IWXXM

ICAO Meteorological Information Exchange Model (IWXXM) is a format for reporting weather information in XML/GML. IWXXM includes XML/GML-based representations for products standardized in International Civil Aviation Organization (ICAO) Annex III, such as METAR/SPECI, TAF, SIGMET, AIRMET, Tropical Cyclone Advisory (TCA), Volcanic Ash Advisory (VAA), Space Weather Advisory and World Area Forecast System (WAFS) Significant Weather (SIGWX) Forecast. IWXXM products are used for operational exchanges of meteorological information for use in aviation.

History

IWXXM Version 1 was introduced in October 2013, representing METAR, SPECI, TAF and SIGMET formats as specified in International Civil Aviation Organization (ICAO) Annex III, Amendment 76. A new version of IWXXM is being developed in response to the proposed changes in the upcoming Amendment 81 to ICAO Annex 3. ==Regulation==

Regulation

IWXXM is regulated by WMO in association with ICAO. IWXXM is defined at the technical regulation level in WMO No.306 Volume I.3 to meet the regulatory requirements described in ICAO Annex III. Another document ICAO Doc 10003 is also available to provide a high level description of the model. ==Development==

Development

The WMO Commission for Observation, Infrastructures and Information Systems (INFCOM) Task Team on Aviation Data or TT-AvData (previously Commission for Basic System (CBS) Task Team on Aviation XML or TT-AvXML) and ICAO Meteorological Panel (METP) Working Group on Meteorological Information Exchange (WG-MIE) are involved in the development of IWXXM. The e-mail group was created to collect feedback from users. A GitHub repository has been created to engage community participation. ==Relationship with WXXM==

Relationship with WXXM

WXXM is governed by FAA and EUROCONTROL for international products outside of those represented by ICAO or WMO. WXXM 1.0 was released in 2007. There were no new releases since the publication of WXXM 3.0.0 in 2019. ==See also==
