Abstract
The Puertos del Estado SAMOA coastal and port ocean forecast service delivers operational ocean forecasts to the Spanish Port Authorities since 01/2017 (originally set-up for 9 ports). In its second development phase (2019–2021), the SAMOA service has been extended to 31 ports (practically, the whole Spanish Port System). Besides, the next generation of the SAMOA service is being developed. Research is being focused on (1) updating atmospheric forcing (by combining the AEMET HARMONIE 2.5 Km forecasts and the IFS-ECMWF ones), (2) upgrading the circulation model (ROMS), and (3) testing new methodologies to nest SAMOA systems in the Copernicus IBI-MFC regional solution (with emphasis on its 3D hourly dataset). Evaluation of specific model upgrades is here presented. Model sensitivity tests have been assessed using the available in-situ and remoted sensed (i.e., RadarHF) observations. The results show that SAMOA outperforms IBI-MFC in sea level forecasting at meso- and macro-tidal environments. Improvements by the herein proposed upgrades are incremental: some of these set-ups were used in the last SAMOA operational releases (i.e., the SAM_INI and the SAM_ADV ones; the later currently in operations), whereas the latest test (SAM_H3D) ensures more nesting consistency with the IBI-MFC and improves significantly surface currents and sea-surface temperature simulations.
Highlights
Operational oceanography, as defined by EuroGOOS (European Global Ocean Observing System [1]) is the activity of systematic and long-term routine measurements of the ocean and atmosphere, and their fast interpretation and dissemination
Results are split in two Subsections: Section 4.1 gives information on the SAM_INI, SAM_ADV performances for the June 2019 period, at the 9 original SAMOA-1 domains: Barcelona (BCN), Tarragona (TAR), Bilbao (BIL), Almería (ALM), Ferrol (FER), La Gomera (GOM), Gran Canaria (GCA), Santa Cruz de la Palma (PAL), Tenerife (TEN); whereas Section 4.2. assesses SAM_ADV, SAM_H3D and IBI_PHY from October 2019 to October 2020 at 5 SAMOA domains (i.e., BCN, TAR, BIL, ALM and GCA)
Impacts in SAMOA Solutions Related to Changes in the Open Boundary Condition (OBC) Treatment and the Use of a Bulk Formula to Deal with Atmospheric Forcing (SAM_ADV vs. SAM_INI)
Summary
Operational oceanography, as defined by EuroGOOS (European Global Ocean Observing System [1]) is the activity of systematic and long-term routine measurements of the ocean and atmosphere, and their fast interpretation and dissemination. End-users and stakeholders are key to sustain operational oceanographic systems, as well as to foster new ones. A complete list of the range of services and a description of how end-users and stakeholders use these operational services goes beyond the scope of this introduction (see Schiller et al, 2018 and Davidson et al, 2019 for more extensive reviews [2,3]). In general, primary sectors supported by operational oceanographic services are those related to improve the safety and efficiency of marine activities. Many of the existing operational oceanographic services focuses on regional coastal waters, where most of the protection of marine environments in sensitive habitats and human activities occurs (De Mey-Frémaux et al, 2019 [4])
