8. Next steps Selection of sites to match to GIA
Carefully check the logs of the selected sites (e.g, CHUR has an apparent discontinuity but date does not correspond with antenna change (there was one a few months before)
Check local stability/non-GIA effects at sites. Correlated noise models let us assess “linear” motion sites but these can be affected by other processes
Expansion of GIA model space (minima for fits are occurring at edges of model space). More complex models?
