This highlights the complexity of the interactions between light and atmospheric particles in the formation of these clouds. Another important aspect of NLC research is the role of meteoric dust ...

“You’re looking to the window and you see this ray of light shining inside of your house, you will see all these small particles and dust floating. Well, most of this dust is actually composed ...

He is presently involved in two research areas. (1) The polar ionosphere contains meteoric dust particles that are the nucleation sites for icy cloud particles. Students construct instruments for ...

Wildfire smoke contains small particles that can cause serious health problems. Several parts of Southern California are currently under a windblown dust and ash advisory as deadly wildfires ...

But with the east-to-west wind flow related to the Santa Ana winds, what we're seeing is dust particles rather than smoke. Arizona firefighters deployed to help:California blazes swallow over ...

Earth is "showered in almost 100 tons of meteoric dust each day," the laboratory's website said. It's also bombarded by bits the size of a grain of sand or pebble daily. Larger objects are less ...

At these extreme altitudes, water vapor condenses onto tiny particles — often meteoric dust or volcanic debris — forming minuscule ice crystals, which gives them a radiant glow as they reflect ...
