NWP forecasts produced with MEPS ((MetCoOp Ensemble Prediction System )model 
(cycle 40h1.2 2018-10-1 00Z - 2019-03-31 18Z, cycle 40h.1.2 2019-10-1 00Z - 2021-03-23 06Z,
cycle 43h2.1.1 2021-03-23 12Z - 2021-03-31 18Z). Only the control run is included.
Model runs are done as part of MetCoOp (Meteorological Co-operation on Operational Numerical Weather Prediction)
cooperation between Swedish Meteorological and Hydrological Institute, Norwegian Meteorological institute
and Finnish Meteorological Institute.

In case of forecasts for 5 Oct 2018 - 26 Jan 2020, there were two stations
where the interpolation point of the MEPS data was somewhat off:
106868 Huittinen Korvenmaa 61.110260 22.653020 (about 10 km from the point in coordinates.txt)
106908 Ranua Portimo 66.157150 26.247130 (about 6 km from the point in coordinates.txt)


Each file contains forecasts for one month. For January 2021 there are two files because
the data format changes at 19th January. Different forecasts are separated in the file by:
