Editing Global mean sea level (section)

== Observational Status ==
Monitoring of global mean sea level is ongoing and supported by established satellite altimetry missions coordinated by NASA and other agencies, with data archived and distributed through PO.DAAC. Tide gauge networks provide complementary historical records. Current observational capabilities allow for near-real-time tracking of sea-level changes and improved understanding of underlying processes. Future SIGNAL releases may incorporate enhanced spatial resolution, integration with additional oceanographic parameters, and refined boundary definitions as scientific understanding advances.
