Methods of Obtaining Topography01:25

Methods of Obtaining Topography

Topography involves measuring and mapping land elevations, natural features, and artificial structures to create accurate representations of the terrain. Topographic surveying relies on traditional and modern methods, each with distinct advantages and limitations.Traditional Surveying Methods:Transit stadia surveys and plane table surveys were widely used traditional surveying methods. These techniques relied on instruments like theodolites and stadia rods for measuring distances and angles,...
Precipitation Gravimetry01:03

Precipitation Gravimetry

Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

Influence of Earth's Curvature and Atmospheric Refraction on Leveling

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. Over a...
Application of Linearization and Approximation01:29

Application of Linearization and Approximation

A drone flying through complex terrain often relies on more than one sensing method to estimate small changes in altitude. Along with direct measurements, air pressure provides a useful indirect indicator of vertical movement. Atmospheric pressure decreases as altitude increases, and this relationship is commonly described using an exponential model. Although accurate, converting pressure measurements into altitude values requires calculations that are too complex to perform repeatedly during...
Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview01:13

Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview

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.
The ATR process begins by directing a beam...
Variation of Atmospheric Pressure01:18

Variation of Atmospheric Pressure

Change in atmospheric pressure with height is particularly interesting. The decrease in atmospheric pressure with increasing altitude is due to the decreasing gravitational force per unit area as we move away from the surface of the earth.
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
Let p(y) be the atmospheric pressure at...

    Summary

    The effective instrument function method for atmospheric remote sensing is affected by atmospheric deviations. An alternative circulation method, though computationally intensive, bypasses the need for prior atmospheric data.

    Area of Science:

    • Atmospheric Science
    • Remote Sensing
    • Geophysics

    Background:

    • Atmospheric remote sensing relies on accurate atmospheric models for inversion.
    • Deviations between reference and actual atmospheric conditions can impact inversion accuracy.
    • The effective instrument function method is a common technique for atmospheric remote sensing.

    Purpose of the Study:

    • To analyze the impact of atmospheric deviations on the effective instrument function method.
    • To introduce and evaluate an alternative method, the circulation method, for atmospheric remote sensing inversion.

    Main Methods:

    • Developed the circulation method based on the effective instrument function method.
    • Assessed the computational time and data requirements of both methods.

    Main Results:

    • The effective instrument function method's accuracy is sensitive to atmospheric deviations.
    • The circulation method provides an alternative approach to atmospheric remote sensing inversion.
    • The circulation method requires more computation time than the effective instrument function method.

    Conclusions:

    • The circulation method is a viable alternative for atmospheric remote sensing when a priori atmospheric profile information is unavailable.
    • Understanding the influence of atmospheric deviations is crucial for accurate remote sensing data interpretation.
