The document describes the quality of the Delayed Mode Multi-Year (MY) WAVE product delivered by the Copernicus Marine Service In Situ Thematic Assembly Centre (In Situ TAC). This document applies to the product INSITU_GLO_WAV_DISCRETE_MY_013_045 described in Copernicus Marine Service Catalogue. This product integrates observations aggregated and validated from the Regional EuroGOOS consortium (Arctic-ROOS, BOOS, NOOS, IBI-ROOS, MONGOOS) and Black Sea GOOS as well as from National Data Centres (NODCs), JCOMM global systems (OceanSITES, DBCP) and the Global telecommunication system (GTS) used by the Met. Offices. The In Situ TAC relies on observing systems maintained by institutes that are not part of the In Situ TAC, and Copernicus Marine Service is not contributing to the maintenance and setting up of the observing systems it uses. The Multi-Year WAVE product is a global product and provides two kinds of files: one with integrated parameters, with the string “TS_MO” in the filename (TS: Time Series, MO: Mooring), computed from the wave spectrum (e.g. significant wave height, peak period, mean direction) or zero crossing parameters (e.g. maximum wave height, mean height) and another one with the string “WS_MO” in the filename (WS: Wave Spectra, MO: Mooring) with the spectral information (scalar spectrum and directional functions like mean direction and angular spreading depending on the frequency). The files with integrated parameters contain also other physical and meteorological variables measured by the same platform. The complete list of variables distributed by the In Situ TAC can be found in the Copernicus Marine In Situ TAC physical parameters list (https://doi.org/10.13155/53381). Each file contains only the wave parameters provided by the platform which is a subset of the complete list of wave parameters. The Production Unit performs the wave validation in a centralized way twice a year, then the product is assessed through the metrics described in Section

The Copernicus Marine Environment Monitoring Service (CMEMS) provides regular and systematic reference information on the physical and biogeochemical ocean and sea-ice state for the global ocean and the European regional seas. CMEMS serves a wide range of users (more than 15,000 users are now registered to the service) and applications. Observations are a fundamental pillar of the CMEMS value-added chain that goes from observation to information and users. Observations are used by CMEMS Thematic Assembly Centres (TACs) to derive high-level data products and by CMEMS Monitoring and Forecasting Centres (MFCs) to validate and constrain their global and regional ocean analysis and forecasting systems. This paper presents an overview of CMEMS, its evolution, and how the value of in situ and satellite observations is increased through the generation of high-level products ready to be used by downstream applications and services. The complementary nature of satellite and in situ observations is highlighted. Long-term perspectives for the development of CMEMS are described and implications for the evolution of the in situ and satellite observing systems are outlined. Results from Observing System Evaluations (OSEs) and Observing System Simulation Experiments (OSSEs) illustrate the high dependencies of CMEMS systems on observations. Finally future CMEMS requirements for both satellite and in situ observations are detailed.

The document describes the Quality of the Delayed Mode or REProcessed (REP) WAVES product delivered by the CMEMS In Situ Thematic Assembly Center (In Situ TAC or INSTAC). The following document applies to the following list of products described in CMEMS Catalogue: - Product name: Global Ocean - Delayed Mode Wave product - Product code: INSITU_GLO_WAVE_REP_OBSERVATIONS_013_045 - Delivery Time: twice a year since 2019 This product integrate observation aggregated and validated from the Regional EuroGOOS consortium (Arctic-ROOS, BOOS, NOOS, IBI-ROOS, MONGOOS) and Black Sea GOOS as well as from National Data Centers (NODCs), JCOMM global systems (Argo, GOSUD, OceanSITES, GTSPP, DBCP) and the Global telecommunication system (GTS) used by the Met Offices. Data are distributed on full level (no interpolation). They are available in a dedicated directory to waves (INSITU_GLO_WAV_REP_OBSERVATIONS_013_045) of CMEMS Dissemination System in one file per platform. This directory is updated twice a year since 2019. Four of the INSTAC regions (BAL, NWS, IBI and MED) are performing their own wave validation over the data contained in their respective files (“BO_”, “NO_”, “IR_” and “MO_”). These REP files are distributed also in the corresponding REP regional directories. The GLOBAL Production Unit gets these files together with the validated “GL_” files and distributes the final WAVES product in the dedicated directory mentioned above.
