Below meta data is shared on the datasets included in BlueEarth Data including further reading and information about the dataset validity and quality, where available.

DatasetDescriptionMore information
Currents, Water level, Storm Surge, Tide

Water level, storm surge, tide and current forecasts from the operational Global Storm Surge Information System (GLOSSIS) using Deltares’ Global Tide and Surge Model (GTSM).

This includes 10 day forecasts at hundreds of nearshore locations across the world. Click here for more information about GLOSSIS.

Maximum water levelsMaximum water levels for return periods of 2 years, 5 years, 10 years, 25 years, 50 years, 75 years and 100 years, based on a reanalysis with Deltares’ Global Tide and Surge Model (GTSM).The return periods are derived from a 38 year reanalysis with the GTSM, using ERA5 meteorology as input and with a Gumbel model fitted to the data. See the Wiki for further information about the GTSM, this reanalysis and further climate change scenarios carried out using this model.
Tidal indicatorsTidal indicators as calculated using Deltares’ Global Tide and Surge Model (GTSM).Included are the Highest Astronomical Tide (HAT), the Lowest Astronomical Tide (LAT), the Mean Higher High Water (MHHW), the Mean Lower Low Water (MLLW), the tidal range (Range) and the Mean Sea Level (MSL).
Shoreline Monitor
Historic shoreline changes between 1985 - 2016 based on satellite-derived shorelines. Annual time series with an alongshore resolution of 500m along the world's coastline

Satellite-derived shoreline change rates based on linear fit on annual shorelines between 1984 and 2017 presented for every 500 m alongshore with global coverage.

Air temperatureAir temperature forecasts by NOAA’s Global Forecasting System (GFS).See https://www.ncdc.noaa.gov/data-access/model-data/model-datasets/global-forcast-system-gfs for more information about NOAA’s GFS model.
DischargeDischarge forecasts by the Global Fluvial Forecasting System (GLOFFIS) run by Deltares, which runs global WFLOW models. This includes real-time forecasts at hundreds of locations across the world.See the Wiki for further information about GLOFFIS, and to find out more about the validity and quality of this dataset.
Wave and wind climateAnalysed wind and wave data from the raw data of ECMWF (ERA5) and NCEP between 1979 until present. The following information are presented with global coverage: Wind roses (wind speed and direction) and wave roses (wave height, period and direction) and 90th percentiles and extreme values (wind speed and wave height).See the Wiki for further information about the MetOcean Database, and to find out more about the validity and quality of this dataset.
BathymetryTopographic and bathymetric data from the General Bathymetric Chart of the Oceans (GEBCO). GEBCO’s gridded bathymetric data set, the GEBCO_2019 grid, is a global terrain model for ocean and land at 15 arc-second intervals, obtained from the GEBCO Compilation Group (2019) GEBCO 2019 Grid.(doi:10.5285/836f016a-33be-6ddc-e053-6c86abc0788e).
ElevationMerged open source topographic and bathymetric data from multiple sources.Topographic data includes: ALOS DSM, AHN Netherlands, Greenland DEM, USGS NED, Canadian DEM, Australian DEM, and REMA Mosaic. Bathymetric data from: GEBCO and EMODnet.
