Develop Volcano Observatory Notice for Aviation (VONA) by State Volcano Observatories (SVO)

amilan17 commented 1 year ago

Initial request

Recommendation 7/1 — VONA Introduction, VAA and Aerodrome Warning Template Improvements That the METP; b) request the WMO to develop appropriate headers and priorities for VONA in both TAC and IWXXM format, noting the request by the WG-MOG/IAVW work stream for the highest priority to be assigned; c) task WG-MIE to develop the IWXXM schema necessary for digital dissemination of the VONA; [source METP_5.Final Report.pdf, 2021 June]

See the extracted Template for Volcano Observatory Notice to Aviation (VONA) from the proposed text in working paper METP/5-WP/4102.

Other requirements mentioned in METP/5-WP/4102 include:

(PANS-MET/Para. 6.1.6) VONA shall be in abbreviated plain language, using approved ICAO abbreviations and numerical values of self-explanatory nature, and shall be in accordance with the template shown in Appendix 7, Table A7-1. When no approved ICAO abbreviations are available, English plain language text, kept to a minimum, shall be used to describe elements for which the template allows the use of free text.

(PANS-MET/Para 6.1.8) Only the following aviation colour codes shall be reported in the VONA:

GREEN — the volcano is in a normal, non-eruptive state; or, volcanic activity is considered to have ceased, and the volcano has reverted to its normal, non-eruptive state;
YELLOW — the volcano is experiencing signs of elevated unrest above known background levels; or, volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase;
ORANGE — the volcano is exhibiting heightened unrest with increased likelihood of an eruption; or a volcanic eruption is underway but with no or minor volcanic ash emission;
RED — a volcanic eruption is expected to be imminent with significant emission of volcanic ash into the atmosphere likely; or, a volcanic eruption is underway with significant emission of volcanic ash into the atmosphere; and
UNASSIGNED — there is insufficient information available to assess the current status of the volcano or volcanic activity.

Note.— The aviation colour code applies only to current volcanic activity associated with a volcano and does not apply to re-suspended volcanic ash

(PANS-MET/Para. 6.1.9) ... Further information on VONA is included in the Handbook on the International Airways Volcano Watch (IAVW) - Operational Procedures and Contact List (Doc 9766).

See Example A7-1.

New products and changes to existing schemas should originate in the iwxxm-modelling repository, yes?

amilan17 commented 1 year ago

Are you suggesting that I move this type of issue to the modelling repo?

mgoberfield commented 1 year ago

Hi @amilan17! Yes. Or at least, open a new issue in the iwxxm-modelling branch paralleling this one since its a new product. Prior instances of a new IWXXM product, the UML model is developed first and the resulting schema originates from EA.

Summary of changes:

Creation of a new WxObject "Volcano"
- In view of possible future reuse (e.g. QVA) it is grouped under the Meteorological Feature Package. It is, however, not suitable to replace metce:Volcano because of the additional metadata characterizing a WxObject.
- The following are definitiions of the WxObject:
  - iwxxm:issueTime: Issue time of the WxObject
  - iwxxm:originatingCentre: Type aixm:Unit is used to represent the identification of the centre publishing the WxObject
  - iwxxm:phenomenonBaseTime: Shall not exist
  - iwxxm:phenomenonCategory: Proposed new entry in WMOCategoryCode - volcanicObservations
  - iwxxm:phenomenonTime: Time when the phenomenon is observed
  - iwxxm:phenomenon: https://codes.wmo.int/49-2/MeteorologicalFeature/VOLCANO
  - iwxxm:phenomenonGeometry: Type gml:Point is used to represent the location of the volcano
  - iwxxm:phenomenonProperty: Type iwxxm:Volcano is used to represent the properties of the volcano, including:
    - iwxxm:name: Name of the volcano
    - iwxxm:IAVCEINumber: IAVCEI number of the volcano
    - iwxxm:sourceElevation: Elevation of the vent of the volcano from MSL
    - iwxxm:activityStatus: Current activity status of the volcano
    - iwxxm:lastVolcanicAshEmission: Time of last volcanic ash emission
    - iwxxm:onsetTime: Time of onset of eruptive activity
Creation of a new WxObject "ResuspendedVolcanicAsh"
- Created under the Volcano Observatory Notice For Aviation Package
- The following are definitions of the WxObject:
  - iwxxm:issueTime: Issue time of the WxObject
  - iwxxm:originatingCentre: Type aixm:Unit is used to represent the identification of the centre publishing the WxObject
  - iwxxm:phenomenonBaseTime: Shall not exist
  - iwxxm:phenomenonCategory: Proposed new entry in WMOCategoryCode - volcanicObservations
  - iwxxm:phenomenonTime: Time when the phenomenon is observed
  - iwxxm:phenomenon: Proposed new entry in code list - https://codes.wmo.int/49-2/MeteorologicalFeature/VOLCANIC_ASH
  - iwxxm:phenomenonGeometry: Type gml:LinearRing is used to represent the location of the re-suspended ash
  - iwxxm:phenomenonProperty: Type iwxxm:ResuspendedVolcanicAsh is used to represent the properties of the re-suspended volcanic ash, including:
    - iwxxm:height: Average height of re-suspended volcanic ash field
Creation of a new WxObject "VolcanicAshCloudVerticalExtent"
- Created under the Volcano Observatory Notice for Aviation Package
- The following are definitions of the WxObject:
  - iwxxm:issueTime: Issue time of the WxObject
  - iwxxm:originatingCentre: Type aixm:Unit is used to represent the identification of the centre publishing the WxObject
  - iwxxm:phenomenonBaseTime: Shall not exist
  - iwxxm:phenomenonCategory: Proposed new entry in WMOCategoryCode - volcanicObservations
  - iwxxm:phenomenonTime: Time when the phenomenon is observed
  - iwxxm:phenomenon: Proposed new entry in code list - https://codes.wmo.int/49-2/MeteorologicalFeature/VOLCANIC_ASH
  - iwxxm:phenomenonGeometry: Type iwxxm:ElevatedLevel is used to represent the height of the volcanic ash cloud
  - iwxxm:phenomenonProperty: Type iwxxm:VolcanicAshCloudVerticalExtent is used to represent the properties of the volcanic ash cloud, including:
    - iwxxm:heightSource: Source of height data
    - iwxxm:movement: Direction of movement of the observed cloud
      1. Creation of a new WxObject collection "VolcanoObservatoryNoticeForAviation"
- The following are definitions of the WxObject collection:
  - iwxxm:boundingPeriod: Shall be the same as iwxxm:PhenomenonTime
  - iwxxm:boundingVolume: TBD
  - iwxxm:phenomenaList: Shall be https://codes.wmo.int/49-2/MeteorologicalFeature/VOLCANO and https://codes.wmo.int/49-2/MeteorologicalFeature/VOLCANIC_ASH
  - iwxxm:issueTime: Issue time of the WxObject collection
  - iwxxm:originatingCentre: Type aixm:Unit is used to represent the identification of the SVO publishing the WxObject collection on VONA
  - iwxxm:phenomenonCategory: Proposed new entry in WMOCategoryCode - volcanicObservations
  - iwxxm:phenomenonBaseTime: Shall not exist
  - iwxxm:phenomenonTime: Time when the phenomenon is observed
  - iwxxm:feature:
    - Shall include either one of Volcano or Re-suspended Volcanic Ash WxObject as the source term
    - Shall include one of Volcanic Ash Cloud Vertical Extent WxObject as the resulting ash cloud term
  - iwxxm:stateOrRegion: State or region involved
  - iwxxm:noticeNumber: VONA Notice Number
  - iwxxm:currentColourCode: Current aviation colour code
  - iwxxm:previousColourCode: Previous aviation colour code
  - iwxxm:contacts: SVO contact details
  - iwxxm:remarks: Remarks
  - iwxxm:nextNotice: Indication of the issuance of next VONA
