An Atmospheric Turbulence Probe
IEEE Transactions on Geoscience and Remote Sensing, 1980 In this paper, a complete low-cost atmospheric turbulence probe, capable of measuring temperature, differential temperature, humidity, horizontal wind speed and direction, and vertical wind component is described. Special care has been taken to minimize the probe's weight so that it may be carried easily by a balloon.

Blind atmospheric turbulence deconvolution [PDF]
IET Image Processing, 2020 A new blind image deconvolution technique is developed for atmospheric turbulence deblurring to overcome limitations of ‘generic’ blind deconvolution algorithms that do not take into account the complicated physics of the turbulence. The originality of the proposed approach relies on an actual physical model, known as the Fried kernel, that quantifies ...

Free-space optical communication employing subcarrier modulation and spatial diversity in atmospheric turbulence channel [PDF]
, 2008 An expression for the bit error rate of a multiple subcarrier intensity-modulated atmospheric optical communication system employing spatial diversity is derived. Spatial diversity is used to mitigate scintillation caused by atmospheric turbulence, which

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.

Coherent polarization shift keying modulated free space optical links over a Gamma-Gamma turbulence channel [PDF]
, 2011 Problem statement: The optical signal propagating through the Free Space Optical (FSO) channel suffers from irradiance and phase fluctuations caused by the atmospheric turbulence, which results in Bit Error Rate (BER) performance degradation ...
