- Deep convection and its effect on tropospheric chemistry
- Evaluation of parameterizations of deep convective transport in
mesoscale and global models
- Production and redistribution of NOx from lightning in convective clouds
- Photochemical modeling of ozone production
- Air quality applications of satellite observations
Dr. Pickering's research interests are focused on atmospheric chemistry
and the meteorology of atmospheric transport of trace gas species. Dr.
Pickering's work has centered on simulation of vertical transport of
trace gases by deep convective clouds and calculation of the subsequent
perturbations to photochemical ozone production in the troposphere. For
example, he worked on simulations of convection and chemical tracer
transport over Brazil during the NASA TRACE-A (Transport and Atmospheric
Chemistry Near the Equator - Atlantic) experiment, which was conducted during
the Southern Hemisphere biomass burning season. Dr. Pickering is the PI of
a NASA project to evaluate convective transport in a global chemical transport
model and a chemistry/climate model using cloud-resolving model simulations for
observed convective events. Dr. Pickering has led several efforts to better
constrain the amount of production of NOx by lightning. These efforts have
employed cloud-resolving model simulations using observed lightning flash rates
and use of NO2 observations from the OMI instrument on NASA's Aura satellite.
He has led the implementation of lightning NOx production algorithms for NASA's
Global Modeling Initiative (GMI) chemical transport model and for EPA's
Community Multiscale Air Quality (CMAQ) model. He is also using OMI data in
assessing tropospheric NO2 trends relative to changing NOx emissions over the
Eastern and Central US. Dr. Pickering has participated as part of the theory
and flight planning teams for many NASA and NSF atmospheric chemistry field
Dr. Pickering received his Ph.D. in Meteorology from the University of Maryland
in 1987. Prior to his Ph.D. studies, he was employed by a private consulting
company in the field of air pollution meteorology. He received his M.S. degree
in Atmospheric Science from the State University of New York at Albany in 1975
and his B.S. from Rutgers University in 1973. Dr. Pickering was the recipient
of the NASA Atmospheric Chemistry and Dynamics Branch Contractor Award for
Scientific Achievement in 1992, the Universities Space Research Association
Scientific Excellence Award in 1993, and the University of Maryland Department
of Meteorology Distinguished Alumnus Award in 2003. He is a member of the American
Meteorological Society, the American Geophysical Union, and the Air and
Waste Management Association.
