| | The SOLVE II Mission
is an international field campaign designed to acquire correlative data needed
to validate the Meteor-3M/Stratospheric Aerosol and Gas Experiment (SAGE) III
satellite mission. The field campaign will also acquire correlative measurements
with atmospheric chemistry instruments onboard the ADEOS-II and ENVISAT satellite
missions to enhance ozone comparison and loss studies utilizing these data sets.
Measurements will be made during the Arctic winter using the NASA DC-8 aircraft,
balloon platforms, and ground-based instruments. These activities will take
place in close collaboration with the European Validation of International Satellites
and Study of Ozone Loss (VINTERSOL) campaign, which will include flights of the
DLR Falcon and Russian Geophysica M55 aircraft, other balloon platforms and ground-based
instruments. SOLVE-II is co-sponsored by NASA's Upper Atmosphere Research
Program (UARP), Atmospheric Effects of Aviation Project (AEAP), Atmospheric Chemistry
Modeling and Analysis Program (ACMAP), and Earth Observing System (EOS) of NASA's
Earth Science Enterprise (ESE). VINTERSOL is sponsored by the European Commission. Dr.
Michael Kurylo and Dr. Phil DeCola are the SOLVE II Program Scientists. Dr.
Mark Schoeberl and Dr. Paul Newman are the SOLVE II DC-8 Project Scientists, and
Mr. Michael Craig is the SOVLE II Project Manager. SOLVE II has five basic
science objectives. These objectives are: Measurement
of the polar ozone loss rate in early to mid-winter. Relative contributions
to low ozone levels from interannual variations in ozone transport and photochemistry
will be quantified. The understanding of polar stratospheric clouds
(PSC's). The composition of PSC's and the role they play in the interactions
between chlorine and nitrogen reservoir species will be examined. The
study of photochemical processes. The seasonal evolution of chemical processes,
in particular the activation and deactivation of chlorine, and their impact on
ozone loss will be observed. The measurement of polar air transport
and dynamics. The initial state of polar stratospheric air will be defined
and the exchange of this air between the polar vortex and the mid-latitudes will
be observed. This will allow a better understanding of the effect of transport
on the evolution of the ozone. It will also lead to better predictions of
the sensitivity of polar air to jet engine exhaust from current and future aircraft. SAGE
III instrument validation. Ozone, aerosol, water vapor, and NO2
measurements from the DC-8 will be compared to SAGE III instrument measurements
to prove the accuracy of satellite observations.
