Description

We develop new ultra-sensitive cavity-enhanced spectroscopic methods to address existing measurement needs in atmospheric and climate science. These methods involve laser sources, such as quantum cascade lasers and optical frequency combs to make high accuracy measurements of trace materials and for quantitative measurements of line shape parameters to support remote sensing. Recently, we have been developing an optical cavity ring-down spectrometer to probe radiocarbon dioxide (14CO2) transitions in the mid-infrared spectral region for greenhouse gas and fuel source attribution.
