  • FIX: properly implement bearer token authentication adn function calling convention for plot_scan_strategy with terrain=True (GH651) by @JulianGiles, (PR652) by @kmuehlbauer

  • FIX: align earth radius in plot_scan_strategy for CG plots (PR655) by @kmuehlbauer

  • FIX: new default value for crs in cross_section_ppi is “None”: crs = kwargs.get(“crs”, “None”). This fixes an issue with the altitude value of the georeferenced object. By @JulianGiles

Version 2.0.0#

For \(\omega radlib\) 2.0.0 there have been quite some deprecations and additions. Most of the changes have been announced over the latest \(\omega radlib\) 1 versions. Nevertheless, to make a clean cut it was neccessary to change and remove code and functionality which was not yet being officially deprecated.

Please follow up at wradlib 2.0 migration.

The major new feature is the smooth integration into xradar-based reading into xarray-based data structures and the convenient use of xarray-accessors. The tutorials and examples got a major overhaul to show the capabilities of \(\omega radlib\) in the light of these new developments.

This version also brings doc-folder back into wradlib repo. The wradlib-docs repo will be archived. wradlib-notebooks repo has been restructured as well, with a single point of access.

Bugfixes

  • fix RADOLAN xarray ‘prediction_time’ for RADVOR datasets (PR639) by @Hoffmann77

Version 1.19.0#

This version is most likely the last version before wradlib 2.0. We’ve switched to use xradar for reading radar data in polar coordinates. The relevant code has been ported from wradlib to xradar and only a shallow compatibility layer is kept in wradlib.
