Dear Colleagues,

As part of the 2020 Fall Meeting of the AGU that will mostly be a virtual meeting, we would like to draw your

attention to the session on:

G009 - Reference Frames: Determination, Usage, and Application

We welcome papers that discuss the final aspects of the reprocessing in preparation for ITRF2020,

and we hope each of the techniques can present a status report on where they stand.

We welcome papers that discuss innovative results related to the determination of the reference frame, and

papers that demonstrate who the TRF and its regional manifestations are of applicability to civil society.

We understand that people are distracted and worried by the Covid-19 pandemic, and
probably dealing with the difficulties of working remotely away from direct contact with colleagues
and increased responsibilities for care of family members and children who cannot go in person
to school. We hope nonetheless that they will avail themselves of the opportunity to meet as
a community in this Reference Frame session, as it will be really the only forum we will have to
meet as a global community for the entire year, and in advance of what we hope will be an on-time
submission of the contributions for ITRF2020.

Best regards
