Welcome to the homepage for the Atmospheric Chemistry Experiment
The Atmospheric Chemistry Experiment (ACE) is a satellite mission on-board the Canadian satellite SCISAT that takes measurements of the Earth's atmosphere.
The measurements consist of spectra and images that are used to investigate chemical and dynamical processes in our atmosphere, with a particular emphasis on ozone depletion in the Arctic stratosphere.
Dr. Peter Bernath from the Department of Chemistry at the University of Waterloo is the Mission Scientist.
