particlesounding

Particlesounding refers to the study and observation of high-altitude ice crystal clouds, specifically the optically bendable nature of the ice crystals within these clouds. This phenomenon occurs when sunlight interacts with the irregularly shaped ice crystals, causing them to refract and bend light in unique ways.

The term "particlesounding" is derived from a combination of the words "particle" and "sounding," which refers to the practice of using radar or other technologies to study the internal structure of clouds. Particlesounding was first described in the 19th century by scientists studying atmospheric ice crystal behavior.

Ice clouds responsible for particlesounding typically occur at altitudes between 15,000 to 25,000 feet (4,570 to 7,620 meters) above the Earth's surface, where the atmosphere is cold enough to support the formation of ice crystals. Within these clouds, the irregularly shaped ice particles interact with sunlight in a complex manner, resulting in characteristics such as halos, glories, and iridescence.

The study of particlesounding has led to a greater understanding of atmospheric science, particularly in the fields of cloud physics and optics. Researchers use various techniques, including instrumented aircraft, satellite imagery, and ground-based radar systems, to collect data on particlesounding. By analyzing this data, scientists can better comprehend the complex processes occurring within these high-altitude clouds, with implications for fields such as weather forecasting and climate research.
