In collaboration with NASA Scientist, Emily Wilson, MACH 33 Engineering received the Technology Transfer License to continue developing and manufacturing an instrument which measures CO2 and Methane in Earth’s atmosphere.
Laser heterodyne radiometry is a technique based on the radio receiver that has been in use since the 1970s for monitoring the concentrations of trace gases in the atmosphere. At GSFC, we have been developing passive, low-cost miniaturized versions of this technique since 2006 for both ground instruments and CubeSats using distributive feedback (DFB) lasers.
