David Griffith's areas of interest and expertise are in solar FTIR remote sensing of atmospheric composition and in the development and application of FTIR spectroscopy for high accuracy in situ trace gas and isotopic fractionation measurements. David did his undergraduate and PhD studies (1975) at Monash University in Australia in chemistry and molecular spectroscopy. He moved into the development of optical techniques for atmospheric trace gas measurements firstly as a visiting scientist at NCAR in Boulder, Colorado (1978-1980), then at the Max Planck Institute for Chemistry in Mainz, Germany (1980-1986). Since 1986 he has been at the Dept. of Chemistry, University of Wollongong and leads the university's Centre for Atmospheric Chemistry. His work has focused on Fourier Transform Infrared (FTIR) spectroscopy for both solar remote sensing and in situ measurements of trace gases. Remote sensing measurements are part of the Network for Detection of Atmospheric Composition Change (NDACC, formerly NDSC) and more recently the Total Carbon Column Observing Network (TCCON), operating high resolution ground based FTIR observatories in Darwin and Wollongong, Australia. In situ FTIR trace gas measurements are combined with micrometeorological techniques to measure the fluxes and exchanges of trace gases at the earth's surface from agriculture, biomass burning and natural ecosystems. Real time field measurements of isotopic composition of CO₂ and water vapour are a current focus of this work.
