Overall requirements and standards for RSMCs

The Outline refers to the Outline of the Operational Numerical Weather Prediction at the Japan Meteorological Agency, available at http://www.jma.go.jp/jma/jma-eng/jma-center/nwp/nwp-top.htm.

  1. Quality control of incoming observations
  2. RSMCs operated by JMA apply quality control to the incoming observations they use for GDPFS purposes, in accordance with the WIGOS quality assurance and quality control standards, and contribute to the Rolling Review of Requirements in the area of the observational requirements.

    Specifications of observation data quality control are described in 2.3 Quality Control and Relating Procedures of the Outline (2013 edition).

    RSMCs operated by JMA publish Quality Monitoring Reports at http://qc.kishou.go.jp/ monthly and biannually. JMA serves as the Lead Centre for quality monitoring of land surface observations in the area of Regional Association II.

  3. Data collection and product dissemination
  4. A Data Collection or Production Centre (DCPC) RSMC - Geographical serves as the interface to the WMO Information System for all the RSMCs operated by JMA. The DCPC is connected to Global Information System Centre (GISC) Tokyo and conduct suitable exchange of information with other Centres.

    All the products and services of RSMCs operated by JMA are described according to WMO metadata standards and the information is uploaded to WIS metadata catalogue in a timely manner.

  5. Long-term storage of data and products
  6. RSMCs operated by JMA operate an archiving and retrieval system to serve the needs of their continual improvement process, which include the non-real-time assessment of their products and the ability to perform re-runs of their operational production.

    Specifications of storage are described in 1.2.4 Mass Storage System of the Outline (2013 edition).

  7. Product verification / performance of GDPFS Centres
  8. Products of RSMCs operated by JMA the forecast are operationally monitored by objective verification procedures.

    Details of the verification procedures are described in 3.9 Verification of the Outline (2013 edition).

    RSMCs operated by JMA participate in various verification activities of GDPFS Centres, including those for deterministic numerical weather prediction (NWP), ensemble prediction system (EPS), long-range forecast (LRF), wave forecast and tropical cyclone forecast. JMA serves as the Lead Centres for coordination of EPS and tropical cyclone forecast verification activities.

  9. Documentation on system and products
  10. RSMCs operated by JMA provide up-to-date documentation on the technical characteristics of their operational system and on the products it delivers on JMA’s RSMC portal at http://www.jma.go.jp/jma/en/NMHS/JMA_RSMC.html

  11. Training
  12. RSMCs operated by JMA conduct training activities on the interpretation, performance characteristics, strengths and limitations of their products, based on the latest possible materials.

    Examples of trainings conducted by RSMCs operated by JMA include:

  13. Reporting on compliance
  14. RSMCs operated by JMA provide up-to-date information about the current implementation of their system on JMA’s RSMC portal at http://www.jma.go.jp/jma/en/NMHS/JMA_RSMC.html

  15. Graphical representation of observations, analyses and forecasts
  16. RSMCs operated by JMA that have a mandate of chart-based analysis maintain standardized weather forecasting process, including graphical representation of observations, analyses and forecasts.
