SciSat 1

SciSat 1 [CSA]

SciSat 1 (Science Satellite 1) is an atmospheric research satellite to improve the understanding of the depletion of the ozone layer, with a special emphasis on the changes occurring over Canada and in the Arctic.

It will carry two primary instruments:

• Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) and
• Measurements of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation (MAESTRO).

The scientific goal of the ACE (Atmospheric Chemistry Experiment) experiment is to measure and understand the chemical processes that control the distribution of ozone in the Earth's atmosphere, particularly at high latitudes. The measurements obtained will be combined with data gathered by ground-based, balloon-based and other space-based projects in order to obtain the best possible information to predict future trends relating to the ozone layer and its depletion. The data, recorded as SCISAT-1 orbits the Earth, will provide Canadian and international scientists with improved measurements relating to global ozone processes and help policy makers assess existing environmental policy and develop protective measures for improving the health of our atmosphere. The ACE mission is designed to last at least two years.
