Beam Properties of a Partially Coherent Beam Propagating Horizontally in Atmospheric Turbulence
Photonics, 2023 This study explored the impact of atmospheric turbulence on partially coherent light propagation. Atmospheric turbulence causes random modulation of the intensity and phase of light, resulting in a speckle pattern in the far field.

Propagation Properties of an Astigmatic Cos-Gaussian Beam through Turbulent Atmosphere [PDF]
E3S Web of Conferences, 2021 We use the extended Huygens-Fresnel integral to investigate the propagation properties of a cos-Gaussian beam (cosGB) with astigmatism in atmospheric turbulence.

Ergodicity test of the eddy-covariance technique [PDF]
Atmospheric Chemistry and Physics, 2015 The ergodic hypothesis is a basic hypothesis typically invoked in atmospheric surface layer (ASL) experiments. The ergodic theorem of stationary random processes is introduced to analyse and verify the ergodicity of atmospheric turbulence measured using ...

Testing and development of transfer functions for weighing precipitation gauges in WMO-SPICE [PDF]
Hydrology and Earth System Sciences, 2018 Weighing precipitation gauges are used widely for the measurement of all forms of precipitation, and are typically more accurate than tipping-bucket precipitation gauges.
