🚨 New Data Alert!🚨

The Microwave Radiometer Retrievals value-added product (MWRRET VAP) is now available for multiple ARM Mobile Facility deployments, including the pictured 2024–2025 Cloud And Precipitation Experiment at kennaook (CAPE-k) in northwestern Tasmania. MWRRET provides improved retrievals of precipitable water v***r and liquid water path—key variables for understanding radiative transfer in clouds and the atmosphere. Available as .c2-level files, the data incorporate improved instrument offsets and cloud-layer information to enhance retrieval accuracy. 💧🌥️

What can a DOE Science Undergraduate Laboratory Internship (SULI) look like? For Cheyanne Williams, a student at Penn State, it meant getting hands-on experience working with real atmospheric data from ARM. 🎈🔬

During her SULI internship at Pacific Northwest National Laboratory, Cheyanne worked with data collected by ARM tethered balloon systems (TBS) during the Coast-Urban-Rural Atmospheric Gradient Experiment (CoURAGE) in the Baltimore, Maryland, region, gaining valuable experience in atmospheric research.

Hear from Cheyanne about her internship, then consider where a SULI could take you! 🌎

Wrapping up our recognition of 2026 ARM Service Award recipients, we're spotlighting ARM’s tethered balloon system (TBS) team for its extraordinary year of operational achievement and scientific innovation resulting in important data for the user community! 🎉

Dennis De Smet, Dari Dexheimer, Casey Longbottom, Brent Peterson, Carlos Ruiz, Steven Storch, Matt Tezak, and Rip Winckel of Sandia National Labs completed hundreds of TBS flights across multiple ARM sites and helped conduct the first combined TBS and ArcticShark uncrewed aerial system flights at ARM’s Bankhead National Forest atmospheric observatory.

The team also advanced ARM’s commitment to safe and sustainable operations through Federal Aviation Administration-recognized safety practices and the implementation of a helium reclamation system.

Congratulations to the TBS team and all of ARM’s 2026 Service Award recipients and nominees. We appreciate you and the impacts your work has had on ARM and its users! 🏆👏

Continuing our celebration of ARM’s 2026 Service Award recipients, we’re recognizing the radar data mentor team for its outstanding contributions to ARM’s data capabilities! 🎉 Min “Mindy” Deng of Brookhaven National Laboratory and Alyssa Matthews, Marqi Rocque, and Eddie Schuman of Pacific Northwest National Laboratory were recognized for their collaboration and technical innovation in advancing ARM’s radar data processing capabilities.

The mentors developed and implemented calibrated, quality-controlled b-level processing workflows for many of ARM’s radar systems, creating more consistent and scalable approaches that improve both data quality and operational efficiency. Their work has enabled the first-time release of numerous b-level radar data sets, a major step forward for ARM’s radar data capabilities and a lasting resource for the scientific community. 📡

Congratulations, Mindy, Alyssa, Marqi, and Eddie, and thank you for your outstanding contributions to ARM and its users! 🏆👏

What’s happening between the ground and the atmosphere? 🌎💨 ARM’s eddy correlation flux measurement system (ECOR) helps scientists find out!

The ECOR measures how heat, moisture, carbon dioxide, and wind move between the Earth’s surface and the air above it, providing new measurements every 30 minutes.

🎥 Hear from ARM’s ECOR lead mentor, Ryan Sullivan at Argonne National Laboratory, to learn how this instrument works and why these measurements matter.

ARM congratulates former director James Mather on being named a 2027 recipient of the American Meteorological Society (AMS) Cleveland Abbe Award for Distinguished Service to the Atmospheric and Related Sciences. AMS selected Jim for his “exceptional, sustained service that has strengthened the infrastructure, integrity, accessibility, and scientific impact of one of the atmospheric sciences’ most important observational user facilities.” Congratulations, Jim, on this well-deserved honor!

Congratulations to PNNL atmospheric scientist Jim Mather who has been selected to receive the American Meteorological Society (AMS) Cleveland Abbe Award for Distinguished Service to the Atmospheric and Related Sciences.

The award recognizes Mather’s scientific impact and service to the ARM User Facility. Mather joined ARM in 1994 as a postdoctoral researcher and recently retired after 20 years as the user facility’s director. He will retire from PNNL this fall.

Graduate students at Texas Tech University got hands-on research experience using ARM data, including observations from the recent CoURAGE field campaign in the Baltimore, Maryland, area. Students explored everything from turbulence and low-level jets to boundary-layer changes, turning classroom concepts into real-world research. 🌎📊

See how ARM data are helping train the next generation of atmospheric scientists! 👇

We have more congratulations to give! 🎉 Today, we congratulate ARM’s Data Quality (DQ) Office team, Corey Godine, Randy Peppler, David Rose-Franklin, James Schneider, and Alyssa Sockol from the The University of Oklahoma and Oak Ridge National Laboratory, on receiving a 2026 ARM Service Award. Presented July 21 during the Joint ARM/Atmospheric System Research (ASR) Principal Investigators Meeting, the awards recognize staff for outstanding service and contributions to ARM and its user community.

The DQ Office team was recognized for its exceptional leadership and resilience during a period of significant organizational change, maintaining ARM’s high standards for data quality operations while onboarding new staff, modernizing DQ Office tools, and strengthening workflow reliability.

Congratulations to the DQ Office team on this well-deserved recognition and thank you for strengthening the foundation of ARM’s data quality operations! 🏆👏

🎉 Congratulations to ARM’s development operations team, Michael Giansiracusa, David Rose-Franklin, and Chris Vernon from Oak Ridge National Laboratory, on receiving a 2026 ARM Service Award! Announced July 21 during the Joint ARM User Facility/Atmospheric System Research (ASR) Principal Investigators Meeting, the annual awards recognize outstanding service and contributions to ARM and its users.

ARM’s development operations team was honored for transforming how software and web applications are developed, deployed, and maintained at the ARM Data Center. The team’s leadership in establishing scalable, secure infrastructure and migrating the data center’s application stack to Kubernetes clusters has improved the reliability, observability, and long-term sustainability of ARM’s software ecosystem.

Congratulations, Michael, David, and Chris, on this well-deserved recognition! 🏆👏
