avwx
Fetch and parse aviation weather reports.
Currently, only standard METAR reports are supported, subject to extensive
testing. RMK sections are not yet supported. Making this parser work with all METARs is pretty tedious and difficult,
because every country seems to be using some subtly different specification.
This parser was written with the publicly available documentation from
DWD (Deutscher Wetterdienst) in mind, so it should work with all German
METARs. Patches (pull requests) and suggestions are very welcome!
Important: “For educational purposes only, not for flight planning! Use at
your own risk.”
Usage
This package is intended to be used as a library. However, for demonstration purposes,
it comes with a small command line utility that can be invoked like this:
hc@hc-pc ~ λ metar eddf llbg eham tncm
The output will look like this:
