A miniature emph{in-situ} CH$_4$ concentration measurement instrument based upon tunable laser spectroscopy (TLS) was developed and applied in numerous field campaigns. The instrument, a $3.4$ $mu m$ laser spectrometer developed at NASA Jet Propulsion Lab (JPL), is lightweight ($250 g$), low power ($<8$ $W$), and high sensitivity ($10$ $ppb$ $s^{-1}$). The payload was further developed and integrated onto a small UAV at UC Merced, rendering an overall payload weight of $400$ $g$ and real-time data acquisition. The remarkable characteristics of the instrument and prior investigative work regarding sensor placement yielded excellent trial and field results, which are presented in this work.
