MarsSeed [1] filed a deletion request for python-wradlib [2]: Seems there is no interest in maintaining this orphan Python module on AUR related meteorological science.
It was uploaded a year ago and never updated. It is also outdated and has a packaging issue. Those who need this are better served by other platforms that host this, e.g. PyPI or Anaconda. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python-wradlib/
