For Critical Marine Low Clouds, a Research and Observation Plan
Nov 28, 2016 [ Program News ]       
Marine low clouds hover in the lowest couple of kilometers above the world’s oceans. They produce little but drizzle, and could never match their deeper mid-continent cousin clouds for dramatic weather and severe storms. But marine low clouds are vastly important to the world’s climate and energy balance. They are a major determinant of the [...]

Amazon Study: Rainstorms Carry Particles Needed to Make Clouds
Oct 24, 2016 [ Program News ]       
Understanding how tiny particles emitted by cars and factories affect Earth's climate requires accurate climate modeling. Scientists also need to quantify the effects of these pollutant particles compared to particles naturally present in the atmosphere. One large uncertainty remains: What Earth was like before industrial-era emissions began? In a paper published today in Nature, scientists in [...]

Three Projects Launch New Climate Model Development and Validation Activity
Sep 26, 2016 [ Program News ]       
Research on remote sensing, cloud macrophysics, and clouds-convection representation Within a few years the world of supercomputing will enter the exascale era, putting to work computing systems capable of a billion billion calculations per second. That’s a thousand times faster than the petascale systems that went online only in 2008. This impending technological acceleration means that supercomputer [...]

To Tighten Climate Models, a Livermore Team Investigates the Land-Cloud Interface
Aug 22, 2016 [ Program News ]       
You might say that Yunyan Zhang, a climate scientist at Lawrence Livermore National Laboratory, was born to her work. In her native China, the first syllable of “Yunyan” means “cloud,” and the second “Canadian geese,” the migratory birds that take to the sky in V-shaped formations. In a scientific way, Zhang took to the sky early. [...]

An International Research Consortium Takes Aim at Pan-Arctic Climate Consensus
Aug 22, 2016 [ Program News ]       
Barrow and Oliktok Point, two small places in Alaska, have a big place in understanding the Arctic, a region of the world where climate change has come early and in exaggerated ways. Warming trends there, for instance, are roughly two times the global average. Both of these specks on the Alaska map are home to heavily [...]
