Resumen
Los aerosoles estratosféricos impactan el brillo del eclipse lunar. La comparación del brillo observado con los modelos teóricos revela que la carga global de aerosoles de El Chichón (1982) coincide con Agung (1963).
Área de la Ciencia:
- Ciencias de la atmósfera ciencia atmosférica.
- La astronomía es la astronomía.
- Volcanología Volcanología.
Sus antecedentes:
- Los eclipses lunares ocurren cuando la Tierra proyecta una sombra sobre la Luna.
- La luz solar se refracta a través de la atmósfera de la Tierra, iluminando la Luna durante un eclipse.
- Los aerosoles estratosféricos influyen significativamente en el brillo observado de la Luna durante los eclipses.
Objetivo del estudio:
- Para cuantificar el impacto de los aerosoles estratosféricos en el brillo del eclipse lunar.
- Para estimar las profundidades ópticas globales de aerosoles utilizando observaciones de eclipses lunares.
- Para comparar la carga de aerosoles de las principales erupciones volcánicas.
Principales métodos:
- Analizó los datos de brillo de 21 eclipses lunares entre 1960 y 1982.
- Comparó el brillo observado con modelos teóricos que asumen una atmósfera libre de aerosoles.
- Profundidades ópticas de aerosol promediadas globalmente calculadas.
Principales resultados:
- Determinó las profundidades ópticas globales de aerosoles a partir de observaciones de eclipses lunares.
- Se encontró que la carga de aerosoles de la erupción de El Chichón de 1982 era comparable a la de la erupción de Agung de 1963.
- Demostró la influencia significativa de los aerosoles volcánicos en la óptica atmosférica.
Conclusiones:
- Los aerosoles estratosféricos de las grandes erupciones volcánicas tienen un impacto global medible y comparable.
- Las observaciones de eclipses lunares proporcionan un método valioso para monitorear la carga global de aerosoles.
- Las erupciones volcánicas como El Chichón y Agung alteran significativamente las propiedades radiactivas atmosféricas de la Tierra.

Atomic Emission Spectroscopy: Interference
In atomic emission spectroscopy (AES), high-temperature atomizers excite a broad range of elements and molecules that generate complex emissions from sources such as oxides, hydroxides, and flame combustion products in the flame or plasma. Several strategies can be employed to minimize spectral interferences caused by overlapping emission lines or bands. These include increasing instrument resolution, choosing alternative emission lines, optimally placing the detector in low-background regions,...
Tidal Forces
The origin of Earth's ocean tides has been a subject of continuous investigation for over 2000 years. However, the work of Newton is considered to be the beginning of the proper understanding of the phenomenon. Ocean tides are the result of gravitational tidal forces. These same tidal forces are present in any astronomical body; they are responsible for the internal heat that creates the volcanic activity on Io, one of Jupiter's moons, and the breakup of stars that get too close to black holes.
Momentum And Radiation Pressure
An object absorbing an electromagnetic wave would experience a force in the direction of propagation of the wave. This force occurs because electromagnetic waves contain and transport momentum. The force accounts for the wave's radiation pressure exerted on the object. Maxwell's prediction was confirmed in 1903 by Nichols and Hull by precisely measuring radiation pressures with a torsion balance. The measuring instrument had mirrors suspended from a fiber kept inside a glass container. Nichols...
The Sulfur Cycle
Sulfur, an important element in the chemical makeup of proteins, is recycled through the atmosphere and aquatic and terrestrial environments. Found in the atmosphere as sulfur dioxide (SO2), sulfur is released by decaying organisms, weathered rocks, geothermal vents, volcanos, and burning fossil fuels. It is deposited into the ecosystem, cycled through the biotic community, and either released back into the atmosphere as gas or deposited in marine sediment for long-term storage and eventual...
Circular Orbits and Critical Velocity for Satellites
The Moon orbits around the Earth. In turn, the Earth (and other planets) orbit the Sun. The space directly above our atmosphere is filled with artificial satellites in orbit. One can examine the circular orbit, the simplest kind of orbit, to understand the relationship between the speed and the period of planets and satellites with respect to their positions and the bodies that they orbit.

Gravity between Spherical Bodies
Newton's law of gravitation describes the gravitational force between any two point masses. However, for extended spherical objects like the Earth, the Moon, and other planets, the law holds with an assumption that masses of spherical objects are concentrated at their respective centers.
This assumption can be proved easily by showing that the expression for gravitational potential energy between a hollow sphere of mass (M) and a point mass (m) is the same as it would be for a pair of extended...
