Toronto, Ontario, February 22, 2001 – The Canadian Space Agency (CSA) and
Environment Canada (EC) today unveiled a new scientific instrument that will
be deployed on the CSA’s SCISAT-1 satellite to help scientists increase our
understanding of the depletion of the ozone layer.

EMS Technologies of Ottawa has been awarded a contract worth $2.2 million to
build the MAESTRO instrument (Measurements of Aerosol Extinction in the
Stratosphere and Troposphere Retrieved by Occultation).

AWith today’s announcement we are witness to the power of partnership,
innovation and the development of space-based technologies for the benefit
of humanity. SCISAT-1 and the MAESTRO instrument will help us maintain and
enhance Canada’s expertise in ozone research while helping us better
understand the impact of humanity on our fragile atmosphere” said the
Honourable Brian Tobin, Minister of Industry and Minister responsible for
the Canadian Space Agency. AIt is through cooperation like this between the
Canadian Space Agency, Environment Canada, industry and scientists that we
are advancing space science research to increase our understanding of ozone
depletion, a concern to all Canadians.”

AThis study will focus on the Arctic B one of Canada’s most vulnerable
environments, said Environment Minister David Anderson. AIn recent years,
scientists have observed major changes in the Arctic atmosphere. Climate
change and ozone loss could well have a serious effect on Canada’s far
north. We are already beginning to see the likely effects of climate change:
melting permafrost, and the retreat of permanent icepacks. Despite action
that has been taken to protect the ozone layer, severe depletion is now
occurring in the Arctic during the late winter and early spring. The Arctic
environment is not well understood, and this research will help shed light
on this complex and fragile region.

“As the Member of Parliament for Ottawa West-Nepean,” said Marlene
Catterall, “I am proud of the dedication and contribution of our
high-technology space industries who are committed to innovation. These
companies are working in partnership with the Canadian Space Agency and
Environment Canada and are using their expertise to help scientists find
environmental solutions to safeguard our fragile atmosphere.”

Dr. Gerry Bush, President, EMS Technologies Space & Technology Group
commented that AThe curatorship of our planet is the responsibility of all
those who live on it and EMS is pleased to bring our decades of experience
in the design and development of systems and products for space to bear on
this important space program. Once again, the Government of Canada is
demonstrating global vision and an acute sense of environmental
responsibility and Canadian industry is providing the necessary technologies
to fulfill this mission.

The scientific goal of the SCISAT-1/ACE (Atmospheric Chemistry Experiment)
mission is to measure and understand the chemical processes that control the
distribution of ozone in the Earth’s atmosphere, particularly at high
latitudes. The data, recorded as SCISAT-1 orbits the Earth, will provide
Canadian 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 and
prevent further ozone depletion.

The MAESTRO instrument joins another Canadian instrument, the Fourier
Transform Spectrometer (ACE-FTS), designed and built by ABB Bomem of Quebec
City. Both instruments are designed to gather information on the chemical
processes occurring in the ozone layer, approximately 8 km to 50 km above
the Earth’s surface.

Dr. Peter Bernath, Mission Scientist, from the Department of Chemistry at
the University of Waterloo heads a Science Team that includes scientists
from Canada, the United States, Belgium, Japan, France and Sweden. Dr. Tom
McElroy, Environment Canada, is the principal investigator for MAESTRO, with
support from Dr. Jim Drummond of the University of Toronto.
