Data and code for Processing sensitivity of coastal tide level trends and shared variability around Taiwan

This dataset supports an analysis of processing sensitivity in monthly records from 11 Taiwan tide gauges during 2010–2025. It contains source-specific monthly tide observations, regional and station-associated satellite sea-level series, spatial-pairing inputs and weights, event and benchmark evidence registries, analysis scripts, and derived results. The analysis compares 24 configurations excluding unverified reference-change stress tests with all 42 configurations, HAC bandwidths of 6, 12, and 24 months, and circular-bootstrap block lengths of 6, 12, and 24 months. Scenario envelopes represent sensitivity to processing assumptions and are not confidence intervals. The tide records are not formally datum corrected, and atmospheric processing remains unmatched.
