The NOAA Weather Program Office is pleased to announce the 2021 Subseasonal Experiment (SubX) Current and Potential Users Forum, scheduled for August 24 - 26, 2021. The goals of this virtual workshop are to encourage sharing of practices among SubX users, and to identify barriers to adoption by new users.

Each day of the workshop will feature plenary sessions highlighting the features of SubX and how it is currently informing operations, applications, and research. There will also be scheduled time during each session for more detailed discussions about current and potential future SubX use. 

Please complete this form to register for the Forum.  This registration is needed even if you previously filled out the pre-registration form earlier. The meeting link and final agenda will be distributed prior to the event. Feel free to circulate this announcement to your networks. 

If you have any questions, please contact Mark Olsen (
