IGAC's biennial Open Science Conferences are the primary mechanism for dissemination of scientific information across our community. The conference is held jointly with iCACGP quadrennially. A special effort is made to engage early career scientists and scientists from emerging countries. Since 2004 the IGAC Early Career Program has been an integral part of the conference.

Atmospheric Chemistry from a Distance: Real Progress through Virtual Interaction


Held Virtually Globally

For the 2021 virtual conference, IGAC's scientific program will center its scientific program around its current working groups and activities.  This will highlight the exciting work being done as part of IGAC, grow the networks of these working groups and activities, and expose new scientists to the year-round work IGAC does. IGAC will also have an open science session for atmospheric chemistry research that does not fit into any current working groups or activities. We hope this will expose any gaps in IGAC's current activities and serve as a poll for the atmospheric community on the next big questions in atmospheric chemistry. 

Abstract submissions are closed, but registration for participation is open until September 1st! To register, click here. 

A note about our virtual conference:

IGAC prides itself on building community and fostering international collaboration in atmospheric chemistry. The IGAC Conference has historically been a welcoming space for scientists to create international networks. While conference networking looks a bit different in the virtual world, we are working to make the IGAC2021 conference as close to a regular IGAC conference as possible. None of our main sessions will overlap, which will allow everyone to participate in multiple sessions. We encourage you to select as many categories as you like when submitting your abstract. We are investigating ways to make the conference accessible across international time zones.  Side meetings and breakout sessions will still take place.

 If you’ve missed small-group coffee break chats and unplanned encounters in poster sessions, we want to facilitate these interactions. In addition to webinar software, we plan to use an online platform,, that allows chance conversations and informal meetings to occur throughout the conference timeline, in poster sessions and casually in the conference space between sessions.

There will also be an excellent early career researcher program held the week before the conference, focused on networking and career planning (registration to come, register your interest here) and general networking and side meetings throughout the main conference period.

We look forward to receiving your abstracts and interacting with you all virtually in September! For any concerns, please reach out to
