| title | CMA GRAPES GEPS v1.3 |
| description | The CMA-GEPS carries out physics calculations to arrive at probabilistic predictions of atmospheric elements from the current day out to 15 days. The probabilistic predictions are based on an ensemble of 30 perturbed members that differ in their initial conditions with Singular Vectors (SVs), their model uncertainties which are randomly perturbed by Stochastic Physics Perturbation Tendency (SPPT) method, and the Stochastic Kinetic Energy Backscatter (SKEB). Weather elements include temperature, precipitation, wind speed, gust and others. Data is available on a global latitude-longitude uniform grid with 0.25 degree horizontal resolution.Predictions are performed twice a day and initial conditions are at 00 UTC and 12 UTC. |
