Tropospheric ozone (O3) is one of the important greenhouse
gases. This fact was a common knowledge in the research field
of atmospheric radiation, but it has been ... recently re-focused in
the atmospheric environmental science. Atmospheric ozone also
plays an important role in controlling a number of reactions.
For example, photolysis of ozone by ultraviolet radiation leads
to the production of OH, which scavenges many important trace
gases including CH4, HCFCs and CO.
Tropical Asia, in particular Indonesian maritime continent and
northern Australia, is the region where trace gas distributions
in the troposphere is strongly influenced by deep convection,
frequent lightning and biomass burning. Quantitative studies of
these processes have been very limited so far in this region
because of the lack of simultaneous measurements of key species.
The BIBLE activities is comprised of in situ observations aboard
an aircraft supplemented with simultaneous satellite
observations and numerical modeling efforts. Ground-based
measurements are also encouraged for trace gases in this region.
BIBLE aims at investigating the impact of biomass burning on
tropospheric chemistry in the dry season in tropical Asia.
Major scientific issues to be studied by BIBLE are:
- Estimation of the amounts of trace gases and aerosols emitted
by biomass burning. This requires aircraft measurements in the
boundary layer near a burning area. The measurement data will
be extrapolated to estimate the regional amounts of trace gas
production with the aid of the data for burning areas obtained
from satellite infrared imaging such as AVHRR aboard the NOAA
- Vertical transport processes of biomass burning plumes. It is
anticipaged that high convective activity is associated with
biomass burning over Indonesia, leading to an efficient
transport of biomass burning plumes from the boundary layer to
the free troposphere.
- Long-range transport and chemical transformation of the
biomass burning plumes.
- Impact of production of ozone precursor gases on ozone photochemistry
- Lighting as a source of reactive nitrogen
- Statistical study of the NOx production
- NO production by a thoudercloud
- Convective transport of trace gases
