Beginning in 2012, our group has partnered in the development of Laser Heterodyne Radiometry (LHR) , a passive technique for measuring concentrations of gasses in the atmospheric column. Our initial work was done in collaboration with Emily Wilson, a group alumni, in her role at NASA's Goddard Space Flight Center.
Since 2018, we have worked with David Bomse, President of Mesa Photonics in Santa Fe, New Mexico on a variant of LHR known as Precision Heterodyne, Calibrated Spectroscopy (PHOCS). Mesa Photonics and our lab are currently funded by the Department of Energy in a project aimed at measuring the Vertical Profile of water vapor in the atmosphere. (see a news article and a technical paper describing this effort).
