The design and experimental characterization of a compact CO 2 pulsed Doppler lidar for boundary‐layer meteorology are described. Examples of the predicted and demonstrated performance of the system with respect to signal‐to‐noise ratio and Doppler measurement accuracy are presented. an experimental dataset from the lidar is analysed with different signal processing parameters in order to elucidate the effects of accumulating different numbers of successive lidar pulses and varying the length of the range gate. Typical system parameters are shown to be a range capability of between 3 and 4 km (dependent upon atmospheric conditions) and a velocity accuracy of ≤ 0.5 m s −1 with 112 m range gates.
