Widespread 'twilight zone' detected around clouds

There is something new under the sun that could complicate scientists' efforts to get a fix on how much the world will warm in the future. In addition to greenhouse gases, clouds, and aerosol particles that influence the temperature of the atmosphere, a new ingredient has been discovered: an extensive and previously unseen "twilight zone" of particles that represents a gradual transition from cloud droplets to dry particles.

1. Drizzly mornings on Xanadu
   10-11-2007 · EurekAlert!
   Noted for its bizarre hydrocarbon lakes and frozen methane clouds, Saturn's largest moon, Titan, also appears to have widespread drizzles of methane. New near-infrared images from ESO's VLT and Keck show for the first time a nearly global cloud cover at high elevations and, dreary as it may seem, a widespread and persistent morning drizzle of methane over the western foothills of Titan's major continent, Xanadu.

3. 'Chinese Lantern' Technique Helps Track Clouds At Saturn
   10-06-2006 · ScienceDaily
   A new image of Saturn demonstrates a technique that creates a 'Chinese lantern' effect, showing Saturn's deep clouds silhouetted against the planet's warm, glowing interior. Seen this way, Saturn's interior shows surprising activity underneath the overlying haze, with a great variety of cloud shapes and sizes.

5. Morning forecast on Titan calls for widespread methane drizzle off Xanadu
   10-11-2007 · EurekAlert!
   New near-infrared images from Hawaii's Keck Observatory and Chile's Very Large Telescope show for the first time a nearly global cloud cover at high elevations on Titan and a widespread and persistent morning drizzle of methane on the flanks of Titan's major continent, Xanadu. UC Berkeley astronomers Imke de Pater and Mate Adamkovics report these observations this week in Science Express and at the AAS's Division for Planetary Sciences meeting.

7. New experiment to investigate the effect of galactic cosmic rays on clouds and climate
   10-23-2006 · EurekAlert!
   A novel experiment, known as CLOUD (Cosmics Leaving OUtdoor Droplets), begins taking its first data today with a prototype detector in a particle beam at CERN , the world's largest laboratory for particle physics. The goal of the experiment is to investigate the possible influence of galactic cosmic rays on Earth's clouds and climate. This represents the first time a high energy physics accelerator has been used for atmospheric and climate science.
