We present an Optical Parametric Oscillator (OPO)-based differential absorption lidar (DIAL) that operates in the mid-infrared (3.0-4.5 um). Tunability of the OPO is achieved by the use of Potassium Titanyle Arsenate (KTiOAsO4), or KTA crystal. The Dial measurements of methane are in good agreement with reported values and also exhibits diurnal fluctuations in concentration levels during atmospheric monitoring.
