Work Plans

Mandatory Functions

RWC Tokyo provides services covering the following mandatory RWC functions for WMO RA II Members.

  • Regional WIGOS metadata management (for work with data providers to facilitate collection, updating and provision of quality control for WIGOS metadata in OSCAR/Surface operation)
  • Regional WIGOS performance monitoring and incident management (WIGOS Data Quality Monitoring System, or WDQMS) and follow-up with data providers on availability/quality issues

RWC Tokyo

  1. Monitoring of availability, timing and quality of observation data provided by RA II Members using the WDQMS monitoring webtool
  2. Member encouragement for response to incidents and related handling via the Incident Management System for WDQMS (JIRA ECMWF)
  3. Provision of effective NMHS support via close collaboration with relevant WMO Centres run by JMA


RA II Members are categorized into Groups A and B for effective WDQMS implementation, with RWC Tokyo being responsible for each group in turn every six months. RWC Beijing (the other RWC in the region) covers the other group.

  • Group A (17 Members): From 1 January to 30 June, RWC Tokyo manages:
