Build Status

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:
