Meteorological Analysis Model MESAN – API
Description
DESCRIPTION:
This service provides real-time analysis data from the MESAN analysis model. This meteorological analysis model describes the current weather situation for grid squares covering Sweden. Every hour of the day, a two-dimensional survey of common CEO 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.
DELIVERY:
Mesan data can be obtained via two different questions against an API.
One question provides MESAN data for one point at a time. In the link, you can specify any latitude and longitude within the geographical area, see coordinates.
The API returns data from the nearest grid point in this area. An example of calls with selected coordinates is:

For more information on how to use the Services, see: https://opendata.smhi.se/apidocs/metanalys/
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 squares are about 2.5 x 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 JSON format, see user guide above.
