This folder contains 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 Insitute, Norwegian Meteorological institute
and Finnish Meteorological Institute.
