Having reliable predictions of climate change, such as global warming
and ozone destruction, has become an imperative. With NASA/HPCC funding,
we are participating in a large project with PIs at several other sites
to parallelize and integrate numerical models of atmospheric dynamics
(wind), atmospheric physics (solar heating, precipitation, and other
processes), atmospheric chemistry (ozone production/depletion, as well
as many other chemicals and aerosols), ocean dynamics (currents), and
ocean physics (temperature interaction with the atmosphere). There are
plans to add ocean chemistry as well. Our initial task is to take an
existing atmospheric chemistry model for the Los Angeles Basin, 
scale it up, and parallelize it to handle the whole earth's atmosphere. Eventually a version will be used for the ocean as well.
