Abstract
A system to study the evolution of snow density is presented here with an emphasis on the system itself and on the efforts to make a robust system for harsh environments. The metric to deduce the density of the snow is the measurement of the concentration of ambient air oxygen using a tunable diode laser spectroscopy technique: the first harmonic phase angle wavelength modulation spectroscopy. For greater robustness, the system is equipped with an embedded calibration system and is built for a smart power consumption.
