    Dr. Pickering is an atmospheric scientist employed by NASA Goddard Space Flight Center and works in the Atmospheric Chemistry and Dynamics Laboratory of the Earth Sciences Division, where he is involved in many atmospheric chemistry modeling and analysis activities.  Dr. Pickering conducts air quality applications using data from the Ozone Monitoring Instrument (OMI) onboard NASA’s Aura satellite, and directs regional air quality modeling simulations using CMAQ and WRF-Chem.  He served as Co-Chair of the Air Quality Working Group for the Aura Science Team and has directed projects sponsored by NASA’s Applied Sciences Air Quality Program.  Dr. Pickering is also Project Scientist for the NASA Earth Venture - 1 DISCOVER-AQ (Deriving Information on Surface Conditions from Column and Vertically-Resolved Observations Relevant to Air Quality) project under which  major field experiments have been conducted in the Baltimore-Washington area, the San Joaquin Valley, Houston, and the Front Range region of Colordo from 2011 to 2014.  He leads other projects aimed at evaluating convective transport in NASA’s global chemical transport model (GMI) and chemistry and climate model (GEOS-5 CCM).  Dr. Pickering is an Adjunct Professor in the Department of Atmospheric and Oceanic Science Department (AOSC) at the University of Maryland where he advises graduate student research and collaborates with other faculty members.

     From 1994 to 2005, Dr. Pickering was a research faculty member in AOSC at the University of Maryland, where he conducted model development and applications on scales ranging from individual convective clouds to regional and global domains.   Cloud-resolved model simulations conducted by Dr. Pickering examined convective transport of trace gases and production of NOx by lightning.  On larger scales, Dr. Pickering directed research to evaluate the magnitude of continental outflow of pollution from North America.  From 1988 to 1994, Dr. Pickering worked for research organizations on-site at NASA Goddard Space Flight Center.  From 1976 to 1984, he performed air quality modeling for GEOMET, Inc. in Rockville, MD.

     Dr. Pickering received his Ph. D. in Meteorology from the University of Maryland in 1987, a MS in Atmospheric Science from the State University of New York at Albany in 1975 and a BS in Meteorology from Rutgers University in 1973.

    Brief Bio

    Dr. Pickering is an atmospheric scientist employed by NASA Goddard Space Flight Center and works in the Atmospheric Chemistry and Dynamics Laboratory of the Earth Sciences Division, where he is involved in many atmospheric chemistry modeling and analysis activities.  Dr. Pickering conducts air quality applications using data from the Ozone Monitoring Instrument (OMI) onboard NASA’s Aura satellite, and directs regional air quality modeling simulations using CMAQ and WRF-Chem.  He served as Co-Chair of the Air Quality Working Group for the Aura Science Team and has directed projects sponsored by NASA’s Applied Sciences Air Quality Program.  Dr. Pickering is also Project Scientist for the NASA Earth Venture - 1 DISCOVER-AQ (Deriving Information on Surface Conditions from Column and Vertically-Resolved Observations Relevant to Air Quality) project under which  major field experiments have been conducted in the Baltimore-Washington area, the San Joaquin Valley, Houston, and the Front Range region of Colordo from 2011 to 2014.  He leads other projects aimed at evaluating convective transport in NASA’s global chemical transport model (GMI) and chemistry and climate model (GEOS-5 CCM).  Dr. Pickering is an Adjunct Professor in the Department of Atmospheric and Oceanic Science Department (AOSC) at the University of Maryland where he advises graduate student research and collaborates with other faculty members.

     From 1994 to 2005, Dr. Pickering was a research faculty member in AOSC at the University of Maryland, where he conducted model development and applications on scales ranging from individual convective clouds to regional and global domains.   Cloud-resolved model simulations conducted by Dr. Pickering examined convective transport of trace gases and production of NOx by lightning.  On larger scales, Dr. Pickering directed research to evaluate the magnitude of continental outflow of pollution from North America.  From 1988 to 1994, Dr. Pickering worked for research organizations on-site at NASA Goddard Space Flight Center.  From 1976 to 1984, he performed air quality modeling for GEOMET, Inc. in Rockville, MD.

     Dr. Pickering received his Ph. D. in Meteorology from the University of Maryland in 1987, a MS in Atmospheric Science from the State University of New York at Albany in 1975 and a BS in Meteorology from Rutgers University in 1973.
