[pam-users] Due 08/05/2026: Call for AGU Abstracts: Session A022 - Advancing Understanding of Combustion Aerosols and Their Impacts on Earth's System

[pam-users]

Dear PAM community,
We would like to draw your attention to our session at the 2026 AGU Fall Meeting titled “A022 - Advancing Understanding of Combustion Aerosols and Their Impacts on Earth's System”, convened by Zezhen (Jay) Cheng (EMSL/PNNL), Douglas Hamilton (NC State University), Rajan Chakrabarty (Washington University in St. Louis), Alla Zelenyuk-Imre (ACES/PNNL), and Yaowei Li (University of Toronto). We encourage you to submit your abstract to this session and share your insights and findings with an esteemed audience. If you know any colleagues who might also be interested in submitting abstracts, we kindly ask you to extend this invitation to them. We look forward to seeing you in San Francisco this December!

More details can be found HERE<https://agu.confex.com/agu/agu26/prelim.cgi/Session/281192> and at the end of this email.


Thank you very much for considering our session!
Sincerely,

Zezhen (Jay) Cheng (EMSL/PNNL)
Douglas Hamilton (NC State University)
Rajan Chakrabarty (Washington University in St. Louis)
Alla Zelenyuk-Imre (ACES/PNNL)

KEY INFORMATION:


  *   Abstract Due: Wednesday, August 5th, 2026 at 23:59 EDT/3:59 +1 GMT
  *   Session ID: 281192
  *   A022 - Advancing Understanding of Combustion Aerosols and Their Impacts on Earth's System
  *   Session Description:

Combustion aerosols, emitted directly from wildland fires, residential burning, industrial activities, and vehicular emissions, and formed secondarily through atmospheric aging of combustion-derived organic gases, are major contributors to atmospheric aerosols. They influence Earth's energy balance through radiative effects and aerosol-cloud interactions, affect ecosystem nutrient cycling, and pose risks to human and wildlife health. Yet their impacts on the Earth system remain poorly constrained due to key uncertainties, including, but not limited to, their formation and source contributions, physical and chemical properties, atmospheric transformation and transport, quantification of the spatial and temporal distribution of combustion aerosols, and their representation in models. To address these knowledge gaps, we invite laboratory, field, remote-sensing, and modeling studies on (1) combustion aerosol sources, formation, aging, and transport; (2) quantification of combustion aerosols' distribution, composition, mixing state, toxicity, and optical, chemical, and microphysical properties; and (3) parameterizations or representations of combustion aerosols in models.

  *   Invited Speakers:
     *   Prof. Allan K. Bertram, University of British Columbia
     *   Dr. Jiwen Fan, Argonne National Laboratory

Subject: [pam-users] Update on PAM Support

Dear PAM Community,

We are writing to you today to let you know that Andy Lambe has started a new position and will no longer be working with the PAM at Aerodyne. After all of his amazing work on developing and characterizing the PAM, it will be difficult to fill his shoes, but Chenyang Bi and I (Mitch Alton) will be taking over his duties from here on. We hope to bring the same passion and excitement to the community that Andy brought to the community and are looking forward to working with you all.

The main implication for this change is that all support/purchase/application questions and inquiries should be directed to support at aerodyne.com<mailto:support at aerodyne.com>. This will help us keep things organized so we respond to you in a timely manner.

If you have any questions or concerns, please feel free to reach out.

Best,
Mitch Alton and Chenyang Bi
