Meteorological analysis model MESAN (GRIDPP) – historical analysis data

DESCRIPTION
This dataset contains archived MESAN data up to and including the day before the withdrawal takes place.
Data are available as of February 2024. Prior to that, the corresponding data were supplied by MESAN (AROME) and MESAN (HIRLAM).
Mesan is a meteorological analysis model that describes the current weather situation in grid squares.
Every hour of the day, a two-dimensional survey of common weather parameters is performed. Who these are varies slightly over the day. Essentially, they describe meteorological conditions such as temperature, precipitation, clouds, visibility, humidity, wind and snow.
The analysis is carried out over an area covering Scandinavia, the northern part of the continent and the Baltic states.

COORDINATES
Coordinates of the area are given by the corners:
Southwest 52.30N, 2.15E
Northwest 70.39N, 8.32W
Northeast 70.44N, 37.50E
Southeast 52.33N, 27.21E

The grid windows are 2.5*2.5 km.

USE
Mesan data is used at SMHI to make weather maps that the meteorologist has as a basis for forecasting. If there are no observations, analysed values can sometimes replace them. Mesan data is also used as input to other models, e.g. to calculate runoff in our watercourses or to map the risk of fires in forests and soil.

FORMAT
Data is delivered in GRIB format. Information to facilitate use can be found at:
