Later this year, the U.S. is proposing to introduce Aviation products in IWXXM to meet the new requirement from the International Civilian Aviation Organization (ICAO). By November 2020, States are required by ICAO to provide IWXXM formatted aviation products in conjunction with the Traditional Alphanumeric Content (TAC). IWXXM products for aviation include eXtensible Markup Language (XML) based representations for products standardized in ICAO Annex 3 and World Meteorological Organization (WMO) No. 49, Vol II, to be used for machine-to-machine operational exchanges of meteorological information for use in aviation. NWS has extended the use of XML formatted data to other non-aviation operational NWS products (e.g., Common Alerting Protocol (CAP) messages). If approved, with appropriate user notification, NWS may extend the use of IWXXM/XML formatted data to other existing operational NWS products.
