Delayed-mode reprocessing of in situ sea level data for the Copernicus Marine Service 

Jue Lin-Ye, Begoña Pérez Gómez, Alejandro Gallardo, Fernando Manzano, Marta de Alfonso, Elizabeth Bradshaw, and Angela Hibbert

Abstract. The number of tide gauges providing coastal sea level data has significantly increased in recent decades. They help in the issue of coastal hazard warnings, the forecasting of storm surges and tsunamis, and in operational oceanography applications. This data is often automatically quality controlled in near-real-time, as is the case in the Copernicus Marine Service. However, machine and visually inspected validation of historical sea level time series from these platforms is required. It has long been requested by the oceanographic community at large. As a result, a new initiative seeks to provide such validated data for the Copernicus Marine Service, by developing a new delayed-mode reprocessed in-situ sea level product. The existing software for the near-real-time product has been adapted to this end. After being visually controlled by a team with expertise in sea level reprocessing, the new product was launched in November of 2022. The entire reprocessing is discussed, in detail. An example of the information that can be extracted from the delayed-mode product is also given.

Short summary
The historical sea level measurements in the Copernicus Marine Service have been machine and visually inspected. The existing software for the near-real-time product has been adapted. The new product was launched in November of 2022, readily available for the general public. It helps in the issue of coastal hazard warnings, the forecasting of storm surges and tsunamis, and in operational oceanography applications.
