2023 is the 20th year on orbit for the Canadian Space Agency’s Atmospheric Chemistry Experiment (ACE) satellite, which stands as Canada’s most successful scientific space mission. ACE was launched by NASA in August 2003 and continues to make daily measurements of atmospheric composition.
A news article from Space.com celebrating SCISAT's 20 years in orbit notes that "Scisat tracks changes in the atmosphere that could 'delay the ozone recovery in a warming world."
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.
