Welcome to RainyDay! RainyDay is an open source framework for generating large numbers of realistic extreme rainfall scenarios based on remotely-sensed precipitation fields. It is founded on a statistical resampling concept known as stochastic storm transposition (SST). These rainfall scenarios can then be used to examine the extreme rainfall statistics for a user-specified region, or to drive a hazard model (usually a hydrologic model).
RainyDay is written in Python 3 and is available in Github. We highly recommend reading the related publications and the RainyDay User’s Guide (found here) and examining the example files available on Github.
