Announcement: 49th Global Monitoring Annual Conference (GMAC) 24 – 28 May 2021

The NOAA Global Monitoring Laboratory (GML) is pleased to announce details about the 49th Global Monitoring Annual Conference (GMAC) and continue our ongoing effort to collaborate and bring the long-term global monitoring community together each year.

The 2021 virtual GMAC (eGMAC) will be held on five consecutive days: Monday, May 24th through Friday, May 28th, 2021, beginning at 12:00PM Mountain Daylight Saving Time (UTC -6). Each session will be ~3 to 3.5 hours long. Sessions will be recorded to allow colleagues in all time zones to view the presentations after the session concludes.  

Each day will have the following format plus a few short breaks:

  • 6 scientific talks (12 minutes each, plus 3 minutes for questions)
  • Virtual discussion rooms with the oral presenters
  • Virtual poster session to include:
    • 90-second lightning talks for each poster to begin the session
    • Virtual presentation/discussion room unique to each poster

Registration is now open! If you plan to attend any of the sessions, please register on the eGMAC website:

Registration will be required to access links for the daily presentations and discussion rooms.

GML is happy to accept abstract submissions for oral and poster presentations again this year. Due to the virtual format, approximately 30 oral presentations will be chosen. All abstracts that are not chosen for oral presentations will be offered poster presentation slots. Poster presenters are encouraged to only submit one abstract unless they have a strong co-author that can host the virtual poster presentation room on their behalf.  

The eGMAC’s agenda is largely driven by the abstracts we receive – GML strongly encourages scientists at all points in their career to submit an abstract and we look forward to your contribution.

Abstract submission is now open! The abstract submission deadline is Monday, April 26th.  Submit your abstract at:
