We
plan a series of research tasks that will relate meteorological
conditions over the TRACE-P domain to the chemical measurements
that will be obtained. Specifically,
we will analyze the in
situ aircraft-derived chemical data as well as imagery from
the MOPITT and MODIS instruments on the recently launched Terra
satellite. To integrate
the chemical data with meteorological processes, we will employ
both diagnostic meteorological data from the national centers
and high resolution numerical meteorological simulations utilizing
the MM5 model. Finally,
Prof. Fuelberg will serve as the DC-8 Mission Meteorologist during
the field portion of the experiment.
Our
overall goal is to characterize the origins and transports of
air masses in which the TRACE-P aircraft will operate, understand
the context of the in situ data with respect to larger scale satellite imagery, and
integrate the chemical data with meteorological conditions using
high resolution modeling. The
research will have four specific components:
- Determine the origins and paths of air parcels encountered
along individual DC-8 and P-3B flight tracks during TRACE-P to understand
the histories of important chemical constituents. Trajectories
will be calculated for this purpose. Results
will be compared with those from climatology,
- Relate flight level chemical measurements to origins of the
air,
- Perform mesoscale numerical simulations to determine the meteorological
processes responsible for patterns of carbon monoxide, aerosols,
ozone, and methane that are observed in imagery from the MOPITT
and MODIS instruments onboard the Terra satellite. The
TRACE-P aircraft data will provide high resolution information
about the image features revealed by Terra (i.e., fine scale
details about vertical and horizontal distributions). This
research will indicate the context of the TRACE-P aircraft-derived
chemical data with respect to the larger scale views provided
by the satellite
- Serve as DC-8 Mission Meteorologist during TRACE-P.
