Acoustics Reveals Short‐Term Air Temperature Fluctuations Near Mars' Surface

Geophysical Research Letters, 2022
Acoustics is new on Mars: it allows the characterization of turbulence at smaller scales than previously possible within the lowest part of the Planetary Boundary Layer.

Atmospheric turbulence prediction: A PCA approach [PDF]

2007 46th IEEE Conference on Decision and Control, 2007
Current and next generation of telescopes resort to adaptive optics in order to compensate for atmospheric turbulence and correct the incident wavefront, which is affected mainly as far as the phase is concerned, in order to get clearer images of the observed objects.

Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection

Advanced Materials Technologies, EarlyView.
A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...

Wave Structure Function and Long-Exposure MTF for Gaussian-Beam Waves Propagating in Anisotropic Maritime Atmospheric Turbulence

Applied Sciences, 2020
The expressions of wave structure function (WSF) and long-exposure modulation transfer function (MTF) for laser beam propagation through non-Kolmogorov turbulence were derived in our previous work. In this paper, based on anisotropic maritime atmospheric

Turbulence transport throughout the heliosphere [PDF]

, 2007
We employ a turbulence transport model to compute distributions of turbulence throughout the heliosphere. The model determines the radial dependence of three (coupled) quantities that characterize interplanetary turbulence, the energy per unit mass, the ...

Magnetic turbulence in a table-top laser-plasma relevant to astrophysical scenarios

Nature Communications, 2017
Understanding the role of magnetic turbulence in the atmosphere is difficult as direct access is limited, but latest laser technology can enable such studies in the lab.

Atmospheric turbulence observed during a fuel-bed-scale low-intensity surface fire [PDF]

Atmospheric Chemistry and Physics
The ambient atmospheric environment affects the growth and spread of wildland fires, whereas heat and moisture released from the fires and the reduction of the surface drag in the burned areas can significantly alter local atmospheric conditions ...
