Oceanographic forecast model (NEMO-Nordic) - 60 TIM real time

Description

DESCRIPTION The data set contains forecast data from the NEMO-Nordic forecasting model. The first file ends at +000H00M and then follows forecast files for each hour up to +060H00M. NEMO-Nordic 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. The input data used are the meteorological forecast model Arome and the forecast model from ECMWF, as well as river data from the hydrological model HYPE. Forecasts are made for e.g. 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 based on observations. 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 average for a few days back in time. It is calculated every hour based on the latest observations. DELIVERY In this service you can download files with real-time data via web service for a delivery fee. The files should be saved before further use. Send an email to kundtjanst@smhi.se to order. 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 degrees) is not included in the grid. PARAMETERS dslm - Water level DTKE - Dissipation of turbulence (turbulent kinetic energy) icec - Ice concentration icetk - Ice thickness s - Salt content t - Temperatur TKE - turbulence u - eastward current (3D field) ucur - current in the east direction on the surface uice - ice movement in an easterly direction v - northward current vcur - current in a northerly direction on the surface vice - ice movement in a northerly direction wcur_ge - upward current USE At SMHI, data from NEMO-Nordic is used for, among other things, water level warnings, ice forecasts and investigations. NEMO-Nordic data is also used as input to other models, one example is the oil spill model SeatrackWeb. External users use NEMO-Nordic as input to their own oceanographic models via the international BOOS collaboration. The Swedish Armed Forces and a couple of municipalities also use NEMO-Nordic data. FORMAT Data is delivered in GRIB format. Information to facilitate its use can be found at: https://www.smhi.se/data/oppna-data/grib-format-1.30761
