Echo-Signal De-Noising of CO<sub>2</sub>-DIAL Based on the Ensemble Empirical Mode Decomposition

Echo-Signal De-Noising of CO<sub>2</sub>-DIAL Based on the Ensemble Empirical Mode Decomposition

The carbon dioxide (CO<sub>2</sub>) differential absorption lidar echo signal is susceptible to noise and must satisfy the high demand for signal-retrieval precision. Thus, a proper de-noising method should be selected to improve the inversion result. In this paper, we simultaneously dec...
