Tellus: Series B, Chemical and Physical Meteorology, 2019 Dry deposition is an important loss process for atmospheric particles and can be a significant part of total deposition estimates calculated for critical loads analyses. However, algorithms used in large-scale air quality and atmospheric chemistry models

A lidar for detecting atmospheric turbulence based on modified Von Karman turbulence power spectrum
Frontiers in PhysicsIntroduction: Atmospheric turbulence is a kind of random vortex motion. A series of turbulent effects, such as fluctuation of light intensity, occur when laser is transmitted in atmospheric turbulence.Methods: In order to verify the possibility of ...

Rethinking Atmospheric Turbulence Mitigation
CoRR, 2019 State-of-the-art atmospheric turbulence image restoration methods utilize standard image processing tools such as optical flow, lucky region and blind deconvolution to restore the images. While promising results have been reported over the past decade, many of the methods are agnostic to the physical model that generates the distortion.
