Cloud Condensation Nuclei


GCMD >> EARTH SCIENCE >> Atmosphere >> Aerosols >> Cloud Condensation Nuclei
Movie ID Title
This segment provides an introduction to aerosols- their varied sources, brief lifetimes, and erratic behavior. Glory’s APS will help researchers determine the global distribution of aerosol particles. This unique instrument will unravel the microphysical properties of aerosols, and will shed light on the chemical composition of natural and anthropogenic aerosols and clouds. 10525 Hello Crud
Microscope video of tractor soot. Video courtesy of Chere Petty, University of Maryland, Baltimore County; NSF grant DBI-0722569. 10393 Soot and Sulfate Still Images and Video of Tractor Soot Particle
Microscope video of potassium particles. 10391 Potassium Aerosols
Microscope video of sea salt. 10390 Sea Salt Aerosols
Forest fires (biomass burning) emit black soot carbon aerosol clouds. Sun rays are absorbed by these dark clouds. Some sun rays are reflected and some still travel through the cloud to the ground. 10389 Aerosols Absorb; Aerosols Reflect
This animation shows how a cloud is formed on the particle-level. Water droplets and black soot carbon aerosols mix in the air. Water droplets cling to aerosol particles, creating a larger water droplet. The droplet becomes very large and 'pops' into smaller water droplets, each with an aerosol particle inside, thus creating a cloud. 10387 Aerosols Impact Cloud Formation
This animation illustrates how dust particles with ice crystals form mesospheric clouds. 10154 AIM's Cosmic Dust Experiment and Cloud Formation
