Abstract

Since 2005 Medspiration, a project within ESA’s Data Utilisation Envelope, has been providing a service that prepares satellite observations of sea surface temperature (SST) for near-real time operational applications, using level-2 SST data generated by European agencies. Its work is performed within the framework of the Global high resolution SST pilot project (GHRSST-PP). Its key users are operational met-ocean agencies that require accurate and timely SST data from several satellites in a commonly readable format as input to numerical weather forecasting and for assimilation into ocean circulation forecasting models. Already several agencies, both in Europe and worldwide, rely on the Medspiration service, which is planned to transition into an operational SST thematic assembly centre (TAC) for the GMES Marine Core Service. This presentation outlines the impact of the Medspiration service, both for the producers of Marine Core Services and also for the downstream users of their products. It reviews the success of the GHRSST approach for enhancing the quality of SST data by combining multiple data inputs. It focuses particularly on how Medspiration has facilitated wider access to AATSR data, which are now being treated as a reference standard for bias correction of SST products from other sources, leading to the production of stable climate-quality SST analyses. Finally the presentation reflects generically on the importance of providing appropriate infrastructures for data dissemination, which encourage the complementary use of competing data products. Medspiration shows how this approach leads to resilience and reliability when Earth Observation data are required as inputs to operational tasks.
