The Atmospheric Chemistry Experiment (ACE) mission is aboard the Canadian SCISAT satellite, one of Canada's first scientific satellites for atmospheric sounding in over 40 years. The ACE payload is comprised of two instruments: the ACE Fourier Transform Spectrometer (ACE-FTS) and Measurement of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation (MAESTRO).

The University of Toronto team are responsible for the MAESTRO instrument health and operations as well as conducting validation for the ACE-FTS instrument.

On this website you can find an introduction to the University of Toronto team, a description of the ACE mission and the MAESTRO instrument and information on the data analysis and validation of the data.
