Marine bacteria carried by warm and moisture-laden atmospheric rivers contribute to the formation of ice clouds at unexpectedly high temperatures in high-latitude regions, research from Japan suggests ...

With experiments performed in the CLOUD chamber at CERN, researchers aimed to determine whether isoprene oxygenated organic molecules could form new particles under upper-tropospheric conditions.

A new study found tiny microplastics — sized between 7.1 to 94.6 micrometers — in cloud water collected from high-altitude summits in Japan. The researchers suggest that microplastics could therefore ...
