This go program fetch the aviation METAR's and TAF's for a given list of airports in console (terminal) mode. Special care has been put into execution speed using the goroutines for simultaneous data retrieval of METAR's and TAF's.

As an addition to the METAR messages, Wind Chill factor, Heat Factor and Relative Humidity are computed when applicable.

##Usage

Retrieve messages for a list of stations (IATA or ICAO codes):

$ metar lhr jfk bru uudd

The output looks like this:

UUDD (DME) Moscow (Domododevo), Russia
UUDD 301700Z 22004MPS 9000 -SHRA BKN014CB 15/12 Q1007 R14R/290095 R14L/290094 NOSIG [15 15 82%]

At the end of the METAR's, the three values between brackets are the computed [ wind chill factor | heat factor | relative humidity % ]

Find the IATA/ICAO airport code for an airport

$ metar -s munich
$ metar -s "new york"

Options

-r    raw output (no airport header and no additional factors)
-n N  number of metar to print (min. 1, max. 10)

Example: $ metar -r -n 5 bru jfk prints the latest 5 metars in raw format

Help screen:

$ metar -h

You will have to compile the sources using the golang tools. Follow this howto to get you started. The compilation is lightning fast and the cross-compilation easy.

You can also use the binaries that I have cross-compiled for your convenience.

Linux and Mac users will have to make that file executable: $ chmod +x metar

To run it (Linux and Mac): $ ./metar

Rough edges are not excluded. Please report any bugs.
