v1.1.0
d402d82

Amendment 79 to Annex 3 is effective on 5 November 2020.

Changes to Annex 3 products, that are in IWXXM, are as follows:

  • Removal of the state of the runway from METAR reports. The metarDecoder.py will still recognize and process the runway state code, it just won't be encoded into IWXXM. In the near future, this capability will be removed from the metarDecoder.py as well
  • Introduction of a new mandatory element in the Tropical Cyclone Advisory (TCA): Intensity change. The decoder now expects this line to appear in the traditional alphanumeric code form of the TCA. This new element will appear in IWXXM when v3.1 is released which is planned for Spring 2021.
  • Wording changes introduced into the Volcanic Ash Advisory to indicate re-suspended ash.
