Probabilistic forecast
Estimating the likelihood of an event occurring enables better decision making by end users to reduce risk.
Learn more
Since uncertainty is an inherent ingredient in forecasting, our system optimally combines ensemble forecasts from different models to generate percentiles as well as custom confidence indices for each weather parameter and location in the world.

Numerical Weather Prediction
Frogcast aggregates data from over 20 different numerical weather prediction models operated by national meteorological agencies around the world.
We also use the Weather Research and Forecast (WRF) model on demand, especially in regions where high-resolution models are not publicly available and where atmospheric processes are complex to model. All these models are pre-processed in a similar way, taking into account their specificities.

Confidence intervals
Confidence intervals are an essential source of information in weather forecasting. In particular, they make it possible to objectively quantify the uncertainty associated with a forecast. Here we define confidence intervals, describe how they are generated and illustrate their possible uses.
