SE.OF Oceanographic forecast model, NEMO-Nordic - Historical analysis data

Description

DESCRIPTION The data set contains historical model data from the forecasting model NEMO-Nordic. This means that only data for the first time step has been selected. Forecast data are not included. NEMO-Nordic NS01 is an oceanographic forecast model that describes the state of the ocean for a number of physical parameters. Every 6 hours, a 60-hour forecast is run based on data assimilation of available observations. Until March 2017, the HIRLAM meteorological forecast model (C11) was used as input data, followed by the Arome meteorological forecast model and the ECMWF forecast model, as well as river data from the HYPE hydrological model. Forecasts are made for e.g. water temperature, salinity, currents, water levels and ice. The area covered by NEMO-Nordic is the entire Baltic Sea, the west coast of Sweden (Kattegat and Skagerrak), the North Sea and the English Channel. When using water level data, the data shall be offset corrected as the zero level of the model is not the same as the water level of the area. Offset correction is made based on observations for the current time period. The correction shall be carried out on a rolling basis for each station, as they have different reference levels. One method of offset correction is to use a running mean sea level for a few days back in time. Coordinates The coordinates of the area are given by the corners: lat: lon: -4.1 lat: lon: -4.1 lat: lon: 30.2 lat: lon: 30.2 The grid squares are 1 nautical mile (about 2*2 km). Please note that the area north of the North Sea (about 59.3) is not included in the grid. USE At SMHI, data from NEMO-Nordic is used for water level warnings, ice forecasts and various investigations. NEMO-Nordic data is also used as input to other models. One example is the SeatrackWeb oil spill model. NEMO-Nordic is also used as input to other oceanographic models via the international BOOS collaboration. FORMAT Data is delivered in GRIB format.
