Joseph T. Hodges (Fed)

Dr. Hodges' research involves the development and application of sensitive and accurate laser-based absorption spectroscopy techniques to measure atmospheric gases and aerosol species. This work has numerous applications, including new gas standards for trace species, reference-quality measurements of greenhouse gases and pollutants in the atmosphere, spectroscopic data used in models of radiative transfer, and the identification of carbon sources based on isotopic composition.
