An Improved CH₄ Profile Retrieving Method for Ground-Based Differential Absorption Lidar

Atmosphere
Range-resolved CH4 concentration measurement is important prior data for atmospheric physical and chemical models. Ground-based differential absorption lidar (DIAL) can measure the vertical distribution of CH4 concentration in the atmosphere.

Application of geometrical form factor in differential absorption lidar measurement

, 1997
The peak position for a lidar return signal is calculated and measured for the horizontal path with variation of the laser beam divergence angle (theta), and the inclination angle (delta) between the telescope and laser axes.
