An ASR project combines field measurements, lab experiments, and computer modeling
Aerosols are tiny particles suspended in the atmosphere. Many of these particles form from vapors in a process called new particle formation (NPF). If these new particles grow from their initial size of around 1 nanometer (nm) in diameter to over 50 nm, they may [...]

From a farm in India to deep into clouds
Some of us gaze at clouds. Some investigate them.
Virendra Prakash Ghate, an atmospheric scientist at Argonne National Laboratory in Illinois, investigates the microphysics of low clouds, atmospheric radiation, and vertical velocity (mainly updrafts) within the atmosphere.
With clouds as a focus, his job, supported in part by Atmospheric [...]

A GoAmazon study examines the aerosol-making potential within deep canopy cover
One day during the spring of 2014, Pennsylvania State University atmospheric scientist Jose D. Fuentes stood on top of a 50-meter rainforest observation tower near Manaus, Brazil.
“Suddenly,” he said, “this magnificent and colorful bird came from nowhere.” Then a troop of monkeys skittered through the [...]

Beginning in 2017, the Atmospheric System Research (ASR) program is re-organizing from three working groups into four new groups. The focus remains on key cloud, aerosol, precipitation, dynamic, thermodynamic, and radiative transfer processes that have the potential to improve the accuracy of regional and global climate models. The goal of the re-organization is to make [...]

At the 2016 American Geophysical Union Fall Meeting in San Francisco, December 12 to 16, nearly 24,000 scientists from around the world are gathering to share their latest research results in all areas of Earth science. Connect with Atmospheric System Research scientists by attending their session or visit their poster.
Below are a few items [...]

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 [...]

Robert McGraw, Atmospheric System Research (ASR) researcher, has been recognized with an Aerosol Science and Technology (AS&T) Outstanding Publication Award from the American Association for Aerosol Research (AAAR) for his 1997 paper: “Description of Aerosol Dynamics by the Quadrature Method of Moments.” Aerosol Science & Technology 27(2): 255-265, doi:10.1080/02786829708965471.
This award, established in 2015, is given [...]

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 [...]

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 [...]

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. [...]

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 [...]
