metaf2xml Logo metaf2xml: parse and decode METAR, TAF, SYNOP, BUOY and AMDAR and write data as XML
(deutsche Version, versión española)

metaf2xml can download, parse and decode aviation routine weather reports (METAR, SPECI, SAO), aerodrome forecasts (TAF), synoptic observations (SYNOP), observations from buoys (BUOY) and meteorological reports from aircrafts (AMDAR). Data can also be taken from decoded BUFR messages. The extracted data can be written as XML or passed to a user-defined function (all done in Perl).

It also provides XSLT style sheets to convert the XML to plain language (text, HTML), or XML with different schemas. A web-based (CGI) user interface can be used to download and display up-to-date weather data from NOAA, Ogimet, and other sources.

Background

METAR and SPECI (weather observation) and TAF (weather forecast) information is essential for flight planning and in-flight decisions (real flight and simulation). It is regularily compiled by meteorologists for more than 6200 airports worldwide and distributed via reliable, non-public networks. SYNOP information is collected by more than 7600 manned and unmanned meteorological stations and more than 2500 mobile stations around the world and is used for weather forecasting and climatic statistics. The format of the original messages is abbreviated, some items are coded.

Here are some METAR, TAF, and SYNOP messages from Rio (SBGL, 83746), New York (KJFK, 74486), and Tokyo (RJTT, 47662) and messages from nearby buoys (as alphanumeric (TAC) and decoded from BUFR):

The format of the messages (and a lot more about observing and reporting weather) is specified in WMO Manual No. 306 or in Annex 3 to the Convention on International Civil Aviation; some countries deviate from that standard or extend it, some have published documentation (e.g. Federal Meteorological Handbook No. 1 and No. 2 for the USA). Especially the format of the remarks for METAR and TAF messages, or the coding of sections 3 and 5 for SYNOP messages depend on the country or even the observing station.

metaf2xml can be used for flight simulations or by private pilot (students) who want to extend their knowledge about the message formats, and everyone who just wants to know the current or forecast weather at some station in plain language (see examples below).

Why another METAR/TAF parser?

There are other projects that deal with METAR and TAF messages, e.g.:

But somehow I always missed a feature I liked to have.

Features of metaf2xml

processing of messages

The parser module (man page) accepts (= processes) or tolerates (= marks as error) many extensions to the standard; they are marked with "EXTENSION" in the source code. Many common minor errors in the format are corrected before parsing, more combinations of weather phenomenons are allowed, missing information is recognised in many cases, too.

All remarks are processed, some of them are interpreted depending on the issuing country or station, e.g. 'MON INVIS VAL FOSCHIA' and QUL/QUK (Italy), 'JP' (some carribean countries), 'YLO1' (military), everything from the Federal Meteorological Handbook No. 1 and the Air Force Manual 15-111 (19.12.2003), 'RSNK' and 'LAG PK' (data from other observing stations), and many more. Currently, more than 80 types of METAR remarks are recognised, excluding trivial keywords (see also the DTD).

This module can write the data as XML. Alternatively, a callback function can be registered which is passed step by step the same data in the same order as for the XML output.

The data contains solely information from the original message, with 2 exceptions: the relative humidity (actually 4 different values from 4 different formulas) and the ceiling (if there is one); these 2 items are cumbersome to compute with XSLT. For each data element, the corresponding text from the message is provided.

The intention is to gain as much information as possible from a message without interpreting parts of it wrongly, and that no parsing of the output data should be necessary.

source of messages

Messages can be specified simply as text. Additionally, the script metaf.pl (man page) can be used from the command line or as CGI script to download and display in plain language up-to-date weather data from Internet servers, an SQL database, or a local file.

metaf.pl uses the module src2raw.pm (man page) to extract correctly formatted messages from the files provided by public servers.

display of XML file

The project also provides XSLT style sheets to convert the XML to plain language as text or HTML in English, German, Spanish, and Russian. The output in the text format is similar to the one of the program "metar" from the FlightGear project. The HTML output displays each message in a separate table. The leftmost column contains the original text for each element of the message, the top row contains the original message (see also project screenshots or examples below). To convert the content to text or HTML, the program "xsltproc" is used, but others that work similar shouldn't be a problem.

There are also XSLT style sheets to create a summary or overview: only some items of each message are shown in an abbreviated format, one line per message.

command line interface

The script metaf2xml.pl (man page) reads messages, processes them, and writes the XML data to standard output. It can serve as input for "xsltproc" or similar programs to get HTML or text.

The script metaf.pl (man page) can be used to fetch up-to-date messages from other sources.

web interface

Ideally, any XML capable browser should be able to process the XML with the XSLT style sheet specified in the file, and display the formatted result, but not all browsers are XML capable. The script metaf.pl (man page) provides an interface using either XML/XSLT or pure HTML. The XML data can be seen by viewing the source of the web page if "XML" was selected as output format.

source code is available and GPL

Everybody who wants to contribute is invited to do so. The best starting point is the ticket system.

To try it out

The latest version of metaf2xml can by tried out at SourceForge. However, the demo version cannot provide up-to-date messages for stations, as SourceForge does not allow outgoing connections to the internet. The messages are fetched from a database on the SourceForge server instead. The database is updated from time to time, only.

With the demo version with graphics (uses Ajax), the stations are marked with a dot on a map. The map can be viewed in different enlargements and can be moved by click and drag. The requested messages are displayed beneath the map, the latest one on top. The list of stations is created dynamically from the same database.

With the text-based demo version, weather messages can be entered. If an option with "id(s)" is chosen, station id(s) can be entered, too.

Sources for weather data

Several organisations and providers offer public access to up-to-date and older weather data, e.g.:

Examples for messages in plain language

The result of the parsing of the above example messages can be found in example.xml (XML without XSLT style sheet reference). Using the XSLT style sheets from the project, the output in plain language (here: as HTML, summary first, detailed below) looks as follows:
