ARM and ASR Community Members Honored at Annual Meetings

Published: 21 February 2023

The annual meetings of the American Meteorological Society (AMS) and American Geophysical Union (AGU) are more than opportunities for researchers to share their science with their peers and make new connections. Ten researchers with recent ties to the U.S. Department of Energy’s (DOE) Atmospheric Radiation Measurement (ARM) user facility and Atmospheric System Research (ASR) program received honors at the latest AGU and AMS annual meetings.

2023 AMS Awards

In January 2023, AMS award recipients were recognized at the society’s annual meeting in Denver, Colorado.

Six researchers from the ARM and ASR communities were honored during the event.

Jiwen Fan


Jiwen Fan, Sonia Lasher-Trapp, and ASR Program Manager Shaima Nasiri were among the 24 individuals recognized as part of the 2023 class of AMS Fellows. AMS fellowship honors are awarded for “outstanding contributions to the atmospheric or related oceanic or hydrologic sciences or their applications during a substantial period of years.”

Fan is a laboratory fellow and an earth scientist at Pacific Northwest National Laboratory in Washington state. At AMS, she gave a core science keynote presentation about the impact of aerosols on deep convective clouds and severe weather.

Sonia Lasher-Trapp

Fan has been a co-investigator on five ARM field campaigns, including ARM’s Green Ocean Amazon (GoAmazon2014/15) campaign, the recently completed TRacking Aerosol Convection interactions ExpeRiment (TRACER) in Texas, and the ongoing Surface Atmosphere Integrated Field Laboratory (SAIL) campaign in Colorado, among others. She previously served on ARM’s User Executive Committee and was a past recipient of a DOE Early Career Research Program grant.

Lasher-Trapp is a professor in the Department of Atmospheric Sciences at the University of Illinois Urbana-Champaign. She is leading a three-year ASR project combining data analyses and modeling from ARM’s 2018–2019 Cloud, Aerosol, and Complex Terrain Interactions (CACTI) campaign in Argentina to look at general trends of aerosol effects upon convective cold pools. At AMS, Lasher-Trapp gave an invited presentation on the effects of immersion-freezing ice-nucleating particles on CACTI thunderstorm simulations.

Shaima Nasiri

Lasher-Trapp is also a member of the ARM Science Board, an independent review board that ensures ARM is used to conduct the highest-quality science.

Nasiri is a program manager for DOE’s ASR program in Germantown, Maryland. She also currently co-leads several DOE initiatives focused on increasing diversity in climate and environmental sciences, including the Reaching a New Energy Sciences Workforce (RENEW) and Funding for Accelerated, Inclusive Research (FAIR) initiatives.

During AMS, Nasiri presented a poster that provided an overview of ASR, the relationship between ASR and ARM, and ASR-related funding opportunity announcements.


Bruce Albrecht

Bruce Albrecht, a professor emeritus in the atmospheric sciences department at the University of Miami’s Rosenstiel School, received the Carl-Gustaf Rossby Research Medal “for fundamental contributions to the measurement and understanding of boundary-layer clouds and the turbulent and microphysical processes controlling them.” The medal is awarded to individuals who have made outstanding contributions to the understanding of the structure or behavior of the atmosphere.

A pioneer in the study of marine clouds, Albrecht led the 1992 Atlantic Stratocumulus Transition Experiment (ASTEX) in the Azores, off the coast of Portugal. ASTEX demonstrated how important the Azores are to the atmospheric research community, as the islands are well suited for the measurement of low marine clouds and are heavily influenced by aerosols from across the globe.

More than 30 years after Albrecht led ASTEX, the Azores continue to serve as an important source of marine stratocumulus cloud data provided by ARM’s Eastern North Atlantic atmospheric observatory.


Venkatachalam (V.) Chandrasekar

Venkatachalam (V.) Chandrasekar was awarded the Verner E. Suomi Technology Medal, a medal awarded to individuals who have made a highly significant technological achievement in the atmospheric or related oceanic and hydrologic sciences. Chandrasekar was selected for the award in recognition of his “leadership in developing techniques to observe precipitation processes using dual-polarization and spaceborne radar.”

Chandrasekar, a professor of electrical and computer engineering and a Fellow of the Cooperative Institute for Research in the Atmosphere at Colorado State University, is a co-investigator for ARM’s SAIL field campaign.

At AMS, Chandrasekar gave a talk on the synergy found between radar observations from SAIL and the concurrent NOAA-led Study of Precipitation, the Lower Atmosphere, and Surface for Hydrometeorology (SPLASH).


Rebecca Adamns-Selin

Rebecca Adams-Selin received the Monthly Weather Review Editor’s Award “for thorough, thoughtful, and constructive reviews of numerous manuscripts on convective storms.” The award is presented to individuals who provide outstanding service to the AMS Monthly Weather Review journal.

Adams-Selin, a senior manager scientist at Atmospheric and Environmental Research Inc. in Massachusetts, leads a current ASR project using ARM data from Oklahoma. The project team is examining how the characteristics of midlatitude mesoscale convective system stratiform precipitation regions are generated and modified by low-frequency gravity waves, line-end vorticity-induced wind flows, and large-scale environmental conditions.

2022 AGU Awards

At its December 2022 fall meeting in Chicago, Illinois, AGU recognized its newest group of award recipients.

The honorees included four researchers with recent ties to ARM and ASR.


Andrew Gettelman and Wei-Kuo Tao were among the 54 individuals recognized as part of the 2022 class of AGU Fellows. The honor is awarded to AGU members who “embody AGU’s values by fostering equity, integrity, diversity, and open science; by mentoring; through public engagement; and in their communications.”

Andrew Gettelman

Since 2022, Gettelman has been an earth scientist at Pacific Northwest National Laboratory in Washington state. He received his AGU honor “for advancing our understanding of cold cloud physics in climate dynamics and the development of community Earth system models.” One of those models, the System for Integrated Modeling of the Atmosphere (SIMA), was the focus of Gettelman’s invited presentation at the AGU Fall Meeting.

While in his previous role at the National Center for Atmospheric Research in Boulder, Colorado, Gettelman participated in the Southern Ocean Clouds, Radiation, Aerosol Transport Experimental Study (SOCRATES). The large international multi-agency effort included collaboration with two ARM field campaigns in the region, the Macquarie Island Cloud and Radiation Experiment (MICRE) and Measurements of Aerosols, Radiation, and Clouds over the Southern Ocean (MARCUS).

Gettelman also served on the science team for ARM’s 2017–2018 Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) campaign. He previously was a member of ARM’s User Executive Committee and currently serves on the ARM Science Board.

Wei-Kuo Tao

AGU recognized Tao, a research meteorologist at NASA’s Goddard Space Flight Center in Maryland, “for seminal and pioneering contributions to understanding clouds and precipitation using advanced numerical modeling and satellite observations.”

Tao has been a principal investigator for multiple ASR-funded projects. His latest project analyzed the processes that govern the sizes of convective cloud shields using data from ARM’s GoAmazon field campaign in Brazil and Southern Great Plains (SGP) atmospheric observatory in Oklahoma.

During the AGU Fall Meeting, Tao gave an invited presentation on the Goddard Cumulus Ensemble, a cloud-resolving model developed and improved at NASA’s Goddard Space Flight Center over the past three decades.


Pierre Gentine

Pierre Gentine received the James B. Macelwane Medal for early career scientists who have made significant contributions to Earth and space science. Gentine was honored “for his fundamental research on land-atmosphere interactions and pioneering contributions to integrating machine learning concepts into climate modeling.”
