- Though ARGOSS database is copyrighted, statistics generated from the layer Wind and wave climate are copyright-free and are therefore publicly available inside and outside the European Commission.
Though ARGOSS database is copyrighted, the extrapolated data on tidal range derived from EUROSION are copyright-free and are therefore publicly available inside and outside the European Commission.
As a EUROSION assignment, the layer Sea level rise is publicly available inside and outside the European Commission. -
Methodology:
Source data have been severely checked and corrected with observation of tide gauges. Double control on the quality of the produced database is currently ensured on wind and wave climate as well as tidal range. The overall accuracy of tidal range estimates lies between 10 and 15%. Residual Mean Square Error (RMSE) of wave height estimates does not exceed 15%, though the RMSE of wind speed does not exceed 20%.

Data sources
EUROSION was a project commissioned by the General Directorate Environment of the European Commission 2002-2004.
1) Wave and wind climate: Data were entirely generated from the EUROSION project. The parameters listed above were statistically processed from the database waveclimate.com distributed by the dutch company ARGOSS. waveclimate.com database contains up to 17 years of wind- and wave data (1985-2001). Observations of wave height and wind speed come from altimeters carried by ERS-1, ERS-2, Topex/Poseidon and Geosat satellites. The scatterometer sensors onboard ERS-1 and ERS-2 supplied the wind speed and wind direction data. Wave spectral parameters were derived from spectra of Synthetic Aperture Radar (SAR) imagettes collected by ERS-1 and ERS-2 using an algorithm developed by ARGOSS [Mastenbroek and de Valk, 2000]. Production of statistical estimate for the parameters listed above were carried out over boxes of 200kmx200km. Each box overlaps with the adjacent boxes with an approximative 50% rate, and results are attached to the box centre (see screenshot above). As a consequence, data are provided with a 100km resolution along the European coast.
2) Data on tidal range at the 237 locations are extrapolated from the database "tidal-info.com" distributed by ARGOSS. This database contains tidal harmonics for the eight most important components, i.e. M2, S2, N2, K2, K1, O1, P1 and Q1. The harmonics were computed by assimilating eight years of radar altimeter orbit height measurements and tide gauge measurements from approximately 7300 coastal stations into a shallow-water tidal model. The satellite measurements give a good overview of the tidal patterns on deep water, whereas the stations give accurate information for certain locations close to the shoreline. The combination of the two, assimilated in a tidal model, provides good information in shallow coastal seas where tidal effects are most prominent.
3) Relative sea level rise (RSLR) at the 237 locations are extrapolated from the digitization of two maps, namely : - the map by [Douglas et al., 2001] which provides an estimate of RSLR for the whole of Europe - the map by [Lambeck et al., 1997] which covers a smaller area in more detail, i.e. the North Sea.

Additional information
These locations are situated 50 to 100 km away from the shoreline. Distance from one location to another location is approximately 100 km. Data contained in this layer are threefold: 1) Wave and wind climate. 2) Mean tidal range. 3) Relative sea level rise.
Geographical coverage note: data set covers locations situated 50 to 100 km away from the shoreline of EU-25.
Concerning the layer "Wave and wind climate": For each location, the data included in this layer provide the following parameters: - average wind speed - wind speed exceeded by 10% of the measurements - wind speed exceeded by 1% of the measurements - average wave height - wave height exceeded by 10% of the measurements - wave heights exceeded by 1% of the measurements - average wave period - wave period exceeded by 10% of the measurements - wave period exceeded by 1% of the measurements These parameters are provided for the following directional sectors: 0, 45, 90, 135, 180, 225, 270, and 315 degrees.
