Daniel McKenna was educated at the University of Glasgow, Scotland where he earned a 1st Class Honours degree in Chemical Physics with Advanced Mathematics in 1980. He was awarded his Ph.D. in Theoretical Chemistry in 1983 from the same institute, completing the experimental component at the University of Zürich and the Swiss Institute for Nuclear Physics. His Ph.D. thesis described quantum mechanical calculations and magnetic resonance measurements of elementary particles that explored isotopic mass effects in small molecules. McKenna began his training in atmospheric science in 1983 when he completed the Scientific Officers Training course in Meteorology on joining the United Kingdom Meteorological Office. McKenna worked for several years at the UK Met Office in the Atmospheric Chemistry Group and assumed leadership of the group in 1990. During his time at the Met Office, McKenna participated in and had leadership roles in UK, European and US field campaigns, including in 1987 and 1989 the NASA led airborne polar campaigns that first investigated the destruction of the ozone layer, and the 1991 Met Office campaign to the Persian Gulf at the end of the first Gulf War that made the earliest estimates of the magnitude and environmental impacts of the pollution from the oil well fires. In 1994, McKenna moved to the Forschungszentrum Juelich (FZJ) in Germany as the founding director of the Institute for Stratospheric Chemistry (ICG1) and as Adjunct Professor in the Department of Physical Chemistry of the University of Bonn. As ICG1 director, McKenna developed an integrated program of instrument and model development, field deployments and model analysis and as adjunct professor taught courses in atmospheric physics and chemistry at the University of Bonn and supervised 8 doctorial and two diploma students. During his tenure at FZJ he served as a program coordinator for the Ozone Research Program (OFP) of the German Federal Ministry for Education and Research (BMBF) with particular responsibilities for ‘Prognostic Capabilities’, and served on the International Ozone Commission (IO3C). At the beginning of 2001, McKenna moved to the National Center for Atmospheric Research (NCAR) as Director of the Atmospheric Chemistry Division (ACD). During his tenure as ACD director, McKenna was instrumental in the development of the Megacity Impact on the Regional and Global Environment (MIRAGE) and in the Upper Troposphere and Lower Stratosphere (UTLS) programs. He also oversaw the design and building of a new custom facility for the Atmospheric Chemistry Division, occupied in 2005, on time and on budget. In 2010, McKenna moved to Oak Ridge National Laboratory as Computational Earth Sciences Group Leader and a member of the Climate Change Science Institute. Throughout his career McKenna has served as a proposal and program coordinator and has extensive experience as an expert reviewer of grant proposals, scientific assessments and journal articles. McKenna’s scientific interests are related to stratospheric ozone depletion, tropospheric pollution and meteorology-chemistry interactions. He has been a pioneer in the application of Lagrangian techniques to scientific problems related to the stratosphere and troposphere. He led the development of the Chemical Lagrangian Model of the Stratosphere (CLaMS), a novel application of the Lagrangian approach beyond isolated air parcels. Simulations made with this model have contributed unique insights into stratospheric chemistry and transport processes. McKenna has performed studies on the formation of mini-hole formation in Polar Regions, impacts of denitrification on ozone destructions rates, relative contributions of catalytic cycles to ozone loss, empirical and model estimates of ozone destruction, long-range pollution transport and pollutant dispersion and removal rates. At ORNL he is building upon his interest in sub grid scale variability and mixing by developing a research program in Stochastic Ensemble Modeling. He has published over 50 articles in the peer-reviewed literature.
