Meet Argonne National Laboratory's Evan Keeler, lead instrument mentor for ARM’s meteorological automatic weather station (MAWS)! The MAWS provides critical surface meteorological data for radiosonde launches. It also serves as a second source of basic surface meteorological (MET) data in conjunction with the MET system. The MAWS delivers precise, 1-minute averages of humidity, temperature, pressure, and wind speed and direction. Visit our website to learn more about the MAWS: https://bit.ly/40gE5sB #ARMData

New data from the Tethered Balloon System (TBS) Merged value-added product (TBSMERGED VAP) are available from flights at the ARM User Facility's Southern Great Plains (#ARMSGP) Central Facility near Lamont, Oklahoma. This product combines TBS instrument data and ground-based ceilometer measurements to facilitate the examination of cloud-base and boundary-layer heights while making it easier to access and use measurements from ARM TBS missions. ??

???? New Career Opportunities Available in Atmospheric Science! ???? The University of Colorado Boulder's Department of Atmospheric and Oceanic Sciences has two open positions for postdoctoral researchers. Successful candidates will work on a project to better understand the sensitivity and coupling of the Arctic's cryosphere to clouds and aerosols in the region. Learn how to apply for these positions, and view other current job openings on ARM's Careers page: https://bit.ly/41TldBP

With support from the U.S. Forest Service, which is hosting the Bankhead National Forest (#ARMBNF) atmospheric observatory in northern Alabama, ARM has erected a 140-foot (42.7-meter) tower near the observatory’s main site. Instruments on the tower will sample a variety of properties below, within, and above the forest ????canopy. Several instruments are now up on the tower, including multi-level meteorological instrumentation, infrared thermometers, and photosynthetically active radiation sensors.

As we turn the page on another chapter of ARM’s history, we say a heartfelt thank you to Dr. Jennifer (Jen) Delamere (left) for her dedication as the ARM User Executive Committee (UEC) Chair. From navigating the ever-evolving landscape of atmospheric research, to championing the voices of ARM users, Jen’s leadership has been invaluable. Her passion for science has left a lasting mark. As she passes the torch to Dr. Michael (Mike) Jensen (right), we know ARM’s UEC future is in great hands.

?? New Data Available!?? ARM has released a new contoured frequency altitude diagram (CFAD) data product from the Ka-Band ARM Zenith Radar (KAZR) that was utilized during the 2019–2020 Cold-Air Outbreaks in the Marine Boundary Layer Experiment (#ARMCOMBLE) near Andenes, Norway. The product, known as KAZRCFAD, includes joint histograms of best-estimate reflectivity and height and aims to facilitate comparisons between measured radar reflectivity and earth system model outputs using simulated joint histograms for more accurate cloud ?? analysis. ??
