wradlib example data

This repository contains example data used by notebooks/examples from wradlib/wradlib.

We've moved the repository to use pooch for downloading and caching wradlib-data files locally. Please adapt your workflows.

• Ensure the wradlib_data package is installed in your environment

  $ python -m pip install wradlib-data
  
  # or
  
  $ python -m pip install git+https://github.com/wradlib/wradlib-data@pooch

• Import DATASETS and inspect the registry to find out which datasets are available

  In [1]: from wradlib_data import DATASETS
  
  In [2]: DATASETS.registry_files
  Out[2]: 
  ['dx/raa00-dx_10908-0806021655-fbg---bin.gz',
  ...
  'trmm/2A-RW-BRS.TRMM.PR.2A25.20100206-S111422-E111519.069662.7.HDF']  

• To fetch a data file of interest, use the .fetch method and provide the filename of the data file. This will

  • download and cache the file if it doesn't exist already.
  • retrieve and return the local path.

    In [1]: from wradlib_data import DATASETS
    
    In [2]: filepath = DATASETS.fetch("furuno/0080_20210730_160000_01_02.scn.gz")
    Out[2]: 
    Downloading file 'dx/raa00-dx_10908-0806021655-fbg---bin.gz' from 'https://github.com/wradlib/wradlib-data/raw/main/data/dx/raa00-dx_10908-0806021655-fbg---bin.gz' to '/user/kmuehlbauer/.cache/wradlib-data'.

• The datasets will be retrieved to your standard system cache-folder. To specify the location please set WRADLIB_DATA environment variable to the wanted path.

  • Linux:

    $ export WRADLIB_DATA=/path/to/wradlib-data

  • Windows:

    set WRADLIB_DATA C:\path\to\wradlib-data
    
    # or
    
    setx WRADLIB_DATA C:\path\to\wradlib-data

The provided data is used in wradlib notebooks and examples.
