Research Experience
Current work uses infrared solar absorption spectroscopy from ground-based and airborne Fourier transform interferometers to determine abundances of terrestial atmospheric gases. Includes building instrumentation, making observations, data acquisition and analysis code development and data analysis.
Participated in field programs both ground-based and aboard NASA and NCAR aircraft (since 1991: AASE2, SLATT, SESAME, ACCENT, TOPSE, SOLVE, MIRAGE, PAVE). Measured spectra have resulted in studies of latitudinal and seasonal distributions of important constituents (eg. HCl, HDO, H2O, HF, HNO3, ClONO2) and measurements have also been included in numerous satellite validation efforts.
Lead in building, deploying and maintaining a ground-based FTIR system in Thule, Greenland and re-establishment of the system at MLO HI as part of the international NDACC program. These provide data on long-term trends of greenhouse gases and their effects on climate change and polar O3 chemistry. Is a significant component in satellite validation programs for HIRDLS, MLS, ACE, MIPAS and SCIAMACHY.
2005 elected co-Chair of the Infrared Working Group of the NDACC, re-elected in 2008, 2011, Member of the NDACC Steering Committee. Member SPARC/IGACO/IOC O3 profile Assessment Committee.
