Network of active tide gauge stations - Observations
Network of active tide gauge stations and corresponding near-real-time (NRT) sea surface height (SSH) observations.
SSH observations are timestamped in Coordinated Universal Time (UTC, ISO 8601) and expressed in metres relative to the Portuguese Chart Datum (ZH) reference surface, identified by the vertical coordinate reference system EPSG:10349.
Processing levels follow an internal convention. Level 1 corresponds to data without quality control (QC). Level 2 corresponds to data with automatic QC (e.g., range checks, spike detection and temporal-consistency tests).
Active tide-gauge stations:
- tide_obs_stations_nrt
Currently available data:
- tide_obs_data_nrt_l1 — NRT data without QC (L1), sampled at 10- or 60-second intervals, with a latency of 1 minute and a rolling temporal window of 8 days
