Meteorological model (MEPS) - Real-time forecast data
Description
DESCRIPTION: The data files contain analysis and forecast data from the forecasting model MEPS. MEPS is an ensemble forecasting system with a total of 15 members over a three-hour period. This means that MEPS produces 15 different forecasts for each forecast occasion where the different members have equal initial states based on boundary values from selected ensemble perturbation from the European Weather Centre model. By using the information in all ensemble members, different probabilities can be calculated, e.g. how uncertain the forecast is. If you are only interested in a deterministic forecast, MEPS member 0 is used. Each model member runs every 3 hours with forecasts 66 hours ahead of time for the member. All mid-March data is generated in grib2 format, where only a limited number of parameters are retrieved from the members for each time they are generated. For member 0 and 1 all parameters are retrieved in grib1 format for every six hours, 00, 06, 12 and 18 UTC.
The forecast is made over an area covering Scandinavia, Finland, Denmark, the Baltics, the North Sea and parts of north-eastern Europe. The area is divided into grid squares with 2.5km resolution and 65 vertical levels. There are a large number of parameters that describe temperature, precipitation, wind, humidity, cloudiness, etc.
Use: At SMHI, data from MEPS is used as a basis for weather forecasts and as input to other models in areas such as hydrology and oceanography.
FORMAT: The data is in GRIB format.
