Status report of IQWMA software GISC Beijing / CMA ET-WISC 2016 Integrated Quantitative WWW Monitoring Analysis

Background • In order to keep under review the efficient operation of the WWW, internationally co-ordinated monitoring on a non-realtime basis should be carried out periodically. - IWM 4 times a year (1 -15 Jan, Apr, Jul, Oct) - SMM - SAM • Integrated Weather Monitoring 4 times a year (1 -15 Jan, Apr, Jul, Oct) Special MTN Monitoring 1 times a year (1 -15 Jan) Special Antarctic Monitoring CMA has developed the integrated quantitative WWW monitoring analysis (IQWMA) software.

IQWMA workflow

Input to IQWMA software (1) Input reference data sets • Volume A | Volume C 1 | RBSN | RBCN | Routing Catalogues • Download from www. wmo. int/pages/prog/www/index_en. html

Input to IQWMA software (2) Input observational data • IWM(NMC/RTH/MTN) | SMM | SAM • Support individual or batch file(s) • Convert AGM to IWM

Output from IQWMA software (1) The analysis charts include: • Charts showing the percentage of reports received by the monitoring centres at each station in comparison with the reports expected from the RBSN/RBCN stations • Charts showing the reports not received by a WWW centre

Output from IQWMA software (2) The KML files can be opened with Google Earth • Maps showing the percentage of reports received by the monitoring centres at each station in comparison with the reports expected from the RBSN/RBCN stations • Maps showing the reports not received by a WWW centre

Integrated Weather Monitoring Analysis IWM Analysis The Integrated WWW Monitoring leads to the integration of the Annual Global Monitoring (AGM) and the Special MTN Monitoring (SMM) into one monitoring scheme. • The analysis of the monitoring reports will be done - by the Secretariat at the global level - by the RTHs at the regional level •

Special MTN Monitoring Analysis SMM Analysis • • One of the main features of the SMM is that the sets of messages provided by the various MTN monitoring centres are processed by a pre-analysis centre. The objective of the pre-analysis is to prepare files having a data-base structure and containing the information extracted from all the sets of messages. When a question is raised on specific bulletins, it is always possible to access the raw data and read the complete text of the bulletins as received by the monitoring centres.

Special Antarctic Monitoring Analysis SAM Analysis • The analysis of the SAM makes it possible to compare the availability of the reports received from ABSN/ABCN stations at collecting centre, at RTHs and at MTN centres.

OSCAR/Surface is different from Vol. A • “OSCAR/Surface will be launched on 2 May 2016, 2016 thereby replacing WMO No. 9, Volume A, Observing Stations and WMO Catalogue of Radiosondes. ” – http: //www. wmo. int/pages/prog/www/ois/Opera tional_Information/Newsletters/current_news_en. html – http: //www. wmo. int/pages/prog/www/wigos/do cuments/Vol. A-differences_v 2 -3. pdf

Vol. A field Difference in Comment OSCAR export file Region. Name almost the same English only Country. Area almost the same English only, sort order different. Textual changes possible Country. Code different ISO 3 instead of number code Station. Id WIGOS ID Built according to Attachment 2. 1 of the WIGOS Manual 1 approved by WMO 17 th Congress. Hp. Flag empty Hha. Flag empty Pressure. Def. Id Almost the same an entry for "mean sea level" was added SO-[1~8] empty Surface Obs at: 00/03/06/09/12/15/18/21 UA-[1~4] empty Upper Air Obs at: 00/06/12/18 Obs. Hs empty Obs. Rems empty (almost) “UA” if station makes Upper Air observations We have reported to WMO secretariat this problem. New additional source of observation time are necessary for IQWMA to run.
