New Zealand Journal of Marine and Freshwater Research: Vol. GLORYS reanalysis project is carried out in the framework the European Copernicus Marine Environment Monitoring Service (CMEMS). To assist in understanding the differences in reconstructed states, we first present the main modelling and assimilation approaches that were employed, with an emphasis on those that play a primary role in affecting the representation of the Arctic sea ice cover (i . New insight of the West Tropical Atlantic Circulation based on 25 years of satellite altimetry, PIRATA data and GLORYS ocean reanalysis Fabrice Hernandez, Djoirka M. Dimoune, Florence Birol, Fabien Leger, Moacyr Araujo Motivation Data Results Summary Ocean processes and observing networks The Mercator Ocean global system at 1/12° is able to represent the ocean variability from the diurnal cycle to the interannual variability. DFS atmospheric reanalysis. i.e . GLORYS produces monthly global ocean reanalysis at eddy-permitting resolution from 1993 to 2010 18, while EN4 generates monthly data that covers the period between 1979 and 2010 19. from CMEMS ocean reanalysis GLORYS 3-hourly output of wave parameters (including partitionning wind-wave and swell partitions) : 20 parameters CMEMS catalogue WMEMS global wave reanalysis WAVERYS (1993-2019) SWH percentile 90th Average of SWH Validation with HY2A SWH indicates globally a scatter index of ~8.5% and Small bias of 5 cm 36 Full PDFs related to this paper. (2011) objective was to try to estimate the . 132-155. The IBI system provides blue and green ocean data The regional coverage for the Mediterranean Sea, which we call [MED] is 11°W-37°E / 30°N-46°N. The assimilation component of the Mercator Ocean . Ocean and sea-ice reanalyses (ORAs, or ocean syntheses) are reconstructions of the ocean and sea-ice states using an ocean model integration constrained by atmospheric surface forcing, and ocean observations via a data assimilation method (e.g., Storto and Masina, 2016 ). Overall, the Copernicus GLORYS reanalysis exhibits the better performance, with more realistic ocean variability and smaller biases in the water column structure. Ruth Mugford. BIORYS. BIORYS. Mercator-Ocean has developed a regional forecasting system at 1/12° resolution over the North East Atlantic (IBI: Iberia, Biscay and Irish), taking advantage of the recent developments in NEMO. The secondary peak, however, is only statistically significant at 90% in the GLORYS reanalysis. An upgraded version of the Euro-Mediterranean Center for Climate Change (CMCC) eddy-permitting global ocean reanalysis, named CMCC Global Ocean Reanalysis System (C-GLORS) version 4, was recently released. The reanalysis covers the meteorological satellite era (1982-2012). Figure 3: Time evolution of global mean temperature innovations (left) and residuals (right) in the global ¼° ocean reanalysis Glorys. ♦. This dataset provides simulated sea surface height (SSH) in a format similar to the future SWOT Level 2 (L2) altimetry data from the Poseidon 3C nadir altimeter. Mercator Ocean Reanalysis at ¼° GLORYS (1993-2015) Objectives •Reproduction of climatic signals on altimeter periods (from 1993 until present), with interannual variability and trend (essential variables, heat content, mass, sea ice, biogeochemistry…). This product also bears the name of WAVERYS within the GLO-HR MFC. BIORYS. the requirements of reanalysis projects (GLORYS - Global Ocean Reanalysis and Simulations project, Ferry et al., 2010) including validation, initialization and assimilation of mod-els (Mercator, Lellouche et al., 2012, this issue) and those of general oceanographic research studies, including ones on Over the last decade, performance of ocean reanalyses has improved thanks .

Maryland Simple Ocean Data Assimilation (SODA) Shriver, Jay¹, Richman, James², Metzger, E.¹, Hogan, Patrick¹, Smedstad, Ole³ ¹U.S. Evaluation of four global ocean reanalysis products for New Zealand waters-A guide for regional ocean modelling. The goal of the CMEMS global ocean reanalysis is to provide an eddy permitting (1/4°) global ocean simulation, covering the recent period during which altimeter data are available (period starting with In reply to GLORYS Reanalysis by G. Garric (not . . Overall, the Copernicus GLORYS reanalysis exhibits the better performance, with more realistic ocean variability and smaller biases in the water column structure. In the IBI reanalysis at 1/12°, the impact of removing the Argo data is illustrated on the model analysed temperature and salinity fields. GLORYS is jointly conducted by MERCATOR OCEAN, CORIOLIS, and CNRS/INSU. Tietsche, S., Balmaseda, M.A., Zuo, H. and Mogensen, K., 2015. The assimilation component of the Mercator Ocean . At the One Ocean Summit organised by France in Brest in February 2022, six European states (France, Italy . for correspondence to other global multi-year products like GLORYS. This regional forecasting system uses boundary conditions from the Mercator-Ocean global reanalysis (GLORYS: Global Ocean ReanalYses and Simulations). This reanalysis is based on an operational 3D ocean model with realistic forcing, bathymetry, baro-clinicity, and so on. The ECMWF OCEAN5 system is a new global eddy-permitting ocean-sea ice ensemble reanalysis analysis system. for correspondence to other global multi-year products like GLORYS. Installation, recovery, data acquisition, and processing of the CANEK group current-meter moorings were possible because of CICESE-Petr?leosMexicanos Grant PEP-CICESE 428229851 and the dedicated work of the crew of the B/O Justo Sierra and scientists of the CANEK group. Conclusion Marine Monitoring • WAVERYS is a CMEMS global wave reanalysis at 20 km (1993 -2018) that is particularly efficient for regions dominated by ocean currents and long swells • Very good results : ~8 % SI on global average (8% better that ERA 5 w. r. t HY 2 A altimeter) and a few cm of bias v WAVERYS is released since 3 rd December . Applied existing detection and tracking algorithm for oceanic eddies and applied it to the GLORYS ocean reanalysis dataset for the period 1993-2012, then examined potential reasons for seasonal and interannual variability in eddy characteristics such as size, intensity, and duration. GREP consists of current ocean reanalysis efforts from the Centro Euro-Mediterraneo sui Cambiamenti Climatici (CGLORS, Storto and Masina, 2016), the UK Met Office (FOAM, Blockley et al., 2014), Mercator Ocean (GLORYS, Garric et al., 2017), and ECMWF (ORAS5, Zuo et al., 2018, 2019). a.

The next version of the global high-resolution system will also include seasonal errors for in situ vertical profiles already used in the CMEMS eddy-resolving 1992-2016 reanalysis GLORYS at 1∕12 ∘ horizontal resolution, which is based on the system PSY4V3 and appeared in the CMEMS catalogue in April 2018. - GLORYS (Global Ocean ReanalYses and Simulations, reanalysis from Mercator-Ocean) - SODA (Simple Ocean Data Assimilation, university of Maryland) - ECCO (Estimating the Circulation and Climate of the Ocean)ECCO (Estimating the Circulation and Climate of the Ocean) Cabanes et al, 2008 : MOC variability is correlated with the NAO index In situ data: a third generation wave model that calculates the wave spectrum. 55, Special issue: The physics of New Zealand's shelf seas.
