British Oceanographic Data Centre record 10481032257 2025-02-11 publication 2024-11-28 creation 2024-11-28 revision EDMED7366 http://www.bodc.ac.uk/ Satellite-derived data and data used for satellite data validation from the SWOT-UK project. Validation sea level elevation data are from tide gauges re-referenced to ETRS89 (WGS84) This data covers the Bristol Channel, Severn estuary and river Severn. The bulk of the data spans the period from the beginning of 2022 to the end of July 2023, but the data used for the validation of the Cryosat2 satellite goes back to 2012. These data came from the Environment Agency and National Network of Regional Coastal Monitoring Programmes (Channel Coastal Observatory) APIs, with three addition Global Navigation Satellite Systems Interferometric Reflectometry (GNSS-IR) systems installed by the project team. The data were transformed to ETRS89 (WGS84) Ellipsoid using a software utility provided by the Ordnance Survey, for comparison to satellite altimetry data. Stations measuring relative to chart or stage datum were corrected to ordnance datum before transformation to ETRS89 (WGS84). The data are supplied as water surface elevation (altitude) in metres, relative to ETRS89 (WGS84) Ellipsoid. These real-time in situ data have not been corrected for atmospheric pressure, to match the total water level measurements of the satellite.

Data managers quality assure submissions and assemble the metadata necessary for curation. Submissions (as received) are placed in a long-term accession and stored in triplicate across multiple sites. Appropriate data are transferred into a standard internal format with source variable names mapped to controlled vocabularies, documentation assembled, and metadata loaded into BODC databases. Access to these data is through direct request, the BODC website and through partner repositories such as SeaDataNet. Access control is attained by assigning a data policy to each set of data and this policy is used to administer access when data are requested. Discovery metadata is aligned with EU INSPIRE (through MEDIN) and SeaDataNet community standards. Data are converted to open community formats including Ocean Data View ASCII and SeaDataNet NetCDF, with data described using terms from the NERC vocabulary server. BODC submission agreements are documented on the BODC website and customer service is assured with a dedicated requests team that serve data following local regulations including General Data Protection Regulation (GDPR) 2018 and Environmental Information Regulations (EIR) 2004. true This dataset was created by the organisations with the "originator" role in this metadata record following their in-house data processing and quality control procedures. The data were then provided to the British Oceanographic Data Centre (BODC) for long-term archive and data publication in the BODC Published Data LibraryInstrument(s) used to collect data: sea level recorders.
