In this post, I’m gonna provide an introductory tutorial for fitting an extreme value distribution via Bayesian analysis with Stan and its R interface, rstan. Stan is a probabilistic programming language written in C++ suitable for Bayesian inference and rstan is a package providing access to Stan thru R. More about Stan can be found […]

For that, I am using re-analysis rainfall data from the Irish Meteorological Service. In the video below, you can take a look inside a flood forecasting and early warning system. It […]

Lately, I have been searching for Python modules that can help me work easily and effectively with ensemble forecasts data. And by “work”, I mean read and visualize ensembles in a proper way, as well as extract useful information e.g. what is the probability of streamflow being over a threshold on a specific day? Apparently, after […]
