    Mike Ritsche helps Argonne manage the Southern Great Plains atmospheric observatory, located across Oklahoma and Kansas.

Right now over 200 instruments are ticking around the clock across vast stretches of wheat fields and pastureland inside Oklahoma and Kansas. Their function — to take detailed measurements of our atmosphere — keeps them busy 24 hours a day, 365 days a year. And without them, scientists around the world would lack critical data they need to truly understand the atmosphere.

These instruments make up the Southern Great Plains (SGP) atmospheric observatory, the world’s largest and most extensive climate research facility. This year the site celebrates 25 years of operations, helping scientists gain vital insights into the Earth’s cloud, aerosol and atmospheric processes.

“SGP is the best, most advanced atmospheric research site in the world in terms of the variety of its atmospheric measurements, the measurement quality, staff expertise and the length of the data record.” - David Turner, NOAA meteorologist

The site, managed by Environmental Science Division researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, is the first and largest one established by the Department of Energy’s Atmospheric Radiation Measurement (ARM) Climate Research Facility. As a DOE Office of Science User Facility, ARM offers scientific data and support to advance scientific inquiry across a wide variety of fields.

The site’s more than 200 instruments measure the atmosphere in countless ways, including solar radiation, rain or snowfall, cloud properties, winds, pollution, humidity and temperature. Researchers glean these data to enhance climate and weather forecast models as well as studies in agriculture, cloud development, land –atmosphere interactions and severe storm processes.

“Individual researchers would not have the resources to measure the number of variables needed in analysis of complex atmospheric processes,” said Nicki Hickmon, associate director of operations for ARM.

“But for many researchers, measuring all these variables is critical to understanding what is going on. So providing those measurements really helps to feed the science.”

Measurements collected are freely accessible through the ARM’s Data Discovery portal.

The Southern Great Plains’ instruments extend from the site’s core facility to 25 other locations surrounding it. This design enables researchers to track how clouds, rainfall and other atmospheric phenomena move and evolve across wider areas.

Along with access to instrumental data, scientists can visit the site to conduct field campaigns - periods of time set aside to capture specific data at a set location. During these campaigns, researchers can bring in their own instruments or augment them with SGP’s observations.

“We’ve hosted people from all over the world and can run many campaigns at any given time, which is unique,” said Mike Ritsche, Argonne’s SGP site manager.

“These capabilities are made possible through our extensive support structures, including a shipping and receiving warehouse, an electronics repair shop and a dedicated team of experts available to help with logistics.”

Over the past 25 years, the site has hosted nearly 400 field campaigns. Meteorologist David Turner, a long-time user at the site and associate of ARM, is impressed.

“SGP is the best, most advanced atmospheric research site in the world in terms of the variety of its atmospheric measurements, the measurement quality, staff expertise and the length of the data record,” Turner said.

Turner, who works for the National Oceanic and Atmospheric Administration, says the value of ARM site observations are fundamental to scientific inquiry.

“ARM allows us to evaluate whether our current understandings of our world are correct. If not, then these observations can help us make improvements.”

The ARM Climate Research Facility is operated by nine DOE national laboratories, including Argonne National Laboratory, Brookhaven National Laboratory, Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory, Los Alamos National Laboratory, National Renewable Energy Laboratory, Oak Ridge National Laboratory, Pacific Northwest National Laboratory and Sandia National Laboratories.

Argonne National Laboratory seeks solutions to pressing national problems in science and technology. The nation's first national laboratory, Argonne conducts leading-edge basic and applied scientific research in virtually every scientific discipline. Argonne researchers work closely with researchers from hundreds of companies, universities, and federal, state and municipal agencies to help them solve their specific problems, advance America's scientific leadership and prepare the nation for a better future. With employees from more than 60 nations, Argonne is managed by UChicago Argonne, LLC for the U.S. Department of Energy's Office of Science.

The U.S. Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time. For more information, visit the Office of Science website.

How the Earth Stops High-Energy Neutrinos in Their Tracks

A research collaboration including scientists from Berkeley Lab has demonstrated that the Earth stops high-energy neutrinos - particles that only very rarely interact with matter.

Kentucky Researchers First to Produce High Grade Rare Earths From Coal

University of Kentucky researchers have produced nearly pure rare earth concentrates from Kentucky coal using an environmentally-conscious and cost-effective process, a groundbreaking accomplishment in the energy industry.

Watching Atoms Move in Hybrid Perovskite Crystals Reveals Clues to Improving Solar Cells

The discovery of nanoscale changes deep inside hybrid perovskites could shed light on developing low-cost, high-efficiency solar cells. Using X-ray beams and lasers, a team of researchers led by the University of California San Diego discovered how the movement of ions in hybrid perovskites causes certain regions within the material to become better solar cells than other parts.

Quantum Dots Amplify Light with Electrical Pumping

In a breakthrough development, Los Alamos scientists have shown that they can successfully amplify light using electrically excited films of the chemically synthesized semiconductor nanocrystals known as quantum dots.

A geospatial analysis determined the optimal distribution of sites needed to reliably estimate Alaska's vast soil carbon.

Strain-Free Epitaxy of Germanium Film on Mica

Germanium was the material of choice in the early history of electronic devices, and due to its high charge carrier mobility, it's making a comeback. It's generally grown on expensive single-crystal substrates, adding another challenge to making it sustainably viable for most applications. To address this aspect, researchers demonstrate an epitaxy method that incorporates van der Waals' forces to grow germanium on mica. They discuss their work in the Journal of Applied Physics.

Detailed View of Immune Proteins Could Lead to New Pathogen-Defense Strategies

Biologists at Berkeley Lab and UC Berkeley used cryo-EM to resolve the structure of a ring of proteins used by the immune system to summon support when under attack, providing new insight into potential strategies for protection from pathogens. The researchers captured the high-resolution image of a protein ring, called an inflammasome, as it was bound to flagellin, a protein from the whiplike tail used by bacteria to propel themselves forward.
