Study of Particle Size Measurement by the Extinction Method in Flame

Energies, 2023
The laser extinction method (LEM) is particularly suitable for measuring particle sizes in flames because this method, which is based on the Beer–Lambert law, is non-intrusive and easy to implement.

Deriving Snow Depth From ICESat-2 Lidar Multiple Scattering Measurements

Frontiers in Remote Sensing, 2022
Snow is a crucial element in the Earth’s system, but snow depth and mass are very challenging to be measured globally. Here, we provide the theoretical foundation for deriving snow depth directly from space-borne lidar (ICESat-2) snow multiple scattering
