
SCISAT was originally designed for a 2-year mission but has now surpassed expectations and continues to record measurements of Earth's atmosphere. To commemorate this special occasion, a tenth anniversary book has been published entitled The Atmospheric Chemistry Experiment ACE at 10: A Solar Occultation Anthology.
A team from the Department of Chemistry at the University of York (York, UK) is involved in monitoring emissions using aircraft and satellites. Their mission is to gather data on the extent to which the fires affect levels of atmospheric pollutants such as ozone and the way those pollutants interact.
Unusually low temperatures in the Arctic ozone layer have recently initiated massive ozone depletion. The Arctic appears to be heading for a record loss of this trace gas that protects the Earth's ssurface against ultraviolet radiation from the sun.
Scientists at the University of York have played a key role in new international research which demonstrates how one of the world's great natural phenomena is helping to increase pollution in the upper atmosphere.
