DayCast™ is a weather forecasting technique developed by Reuniwatt, and specifically optimised for the day-ahead and up to a whole week aheadcloudiness and solar irradiance.
DayCast™ combines several numerical meteorological models, permitting to improve the forecasts’ robustness. Artificial intelligence techniques train our models to better take local phenomena into account.
DayCast™ offers a global coverage and offers many parameters useful for the next day’s forecasts:
- Simulation thanks to a weather model integrating regional specificities
- External weather data integration so as to improve the model’s pertinence
- Frequent updates of the simulations
- Initialisation of high-resolution cloud resolving regional models using innovative data assimilation methods
