The principal goal of the Atmospheric Chemistry Experiment (ACE) mission is to investigate the chemical processes that are involved in the distribution of ozone in the atmosphere. The ACE mission will work in conjunction with other instruments and missions planned by NASA, the European Space Agency, and other international partners over the next decade to gain a better understanding of the chemistry and dynamics of the atmosphere that affect the Earth?s protective ozone layer. The analysis of the large amount of data that will be collected will lead to a more informed assessment of international environmental policies such as the Montreal Protocol for the elimination of chlorofluorocarbons (CFCs). The overall objective of the ACE mission is to improve our understanding of the depletion of the ozone layer, focusing close attention to what is happening over Canada and the Arctic. The measurements obtained by the ACE-FTS and MAESTRO instruments 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 Government of Canada is working with the international scientific community to determine the extent and causes of atmospheric changes that threaten human health and safety. Sound scientific data is essential to finding effective solutions to problems such as depletion of the ozone layer and climate change. Environment Canada?s studies of the ozone layer, which began over 50 years ago, support a worldwide research and atmospheric monitoring program. And, through the leadership of the Canadian Space Agency, Canada is also involved in research studying the ozone layer from space.
