METP and WG-MIE

WG-MIE proposes decisions and actions to the MET Panel – WG-MIE decisions may not necessarily be adopted by METP or the ANC

SARPS Timing and effective dates

An 18-month lead time would be more suitable for all changes (TAC and IWXXM) relating to Annex 3 for realistic implementation schedules

It was agreed in WG-MIE that applicability dates should therefore be at least 18 months after each Annex 3 Amendment is published

Permissible Usage

• All IWXXM messages should contain an indicator permissibleUsage that will be set to one of two possible values:

– 'OPERATIONAL' or ‘NON-OPERATIONAL’

• Optional permissibleUsageReason may be included that will be set to 'TEST' or ‘EXERCISE’.

• Optional permissibleUsageSupplementary may be included to specify details such as the exercise name.

Permissable Usage (2)

ROC Validation

• ROCs/RODBs to validate all IWXXM messages within their AOR

– Invalid IWXXM messages are not rejected

– Statistics are captured

– Suggested statistics include at least daily and monthly averages for valid messages, broken down by State and Region

Translation Centres

• Translation from TAC to IWXXM (conversion) may be performed by the originating State, or by formal agreement with another State or Region

• Thought should be given to how State-specific registered differences will be handled

Translation Centre metadata

• Translation centres should record metadata in generated IWXXM messages

Translation Errors

When translation errors are encountered the IWXXM message includes only message type (e.g., METAR) and original TAC Can happen in (at least) two scenarios: • Incomplete translation (not all elements

translated) • Errors are encountered while translating

Policy will be reviewed and refined over time by MIE

AMHS

• Extended AMHS identified for IWXXM dissemination

• Mixed AMHS implementation among States and Regions

• Compression support may be a challenge (e.g., GZIP)

• Large messages may be a challenge

MET-SWIM Plan

Work in progress by MIE, draft delivered to METP by August 2016 • Multiple data types: gridded, non-gridded,

imagery • Standardized web services/SOA infrastructure

identified for each data type • Relies upon HTTP and AMQP support (atop

general IP infrastructure) • Will utilize the SWIM Registry for data and web

service discovery metadata

MET-SWIM Roadmap

A roadmap will be developed that identifies:

• ASBUs identified for MET-SWIM implementation

• ASBUs identified for dependencies (CP and IMP components)

• A significant period for system transition where current and future capabilities are both available (likely)

Information Management Panel (IMP)

Broad group tasked with information management topics across MET, AIM, and other domains in SWIM

MIE and the IMP Governance Working Group share a few members

Recent topics have related to governance, but much broader than MET-related governance
