The following table shows the amendment number to ICAO Annex 3 against the WMO approved IWXXM versions of individual package (e.g. METAR/SPECI) that shall be use for information exchange. If more than one version are indicated for an IWXXM report, it means the information model of the report has not been changed across the versions and either one of them can be used.
| ICAO Annex 3 | METAR/SPECI | TAF | SIGMET | AIRMET | Tropical Cyclone Advisory | Volcanic Ash Advisory | Space Weather Advisory |
|---|---|---|---|---|---|---|---|
| Amendment 76 | 1.1 | 1.1 | 1.1 | N/A | N/A | N/A | N/A |
| Amendment 77 | 2.1 | 2.1 | 2.1 | 2.1 | 2.1 | 2.1 | N/A |
| Amendment 78 | 3.0 | 3.0 | 3.0 | 3.0 | 3.0 | 3.0 | 3.0 |
Please note that patch numbers are not included in this table as the information model of any of the IWXXM packages is not supposed to be changed in a patch. See the Version Policy for more information.
