Minute Sea-Level Analysis (MISELA): a high-frequency sea-level analysis global dataset

Abstract. Sea-level observations provide information on a variety of processes occurring over different temporal and spatial scales that may contribute to coastal flooding hazards. However, global research sea-level extremes is restricted hourly datasets, which prevent the quantification analyses at timescales between few minutes hours. These shorter-period processes, like seiches, meteotsunamis, infragravity waves, even dominate in low tidal basins. Therefore, new 1 min dataset – MISELA (Minute Sea-Level Analysis) has been developed, encompassing quality-checked records nonseismic oscillations tsunami (T<2 h) obtained from 331 tide-gauge sites (https://doi.org/10.14284/456, Zemunik et al., 2021b). This paper describes data quality control procedures applied dataset, world regional coverage sites, lengths time series. The appropriate for global, or local atmospherically induced high-frequency oscillations, should be included overall assessments.
