One thing about cloud scientists: They never have their heads in the clouds. They are as grounded as trees. They hold steady to deep investigations of their subject, those mutable gatherings of water droplets and ice particles that the rest of us might only see as bunnies, lions, and camels.
Take Ann Fridlind, for instance, an [...]

New Lab-funded research findings, models, and feedbacks will inform the global models of the future
Solar radiation pierces through the sky from above. It interacts with clouds, and then with soil, vegetation, and water bodies at the surface of the Earth. Corresponding salvos of heat, water, volatile organic carbon, and aerosols go from Earth to sky. [...]

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 [...]

Postgraduate students from earth and environmental sciences will have an opportunity this summer to explore earth system processes in the Azores archipelago west of Portugal. Members of the Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) field campaign, which starts in June, will contribute to the lesson plan.
ACE-ENA principal investigator Jian Wang and [...]

The shock hasn’t worn off for Pierre Gentine.
Gentine won the Clarence Leroy Meisinger Award, one of several honors handed out during the 97th annual meeting of the American Meteorological Society (AMS) in January in Seattle.
Gentine is an associate professor at Columbia University in New York. He received U.S. Department of Energy Atmospheric System Research (ASR) [...]

The American Meteorological Society (AMS) seeks nominations by May 1, 2017, for its 2018 awards, fellows, and lecturers, and by July 1, 2017, for honorary members.
For most of the 36 AMS awards, nominators—those responsible for uploading and submitting complete nomination packages—must include a nomination letter, the nominee’s curriculum vitae and bibliography, three supporting letters, and [...]

This summer, Atmospheric System Research (ASR) scientists will be well represented at the 38th American Meteorological Society (AMS) Radar Conference in Chicago, Illinois.
Steve Nesbitt, Bobby Jackson, and Pavlos Kollias will assist with short courses during the conference, which will take place August 28 to September 1, 2017, at the Swissotel Chicago.
Kollias, of Stony Brook University, [...]

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 [...]

About 285 Atmospheric System Research (ASR) scientists and Atmospheric Radiation Measurement (ARM) Climate Research Facility staff met March 13 to 16—in the middle of a major snow storm—at the 2017 Joint User Facility/Principal Investigator Meeting in Tysons Corner, Virginia, to review progress from the past year and plan future research directions.
With a reorganized agenda, ASR [...]

The U.S. Department of Energy (DOE) Office of Science Graduate Student Research (SCGSR) Program is accepting new applicants for supplemental funds to conduct part of their thesis research at a DOE laboratory in areas that address scientific challenges central to the Office of Science mission. These research opportunities are expected to advance graduate students' overall doctoral [...]

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 [...]
