Use Your Own Raw Data

metar_string = "KHWD 280554Z AUTO 29007KT 10SM OVC008 14/12 A3002 RMK AO2 SLP176 T01390117 10211\n"

Changelog

1.0.0

This version introduces a major change to the Metar::Raw class.

Previously, this class downloaded METAR data from the NOAA FTP site. The old functionality has been moved to Metar::Raw::Noaa. The new class, Metar::Raw::Data accepts a METAR string as a parameter - allowing the user to parse METAR strings without necessarily contacting the NOAA.

Alternative Software

Ruby

Other Ruby libraries offering METAR parsing:

• ruby-metar
• ruby-wx

There are many reports (WMO) that these libraries do not parse.

There are two gems which read the National Oceanic and Atmospheric Association's XML weather data feeds:

• noaa
• noaa-weather
