Specifically, our studies are in four areas:
- Reprocess the HALOE data set using a suite of improved
algorithms that extend or enhance H2O and O3 measurements
well into the upper troposphere.
- Conduct detailed data validation studies of this reprocessed
data.
- Construct climatologies of upper-troposphere O3 and
H2O to garner information on transport and climate, polar
ozone lost climatology and climatologies of HCl and HF.
- Study long-term changes and variability using these
new data products.
The existing 14 years of HALOE data uniquely allow examination
of both temporal and zonal averages of upper-troposphere/lower-stratosphere
O3 and H2O; furthermore, the data set allow studies
of variability in these two regions due to natural and anthropogenic
forcing. The HALOE V20 data product aids in an expanded
understanding of trace gas transport, chemistry, and associated
coupling in the lower stratosphere and upper troposphere.
It provides essential information for assessing the
role of anthropogenic versus natural processes in global
climate change.
