Hello Rick, I think we have some cbc files which are properly detided. The attached plots have time in days on the x-axis (starting on May 27) and boundary node number on the y-axis. The signal appears to be largely non-tidal. Does this look like what you are seeing? We are now working on the north flank with the gbk1 mesh. Our current forecast runs cold start on May 24. We have the gbk1 files you sent starting May 27. Could you send us catch-up hindcast files for the 24th through the 26th? Thanks, Dennis
