What is pysteps?
Pysteps is an open-source and community-driven Python library for probabilistic precipitation nowcasting, i.e. short-term ensemble prediction systems.
The aim of pysteps is to serve two different needs. The first is to provide a modular and well-documented framework for researchers interested in developing new methods for nowcasting and stochastic space-time simulation of precipitation. The second aim is to offer a highly configurable and easily accessible platform for practitioners ranging from weather forecasters to hydrologists.
The pysteps library supports standard input/output file formats and implements several optical flow methods as well as advanced stochastic generators to produce ensemble nowcasts. In addition, it includes tools for visualizing and post-processing the nowcasts and methods for deterministic, probabilistic, and neighbourhood forecast verification.
Quick start
Use pysteps to compute and plot a radar extrapolation nowcast in Google Colab with this interactive notebook.
Installation
The recommended way to install pysteps is with conda from the conda-forge channel:
$ conda install -c conda-forge pysteps
More details can be found in the installation guide.
Usage
Have a look at the gallery of examples to get a good overview of what pysteps can do.
For a more detailed description of all the available methods, check the API reference page.
Example data
A set of example radar data is available in a separate repository: pysteps-data.
More information on how to download and install them is available here.
