In addition, the team found that in clean skies, the heavier ice particles fall faster out of the anvil - shaped clouds, causing the clouds to dissipate.

Not exact matches

Once those silver iodide particles make their way into a ripe cloud, they collide with drops of supercooled water and form ice; the ice then falls to the ground, melting along the way.

Ginot and his team of researchers can also track aerosols — small particles in the atmosphere that fall with snow and get trapped and stored in the ice, layer by layer, as the years pass.

Smoke from those fires went around the world, but the soot particles falling on ice, especially in Greenland are a big concern.

Geoengineering proposals fall into at least three broad categories: 1) managing atmospheric greenhouse gases (e.g., ocean fertilization and atmospheric carbon capture and sequestration), 2) cooling the Earth by reflecting sunlight (e.g., putting reflective particles into the atmosphere, putting mirrors in space to reflect the sun's energy, increasing surface reflectivity and altering the amount or characteristics of clouds), and 3) moderating specific impacts of global warming (e.g., efforts to limit sea level rise by increasing land storage of water, protecting ice sheets or artificially enhancing mountain glaciers).

Year after year, as fallen snow added layers to the ice sheet, lead emissions were captured along with dust and other airborne particles, and became part of the ice - core record that scientists use today to learn about conditions of the past.
