Description

Rayleigh (R): Specialized Unit for Atmospheric Light Emissions

The rayleigh is a non-SI unit used to measure the faint emissions of light in the upper atmosphere, such as those produced by auroras or airglow. One rayleigh corresponds to 1010 photons per square meter per second along a vertical column. This unit is especially important in geophysics, atmospheric science, and astrophysics for quantifying extremely low levels of light that are invisible to the human eye but detectable by scientific instruments.

Rayleigh measurements are essential for studying natural light phenomena in the Earth's mesosphere and thermosphere. These emissions play a crucial role in understanding the impact of solar activity on Earth, helping scientists monitor space weather and its effects on satellite communications and navigation systems. By quantifying these subtle luminous occurrences, the rayleigh contributes to our broader understanding of planetary atmospheres and cosmic interactions.

Lux Second (lx·s): Unit of Luminous Exposure

The lux second is a unit of luminous exposure that quantifies the cumulative amount of light (illuminance) received by a surface over a specific duration. It is derived by multiplying illuminance, measured in lux, by the time in seconds. This metric is vital in scientific research and industries where both the intensity and duration of light exposure matter, such as photography, photobiology, and lighting engineering.

For photographers and lighting designers, understanding lux seconds helps determine the proper lighting duration for optimal exposure. In biological research, it aids in quantifying light therapy doses or assessing plant light exposure in controlled environments. This unit bridges the gap between instantaneous light measurement and long-term exposure, supporting better accuracy in light-related assessments.
