The Atmospheric Chemistry Experiment (ACE) is a Canadian satellite mission for remote sensing of the Earth's atmosphere that was launched into a high-inclination (74 degrees), circular low-earth (650 km from the surface) orbit on August 13, 2003. This orbit gives ACE coverage of tropical, mid-latitude, and polar regions, allowing it to study a range of atmospheric processes.

The main goal of ACE is to study the atmospheric chemistry and dynamics that affect stratospheric ozone depletion, but ACE measurements are also being used to study ozone depletion in the Antarctic, the relationship between chemistry and climate change, the atmospheric effects of biomass burning, the effects of aerosols and clouds on the global energy balance, and many other areas of atmospheric science.
