Future Principal Investigators Learn About Atmospheric Particles and Their Effects on Earth Systems
Susanne Glienke, a postdoctoral researcher at the Max Planck Institute for Chemistry in Germany, is well acquainted with clouds. During the Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) field campaign, she oversaw an instrument called the Holographic Detector for Clouds (HOLODEC). The device mounts [...]

The annual ARM/ASR joint meeting matched its forecast—a deluge of talks
When more than 300 atmospheric scientists arrived at a conference in Rockville, Maryland, it was raining. Soon, however, the real downpour was indoors.
From June 10 through 13, the 2019 Joint ARM User Facility/Atmospheric System Research (ASR) Principal Investigators Meeting was a deluge of working group [...]

To understand how nucleated particles develop, one scientist will take to the field with an aerosol growth chamber
Officially, atmospheric scientist Donald R. “Don” Collins is a professor of chemical and environmental engineering at the University of California, Riverside.
Such a broad title, however, does not reveal that he grew up near Washington, D.C., drinks his coffee [...]

Scattered across the prairies of north-central Oklahoma and southern Kansas, a collection of 50-plus scientific instruments points to the heavens. This is the Atmospheric Radiation Measurement (ARM) user facility’s Southern Great Plains atmospheric observatory, and those instruments are collecting data on radiation, clouds, aerosols, and other atmospheric processes.
Here, and at ARM observatories and field campaigns [...]

A young scientist presses for improvements in radar retrievals of snowfall properties, cloud microphysics, and more.
In early January 2009, German meteorology undergraduate Maximilian Maahn began a six-month semester abroad at the University Centre in Svalbard, Norway. During the winter months, this mountainous archipelago in the Arctic Ocean—just 650 miles from the North Pole—is pitch-dark 24 [...]

A onetime string theorist now improves the way models represent spectral radiances throughout the atmosphere
Physicist Eli Mlawer (rhymes with “flower”) is a principal scientist at Atmospheric and Environmental Research (AER), a for-profit research company in Lexington, Massachusetts, where he develops algorithms that help modelers represent radiative transfer.
Several times since 2008, Mlawer’s work has been funded [...]

The U.S. Department of Energy (DOE) Office of Science Graduate Student Research (SCGSR) program is now accepting new applicants for supplemental funds to conduct part of their graduate thesis research at a DOE national laboratory/facility in collaboration with a DOE laboratory scientist.
These research opportunities are designed to advance graduate students’ doctoral theses/dissertations while providing access [...]

A highly cited scientist is unraveling the puzzle of mixed-phase clouds and improving how aerosols are represented in earth system models
For good reasons, aerosols are difficult to understand. Unlike other trace gases, which can persist in the atmosphere for years or even centuries, the lifespans of aerosols are measured in days.
To complicate things even more, [...]

Well known for her unique retrievals of cloud properties, a veteran scientist investigates the mystery of secondary ice production
Christine Chiu of Colorado State University investigates clouds. She calls them “complicated 3D objects that evolve fast.”
She studies clouds from below and on all sides with scanning cloud radars and from above with satellite data. Her research [...]

Every year the American Meteorological Society (AMS) presents awards to members of the weather, water, and climate community during its annual meeting. Several scientists recently or currently funded by the Atmospheric System Research (ASR) program received honors during the January 2019 meeting in Phoenix, Arizona.
Christopher Bretherton, a professor of atmospheric sciences and applied mathematics at [...]

Buoyed by a sense of adventure and a passion for clouds, a scientist enters his third decade investigating Earth’s fragile cold regions.
Officially, the U.S. Department of Energy’s (DOE) Atmospheric System Research (ASR) program dates back to 2010. But because of funding cycles already underway back then through administrative predecessors, ASR has an archive of research [...]

A new article in the Bulletin of the American Meteorological Society draws on a wealth of data from a recent Atmospheric Radiation Measurement (ARM) user facility field campaign to demonstrate how land use and soil properties influence temperature and humidity with unexpected strength.
ARM conducted the Holistic Interactions of Shallow Clouds, Aerosols and Land Ecosystems (HI-SCALE) [...]

Ian Williams is among many national laboratory scientists developing new ways to integrate land-atmosphere interactions into climate-predictive models.
Ian N. Williams is a research scientist at the Lawrence Berkeley National Laboratory (LBNL), where he is principal investigator in a program called Land-Atmosphere Coupling and Convection in the Water Cycle.
More broadly, his research involves many threads [...]

Scientists Gather in Argentina to Study the World’s Largest Convective Storms
The Sierras de Córdoba mountain range in north-central Argentina is the birthplace of the largest thunderstorms on Earth. These are the type of storms that contribute most of the rainfall to many regions of the world. Yet to date, a fine-tuned sense of how they [...]

To Improve Models, ASR Researchers Tap Doppler Lidars to Estimate the Critical Cloud-Base Updrafts and Downdrafts that Carry Heat and Moisture
Cumulus clouds, low and rain-free, get their name from the Latin word for “heap.” With flat bases and puffy upper surfaces, such clouds appear to bubble into the sky, turning grey at the bottom and [...]

A newly available principal investigator (PI) product —the Merged Multisensor Cloud-Precipitation Mask and Cloud Type Data for GoAmazon2014/15—can now be used by scientists to better characterize cloud and precipitation profiles of all conditions, including periods of heavy precipitation from storms, as well as validate-model simulations.
These data are provided by ASR-supported researchers, Zhe Feng of Pacific [...]
