A one hour tour of wradlib#
A guided tour of some \(\omega radlib\) notebooks.
(find all wradlib notebooks in the Tutorials & Examples.)
Some background, first#
Development started in 2011…or more precisely:
October 26th, 2011
A community platform for collaborative development of algorithms

1. Install Anaconda or Miniconda#
2. Create environment, add conda-forge, install wradlib#

Reading and viewing data#
Read and quick-view#
Let’s see how we can read and quick-view a radar scan.
Zoo of file formats#
This notebook shows you how to access various file formats.
Addressing observational errors and artefacts#
In this example, we reconstruct path-integrated attenuation from single-pol data of the German Weather Service.
wradlib provides several methods for clutter detection. Here, we look at an example that uses dual-pol moments and a simple fuzzy classification.
Partial beam blockage#
In this example, wradlib attempts to quantify terrain-induced beam blockage from a DEM.
Integration with other geodata#
Average precipitation over your river catchment#
In this example, we compute zonal statistics over polygons imported in a shapefile.
Over and underlay of other geodata#
Often, you need to present your radar data in context with other geodata (DEM, rivers, gauges, catchments, …).
Merging with other sensors#
Adjusting radar-based rainfall estimates by rain gauges#
In this example, we use synthetic radar and rain gauge observations and confront them with different adjustment techniques.
