Abstract:

Data assembly and processing centers are essential elements of the operational oceanography infrastructure. They provide data and products needed by modeling and data assimilation systems they also provide products directly useable for applications. The paper will discuss the role and functions of the data centers for operational oceanography and describe some of the main data assembly centers developed during GODAE Argo and Coriolis data centers for in-situ data, SSALTODUACS and NAVOCEAN for altimetry and GHRSST for SST. An overview of other data centers wind and fluxes, ocean colour, sea ice will also be given. Major progresses have been achieved over the past 10 years to validate, intercalibrate and merge altimeter data from multiple satellites. Accuracy and timeliness of products have been improved and new products have been developed. The same is true for sea surface temperature data through the GHRSST Pilot Project. A breakthrough in processing, quality control and assembly for in-situ data has also been achieved through the development of the real time and delayed mode Argo data system. In-situ and remote sensing data are now systematically and jointly used for calibration, validation and long term monitoring of the quality and consistency of the global ocean observing system e.g. altimetry and tide gauges, Argo and altimetry, in-situ and satellite sea surface temperature data. Main results will be illustrated. We will also review the development and use of products merging in-situ and remote sensing data e.g. surface currents, 3D temperature and salinity fields derived from altimetry, joint use of sea surface temperature and ocean colour and altimeter data. Future issues and main prospects will be discussed.
