The fifth edition of Spectra of Atoms and Molecules (Oxford University Press, 2025) is an invaluable companion for the ACE mission. For example, the book has a chapter on spectra of clouds and aerosols based on ACE data.
ACE-FTS version 5.2 processing ended on Nov. 30, 2024 and has been replaced by v5.3. This version change was required because of a change in processing computers. A small change was also made in the retrieval code, which has minimized the number of “spikes” in the VMR profiles near 30 km. As in v5.2, v5.3 removes any occultations with spikes at 30 km. About 1500 occultations have been recovered in v5.3. Processing for the Imagers has not changed. ACE-FTS v5.3 winds will be available soon. V5.3 is therefore the current and complete ACE-FTS and Imager processing version and can be viewed at our ACE-FTS v5.3 database. More details are available in the ACE documents.
The Waterloo Region Record published a news article on ACE!
"While other studies measure the gas on the ground or much lower in the atmosphere, this study by the university’s “Atmospheric Chemistry Experiment” (ACE) research group is the only one which uses a satellite to measure it between 11 and 25 kilometres above the globe."
The University of Waterloo published a news report on our research!
"Waterloo study is the first to use satellites to measure HFC-125 in the atmosphere for a more accurate picture of climate change."
On May 22, 2024, Project Scientist Dr. Chris Boone was awarded the Atmospheric Measurement Techniques (AMT) Outstanding Referee Award.

Congratulations Chris!
Recent scientific discoveries reported by the Canadian Space Agency expose a chemical process in the atmosphere through which intense wildfires contribute to ozone layer depletion. These discoveries have been made possible by ABB technology on board the SCISAT satellite.
The Atmospheric Chemistry Experiment has been accepted as a member of the University of Waterloo's Water Institute; ranked among the top water research institutions in the world.
From April 24 to 26, at the United Nations (UN) 12th Meeting of the Ozone Research Managers in Geneva, Canada tabled its report on ozone and ozone-depleting substances. One of the aims is to share the latest findings on greenhouse gas emissions caused by products whose use is restricted or prohibited. Canada's satellite mission SCISAT has been monitoring ozone-depleting gases restricted by the Montreal Protocol on Substances That Deplete the Ozone Layer.
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."
