Scientists improve detection of Arctic clouds

(Phys.org) —Thin Arctic clouds can no longer hide, thanks to scientists at Pacific Northwest National Laboratory. Atmospheric data gathered by skyward pointing instruments can be "contaminated" by clouds so wispy that they ...

Ice heating up cold clouds

In the Arctic, competition within clouds is hot. The small amount of heat released when water vapor condenses on ice crystals in Arctic clouds, which contain both water and ice, determines the cloud's survival, according ...

New ash studies needed to 'limit air traffic chaos'

Better research models of how ash is dispersed would greatly reduce the air traffic havoc wreaked in Europe since an Icelandic volcano began spewing a giant cloud of the toxic dust last week, an expert said on Sunday.

Strong ozone depletion above the arctic possible

This winter, the Arctic stratosphere so far has been unusually cold. Hence, all prerequisites are given for strong ozone depletion in the next weeks. This conclusion is based on first results of the POLSTRACC measurement ...

Declining sea ice to lead to cloudier Arctic: study

Arctic sea ice has been declining over the past several decades as global climate has warmed. In fact, sea ice has declined more quickly than many models predicted, indicating that climate models may not be correctly representing ...
