A Survey of Structure of Atmospheric Turbulence in Atmosphere and Related Turbulent Effects [PDF]

open access: yesAtmosphere, 2021
The Earth’s atmosphere is the living environment in which we live and cannot escape. Atmospheric turbulence is a typical random inhomogeneous medium, which causes random fluctuations of both the amplitude and phase of optical wave propagating through it.

A new reference-quality precipitation gauge wind shield [PDF]

open access: yesAtmospheric Measurement Techniques, 2023
Gauge-based precipitation measurements suffer from undercatch due to the effects of wind, with solid-precipitation measurements especially susceptible to such errors.

The quantification and correction of wind-induced precipitation measurement errors [PDF]

open access: yesHydrology and Earth System Sciences, 2017
Hydrologic measurements are important for both the short- and long-term management of water resources. Of the terms in the hydrologic budget, precipitation is typically the most important input; however, measurements of precipitation are subject to large

Intercomparison of In Situ Sensors for Ground-Based Land Surface Temperature Measurements

open access: yesSensors, 2020
Land surface temperature (LST) is a key variable in the determination of land surface energy exchange processes from local to global scales. Accurate ground measurements of LST are necessary for a number of applications including validation of satellite ...

Laboratory Measurements of the Influence of Turbulence Intensity on the Instantaneous-Fading Reciprocity of Bidirectional Atmospheric Laser Propagation Link

open access: yesApplied Sciences, 2021
The reciprocity of the atmospheric turbulence channel in the bidirectional atmospheric laser propagation link is experimentally tested. The bidirectional transceiving coaxial atmospheric laser propagation link is built by using a hot air convection-type ...

Beam Properties of a Partially Coherent Beam Propagating Horizontally in Atmospheric Turbulence

open access: yesPhotonics, 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.

Atmospheric turbulence forecasting using two-stage variational mode decomposition and autoregression towards free-space optical data-transmission link

open access: yesFrontiers in Physics, 2022
Free space optical communication (FSOC) is a promising technology for satellite-to-earth communication systems, where vector beams, especially orbital angular momentum (OAM), can further increase the capacity of the optical link.

Evaluating time domain reflectometry and coaxial impedance sensors for soil observations by the U.S. Climate Reference Network

open access: yesVadose Zone Journal, 2020
The objective of this study was to evaluate the performance of two commercial‐grade electromagnetic sensors in measuring soil water content for the U.S. Climate Reference Network (USCRN). One sensor was a 50‐MHz coaxial impedance dielectric sensor (model
