Radiation transport modulates the spatial frequencies of atmospheric structures, acting as a low pass filter, which causes the power spectra of the accumulated radiance to have different power spectral slopes than the underlying atmospheric structure. Additional effects arise because of the non-stationarity of the atmosphere. The SHARC atmospheric radiance code is used to model both equilibrium...

Partially coherent beams hold much promise in free-space optical communications for their resistance to the deleterious effects of atmospheric turbulence. We describe the basic theoretical and computational tools used to investigate these effects, and review the research to date.

Free space optical (FSO) communication has been receiving increasing attention in recent years with its ability to achieve ultra-high data rates over unlicensed optical spectrum. A major performance limiting factor in FSO systems is atmospheric turbulence which severely degrades the system performance. To address this issue, multiple transmit and/or receive apertures can be employed, and the pe...

• Atmospheric turbulence limits the ability of ground-based telescopes to form images of astronomical or orbiting objects. Turbulence effects also decrease the on-axis intensity otlaser beams propagated from ground to space. Conventional adaptive optics systems typically compensate for the deleterious effects of the atmosphere by sensing the wavefront of light originating at or near the object ...

Abstract This work is devoted to the detection of non-equilibrium turbulence states in atmospheric turbulence. The scaling contradicts classical Richardson-Kolmogorov cascade picture and many models do not account for it. existence such has been discovered various laboratory experiments. We show here that are also present stratocumulus-topped boundary layers, which indicates presence rapidly ch...
