From the Ameriflux website:
Once again, we will host the meeting in hybrid mode. This meeting is open to anyone who works with eddy covariance flux methods or datasets, including early career scientists!
A full in-person meeting will take place in the middle of Massachusetts, US, with visits to the historic Harvard Forest Research site. We are trying to arrange the plenary session again in an outdoor tent.
Presentations and breakout discussions will be open to virtual attendees as much as technically feasible. Certain agenda items (site visits, walks, in-person poster session) may not be accessible to virtual attendees (but if you have creative hybrid-meeting ideas, please reach out). Virtual attendance will be free this year. A virtual poster session will take place in the week after the in-person meeting, giving all a chance to attend.
