Meteorological model (AROME) - soil parameters

Description

DESCRIPTION This data set contains ground parameters for real-time analysis and forecast data from the last two runs of the forecasting model AROME. The files XAM25H2_* contain postprocessed so-called ground fields that are specified for a certain height above ground. The model runs 00, 06, 12 and 18 UTC. The first file is the analysis file and then follows 60 forecast files, one for each time step. AROME is a numerical forecasting model that describes the weather's development in time and space. The model has been developed in international cooperation involving a large number of European countries. The forecast is based on what the weather looks like at a certain time, the so-called initial state. To map this, an analysis of the weather situation is made. In doing so, an earlier forecast is modified to be more consistent with current observations. This is done using a variable method. Thus, the value of the various forecast parameters can be determined in a grid. In the model, these squares are currently 2.5 x 2.5 km in horizontal extent and the atmosphere has been divided into 65 levels in the vertical direction. Eight forecasts are made per day, but only four (runs made at the main semesters 00, 06, 12 and 18UTC) are used for forecasting purposes. The others are only used for updating the analysis to the next main semester run. Each main semester forecast extends up to just under 3 days in the future. Every 3 hours during the day, a three-dimensional survey of different weather parameters is made. The mapping is done to determine conditions in the soil but not least to describe what it looks like in the atmosphere. This can include temperature, humidity, wind, air pressure, cloudiness and precipitation, but also, for example, radiation conditions, the extent of sea ice or the water content of snow. All of this has a bearing on the development of the weather. The AROME analysis is made over an area covering Scandinavia, the northern part of the continent and the Baltic States. 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 Coordinates for the area are given by the corners Southwest 52.04N, 1.64W Northwest 72.30N, 12.65W Northeast 72.30N, 42.73E Southeast 52.04N, 28.38E The grid squares are 2.5 x 2.5 km USE At SMHI, AROME is used as a basis for forecasts in radio and television. It is also used for forecasting to commercial customers such as various newspapers and municipalities. Data from AROME can also be used as input to other models. This applies to meteorological, hydrological and oceanographic FORMAT Data is delivered in GRIB format.
