GEPS

Global Ensemble Prediction System Forecast Dataset:

• GEPS 2-Week Forecasts
• GEPS 4-Week Forecasts

Description: The Global Ensemble Prediction System (GEPS) carries out physics calculations to arrive at probabilistic predictions of atmospheric elements from the current day out to 16 days into the future (up to 32 days once a week on Thursdays at 00UTC). The GEPS produces different outlooks (scenarios) to estimate the forecast uncertainties due the nonlinear (chaotic) behaviour of the atmosphere. The probabilistic predictions are based on an ensemble of 20 scenarios that differ in their initial conditions, choice of physics parametrization as well as stochastic perturbations (physical tendencies and kinetic energy). A control member that is not perturbed is also available.
