# Observing Meteorological Tides: Fifteen Years of Statistics in the Port of La Spezia (Italy)
## 5 Conclusions
Measurements carried out between 21 and 29 June 2021 inside the port of La Spezia: (**a**) atmospheric pressure; (**b**) sea level (\(\Delta\)p = 7.4 hPa, \(\Delta\)h = 1.4 cm, \(J_{\rm ph}\) = 1.9 cm \(*\) hPa\({}^{-1}\)). Figure S43. Measurements carried out between 21 and 27 July 2021 inside the port of La Spezia: (**a**) atmospheric pressure; (**b**) sea level (\(\Delta\)p = 8.5 hPa, \(\Delta\)h = 16.7 cm, \(J_{\rm ph}\) = 2 cm \(*\) hPa\({}^{-1}\)). Figure S44. Measurements carried out between 31 July and 24 August 2021 inside the port of La Spezia: (**a**) atmospheric pressure; (**b**) sea level (\(\Delta\)p = 14 hPa, \(\Delta\)h = 23.4 cm, \(J_{\rm ph}\) = 1.7 cm \(*\) hPa\({}^{-1}\)). Figure S45. Measurements carried out between 18 and 25 September 2021 inside the port of La Spezia: (**a**) atmospheric pressure; (**b**) sea level (\(\Delta\)p = 11 hPa, \(\Delta\)h = 18.8 cm, \(J_{\rm ph}\) = 1.7 cm \(*\) hPa\({}^{-1}\)). **Author Contributions:** Conceptualization, M.S. and O.F. ; methodology, M.S. and O.F. ; software, M.S. and O.F. ; validation, M.S. and O.F. ; formal analysis, M.S. and O.F. ; investigation, M.S. and O.F. ; resources, M.S. and O.F. ; data curation, M.S. ; writing--original draft preparation, M.S. ; writing--review and editing, M.S. and O.F. ; visualization, M.S. and O.F. ; supervision, O.F. ; project administration, M.S. and O.F. ; funding acquisition, M.S. and O.F.

Part of this research was carried out when the first author was at OGS--National Institute of Oceanography and Applied Geophysics (Trieste, Italy). Finally, the authors thank the anonymous reviewers whose comments and suggestions helped improve this work. **Conflicts of Interest:** The authors declare no conflict of interest. Figures A1-A4 (in this Appendix A) and Figures S1-S45 (in the Supplementary Material) show data acquired during the events listed in Table A2; solid lines represent low-frequency components survived the Low-Pass filtering; dashed lines represent high-frequency components removed by the Low-Pass filtering.
