• meteor SKiYMET radar at PEARL, Eureka (80N)
• Activity on these 4 themes, fifth theme of
  Climate Change are our
• Vision for the next 5-10 years

Characteristics of, and interactions between, the
global winds and waves (gravity, tidal and
planetary) of the Stratosphere-Mesosphere-Lower
Thermosphere 20-100km

• Radar observations (Equatorial to the Arctic)
  experiments with the Canadian Middle Atmosphere
  (General Circulation) Model (CMAM, with
  interactive chemistry
• This model is also associated with all CSA
  Atmospheric Missions.
• Data-assimilation for CMAM will allow more
  extensive diagnosis of waves and their
  interactions during the next 5 years.

Linkages between stratospheric 20-50km
dynamical systems and planetary waves (PW) and
the dynamics and thermal state of the mesosphere
(50-90km)

• Data assimilation model (U.K. Meteorological
  Office GCM, MetO) (temperatures and winds) from
  0-55km
• Polar Mesospheric Cloud data from Odin-OSIRIS
• Winds from the radars
• CSAs Chinook Mission (launch 2008), global
  stratospheric winds, ozone, temperatures and
  gravity wave fluxes
• Radars will be a synergistic ground-based system

Atmospheric Processes of Climate Change (APOCC)

• Major CSA mission, 10 year Vision for Atmospheric
  Sciences in Canada www.usask.ca.physics.isas
• Professor Manson, as Chair of the Advisory
  Committee provided leadership
• Atmospheric Sciences Team (3 Professors in ISAS)
  will develop one system for a multi-system
  satellite (circa 500M)
• APOCC may include lower atmosphere, tropopause
  region and middle atmosphere processes

12
Atmospheric Processes of Climate
Change (APOCC) contd

• ISAS is involved with development of the School
  of the Environment, and Global Change theme
• We will provide linkages between these two
  entities the new School and APOCC Mission
