 The subseasonal forecast is based on 3  weather prediction models:
 
-1. The MetCoOp Ensemble Prediction System [MEPS](https://doi.org/10.1002/qj.3525). MetCoOp is the Meteorological Cooperation on Operational Numeric Weather Prediction (NWP) between Finnish Meteorological 
-   Institute (FMI), MET Norway, Swedish Meteorological and Hydrological Institute (SMHI) and Estonian Weather Service. It provides short term forecasts (0 - 60 hours) and has a horizontal resolution of 2.5 kilometers. Forecasts are updated every hour. 
-2. The atmospheric model Ensemble 15-day forecast from [ECMWF](https://www.ecmwf.int/en/forecasts/datasets/set-iii. Forecasts are updated twice pr day. Horizontal resolution is approximately 10 km.  These forecasts are used for days 3 - 15.
