Abstract. The sea level observations carried out at Trieste, Molo Sartorio, from 1869 to 2021 have been revised and updated. Information on the tide gauges and on the geodetic benchmarks on Molo Sartorio during that period have been collected. Basic quality checks have been applied. The hourly data for the 1917–1938 period, digitized from the original charts, have allowed us to build a time series of hourly sea level heights from 1905 to 2021. Gaps of up to 24 h have been filled by interpolation. The errors affecting the monthly and annual mean sea levels have been estimated. The availability of monthly and annual means prior to 1904 allowed us to build a mean sea level time series spanning 153 years, characterized by linear trends of an observed sea level of 1.36 ± 0.17 mm yr−1 and of an inverse-barometer-corrected sea level of 1.45 ± 0.13 mm yr−1. A significant acceleration of 0.008 ± 0.004 mm yr−2 was estimated from the inverse-barometer-corrected sea level time series. This data set represents the most up-to-date data set of sea level observations and ancillary information relative to the tide-gauge station of Trieste, Molo Sartorio. The data are available through SEANOE (https://doi.org/10.17882/62758, Raicich, 2022).

意大利莫洛萨尔托里奥的里雅斯特的海平面时间序列（1869-2021）

摘要。对 1869 年至 2021 年在莫洛萨托里奥的里雅斯特进行的海平面观测进行了修订和更新。收集了关于那个时期 Molo Sartorio 上的验潮仪和大地测量基准的信息。已应用基本质量检查。1917 年至 1938 年期间的每小时数据，从原始图表数字化，使我们能够建立从 1905 年到 2021 年每小时海平面高度的时间序列。最多 24 小时的差距已通过插值填补。已经估计了影响月平均海平面和年平均海平面的误差。1904 年之前月度和年度平均值的可用性使我们能够建立一个跨越 153 年的平均海平面时间序列，其特征是观测到的海平面 1.36 ± 0.17 mm yr−1 的线性趋势和反气压计校正海平面的线性趋势1.45 ± 0 的水平。13 毫米 yr−1。根据反气压计校正的海平面时间序列估计了 0.008 ± 0.004 mm yr-2 的显着加速度。该数据集代表了最新的海平面观测数据集和与的里雅斯特 Molo Sartorio 验潮站相关的辅助信息。数据可通过 SEANOE (https://doi.org/10.17882/62758, Raicich, 2022) 获得。
