Analysis of atmospheric turbulence dynamics during the total solar eclipse with AI-based sensing
Summary
Atmospheric optical turbulence dynamics were studied during a total solar eclipse (TSE). Dual turbulence quiescent phases and quasi-periodic oscillations were observed, offering new insights into atmospheric phenomena.
Area of Science:
- Atmospheric physics
- Optical turbulence research
Background:
- Atmospheric optical turbulence affects light propagation.
- Total solar eclipses (TSE) cause unique atmospheric conditions.
Purpose of the Study:
- Investigate atmospheric optical turbulence dynamics during the 2024 TSE.
- Analyze changes in refractive index structure parameter (Cn2).
Main Methods:
- Experimental analysis using a laser beam over a 7 km path.
- Measurements of Cn2 with a large-aperture scintillometer.
- High-temporal-resolution Cn2 evaluation using the AI-based TurbNet sensor.
Main Results:
- Observed dual turbulence quiescent (neutral stratification) phases.
- Detected quasi-periodic oscillatory patterns in Cn2 during and after totality.
- Characterized Cn2 parameter time evolution throughout the TSE event.
Conclusions:
- The 2024 TSE significantly influenced atmospheric optical turbulence.
- Dual quiescent phases and oscillatory patterns provide new data on turbulence dynamics.
- AI-powered sensors enhance the study of rapid atmospheric changes.

Influence of Earth's Curvature and Atmospheric Refraction on Leveling
272
During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance.

Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview
555
Attenuated total reflectance (ATR) infrared spectroscopy is a powerful analytical technique used to study the composition of materials. It is widely employed in chemistry, materials science, forensic science, and other fields where sample characterization is required. ATR has several advantages over traditional transmission IR spectroscopy, including the requirement of little to no sample preparation and the ability to analyze a wide range of samples.

Relative Motion Analysis using Rotating Axes
533
Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it...

Turbulent Flow
277
Turbulent flow is characterized by unpredictable fluctuations in velocity and pressure, which result in a chaotic fluid movement distinct from the orderly patterns of laminar flow. While laminar flow is governed by smooth, parallel layers with minimal mixing, turbulent flow exhibits highly irregular, three-dimensional patterns. This behavior arises due to instabilities in the fluid's velocity profile, and amplifies as the flow velocity increases. Minor disturbances, known as turbulent...

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation
296
Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used....

Turbulent Flow: Problem Solving
185
Carbonation is a process used to dissolve carbon dioxide gas in a liquid, commonly used in the production of carbonated beverages. Achieving efficient carbonation requires careful control of temperature, pressure, and flow conditions. By adjusting these parameters, carbonation efficiency can be maximized, producing a higher concentration of CO2 in the liquid.
Temperature is a key factor in CO2 solubility. In this case, the CO2 gas and the liquid are cooled to 20°C. Lower temperatures...
