pysteps 0.1 is our first stable release. This beta version is being verified using radar data from the Finnish Meteorological Institute and MeteoSwiss.

Features included in pysteps 0.1:

  • Support for reading various composite radar image formats (netCDF, OPERA HDF, GIF, PGM).
  • Writing of the nowcast to netCDF following CF 1.7 conventions.
  • Optical flow methods to compute the radar echo motion fields (local and spectral approaches are available).
  • A semi-Lagrangian advection scheme to extrapolate the radar fields.
  • Spatial random field generators to create realistic correlated perturbation fields.
  • Autoregressive models to impose temporal auto-correlations.
  • Methods to generate deterministic and ensemble precipitation nowcasts.
  • Support for parallelization using Dask.
  • Scale-decomposition of precipitation fields based on the STEPS framework.
  • Verification of deterministic and spatial forecasts: RMSE, MAE, correlation, CSI, ETS, HSS, Fractions Skill Score, etc.
  • Verification of ensemble and probabilistic forecasts: reliability diagram, rank histograms, ROC curves, CRPS, ensemble spread-skill.
  • Utilities to convert, transform and aggregate precipitation fields.
  • Visualization methods to plot and animate radar rainfall fields, motion fields and ensemble nowcasts. Support for Basemap.
  • Example scripts to quickly introduce the users to the working of various modules.
