NAME

       metar - A METAR downloader/decoder

SYNOPSIS

       metar [-dvh] stations

DESCRIPTION

       METAR reports are meteorological weather reports for aviation. metar is a small program
       which downloads weather reports for user-specified stations and optionally decodes them
       into a human-readable format.

       Aviation weather stations are commonly referred to by ICAO designator. The ICAO is the
       International Civil Aviation Organization, a international standardization body for civil
       organization. For example, KJFK is the ICAO identifier for John F. Kennedy Airport in New
       York, New York, EHAM is the ICAO identifier for Amsterdam Schiphol Airport, The
       Netherlands, etc.

OPTIONS

       metar requires at least one station identifier to run. A full list of ICAO stations is
       available for download at http://weather.noaa.gov/data/nsd_bbsss.txt.

       metar supports three additional options:

       -d Decode the retrieved weather reports into a human-readable format.
       -v Be verbose while retrieving a report.
       -h Show a short help summary

ENVIRONMENT

       If the environment variable METARURL is set, metar will attempt to download the weather
       report from that location, rather than from the default (the NOAA web site). The value of
       METARURL will be postfixed with the capitalized station ID, followed by the .TXT
       extension.

       For example, if you have METAR reports in your home directory, setting METARURL to $HOME
       and asking for the weather report of ehgr will result in the file $HOME/EHGR.TXT to be
       read.
