AMOFSG Ad Hoc Working Group
Terms of Reference
|
1. Tasks
|
|
The WG is tasked to prepare a first draft of operational service needs and corresponding deliverables for the MSTA by looking at the following questions:
|
- Weather parametersWhat currently existing parameters need to be predicted? Are there new parameters (e.g. thunderstorm density?) that need to be considered?
- Spatial and temporal scalesWhat time scales and lead times are appropriate? How will the spatial variability within the wider terminal area as proposed by the WMO CAeM ET-MSTA be addressed? Is there a need for reviewing this space scale over time?
- Applicable locationsThe WG may suggest a "minimum traffic" criterion for locations requiring the additional products, data and service, possibly "staged" from a basic set to a fully-blown range of products. Topographic considerations (e.g. Hong Kong, China; Bhutan etc) may enter these definitions as additional drivers.
- Desirable accuracy and resolutionThere will be a need to refine desired accuracies for QMS purposes.

2. Work Plan and modus operandi
|
|
The WG is tasked to develop a prototype plan (and schedule), with reference to the ICAO Annex 3 amendment cycle, for consideration during and after AMOFSG/8. The prototype plan (and schedule) should include efforts of evaluation, e.g. based on user's feedback on prototypes available on the MSTA web-based platform (http://www.ntf.weather.gov.hk) and development of guidance material and training for users to facilitiate and future implementation of the MSTA products.
|
|
It is expected that the group will perform most of the work by correspondence but will meet at every subsequent AMOFSG meetings.
|
|
The WG can invite other industry experts to meetings (in person or virtual at their own expense)
|
|
The WG will provide status updates, as necessary, to the AMOFSG.
