Biographical Sketch

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 campaigns.

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.
