Model validation and finfish farms modelling output data in Kuwait Bay 2017-2019 dataset https://portal.medin.org.uk/portal/start.php?tpc=009_CEFAS0aeb2fe3-84aa-4dea-8036-10d2ef10cdab This data refers to a numerical model validation, in Kuwait Bay, for both the hydrodynamics and the biogeochemistry. Also, there is a dataset regarding finfish farms modelling. Different types of data have been used for the model set up and observations for the model validation: Physical and biogeochemical observations: data from the Kuwait Environment Public Authority (KEPA) at various monitoring stations for more than 30 years, as part of KEPA’s long-term water quality monitoring programme (`http://www.emisk.org/emisk/`_ ). Tidal velocities and water levels collected by the Kuwait Institute for Scientific Research (KISR). Bathymetry data: was the same as used by Bacon et al. (2014), which was based on compilation of a single beam bathymetry survey conducted in May 2014, by the authors, and complemented with digitised sections of a hydrographic chart of the area (Mina Az Zawr to Al Basrah and Bushehr-UKHO2884) (www.toddchart.com). Tidal forcing: was obtained from the OTPS regional product for the Persian Gulf at 1/60 degrees resolution (`http://volkov.oce.orst.edu/tides/PerS.html`_) Temperature and Salinity: data from the global ECMWF reanalysis model ORAP5.0, which can be downloaded from `http://icdc.cen.uni-hamburg.de/1/projekte/easy-init/easy-init-ocean.html?no_cache=1`_ . Meteorological forcing: obtained from the European Centre for Medium-Range Weather Forecasts (ECMWF) ERA-Interim. .. _`http://www.emisk.org/emisk/`: http://www.emisk.org/emisk/ .. _`http://volkov.oce.orst.edu/tides/pers.html`: http://volkov.oce.orst.edu/tides/PerS.html .. _`http://icdc.cen.uni-hamburg.de/1/projekte/easy-init/easy-init-ocean.html?no_cache=1`: http://icdc.cen.uni-hamburg.de/1/projekte/easy-init/easy-init-ocean.html?no_cache=1 20200814 20200707
