Results: When it comes to understanding
how atmospheric particles affect climate, one measurement can't tell the whole story, especially in areas that haven't been studied.
Studying clouds and aerosols won't just help scientists study the climate, it's also a chance to investigate air quality and
how atmospheric particles affect daily life.

They plan to examine data from other instruments on MAVEN to see if escaping
particles map to the same regions where they see reconnected magnetic fields to confirm that reconnection is contributing to Martian
atmospheric loss and determine
how significant it is.
«If we know
how volcanic sulfur
particles affect the
atmospheric winds, we can have a much improved interpretation of the traces of volcanic activities in the ice cores,» says Dr. Toohey.
And by carefully measuring and modeling the resulting changes in
atmospheric composition, scientists could improve their estimate of
how sensitive Earth's climate is to CO2, said lead author Joyce Penner, a professor of
atmospheric science at the University of Michigan whose work focuses on improving global climate models and their ability to model the interplay between clouds and aerosol
particles.

how the sun's cycles of activity and Earth's
atmospheric particles influence our climate is unclear, but NASA's Glory mission should provide some answers

atmospheric researcher Dr. Susannah Burrows and collaborator Daniel McCoy, who studies clouds and climate at the University of Washington, reveal
how tiny natural
particles given off by marine organisms — airborne droplets and solid
particles called aerosols — nearly double cloud droplet numbers in the summer, which boosts the amount of sunlight reflected back to space.

atmospheric particles such as soot, and
how they travel around the globe and end up in the Arctic.
This approach, described in a recent article in the journal Geoscientific Model Development, improves the way models represent
atmospheric particles, clouds, and
particle - cloud interactions and
how they vary at regional and local scales.
They will focus on simulations that explore
how the scale of the model affects clouds and
atmospheric particles in different climate regimes.
