Dr. Burkholder is a research chemist in NOAA's Earth System Research Laboratory in Boulder, Colorado, USA. His primary research interest involves laboratory studies and instrument development to elucidate the role of chemical processes in Earth's atmosphere and their impact on society. Research studies involve a broad range of topics related to stratospheric ozone depletion, regional and global air quality, and climate change. Areas of current research include (1) Measurement and interpretation of the photochemistry (absorption cross sections and photolysis quantum yields) of key atmospheric trace species involved in polar ozone destruction and production of HOx, halogen oxides, and NOx radical species, (2) Evaluation of chlorofluorocarbon (CFC) and Halon replacement compounds and assessment of their ozone depletion (ODP) and global warming potentials (GWP), (3) Kinetic studies and model interpretation of new particle formation (nucleation) from biogenic compounds, (4) Evaluation of biogenic and anthropogenic compound oxidation mechanisms that impact regional air quality via laboratory measurements of their reactivity, product formation and reaction mechanisms. Additional information on our research is available from the links to laboratory studies and ACCP group activities.
