Pre-release
Pre-release
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.
