Members should use the monitoring information and reports provided by the WMO Lead Centre for aircraft and satellite data monitoring as an integrated component of the quality management operations of their AMDAR programme. Members should consider the development and implementation of additional monitoring procedures for AMDAR observational data, which might include: – Use of statistics and diagnostic results from their AMDAR quality control procedures (see 1.7.2.1 and Appendix A); – Use of the monitoring results of other WMO Member monitoring centres; – Use of AMDAR information available at the Global Data Centre for based Observations; – Intercomparison of AMDAR observations with NWP fields; – Intercomparison of AMDAR observations with other sources of upper-air observations, for example radiosonde data; – Monitoring diagnostics developed and based on other data analysis techniques such as: • Temporal consistency/gradient checks; • Spatial consistency/gradient checks; • Aircraft intercomparison; • Aircraft apparent velocity checks. Members should develop procedures for the analysis of available monitoring information and take prompt and appropriate corrective action (see 2.1.3.6) for systemic defects and issues identified that adversely affect the quality of AMDAR observations provided to WIS. Detailed guidance on quality monitoring and analysis of ABO data is provided in Appendix B. 2.1.3.4 Data management and reporting Members should develop policy and procedures for the management of their AMDAR observations in accordance with the provisions defined above and in sections 1.7, 1.8 and 1.9. 2.1.3.5 Metadata management and reporting Members that provide AMDAR observations to WIS must provide their AMDAR metadata in accordance with the provisions in the Manual on the WMO Integrated Global Observing System (WMO-No. 1160), 2.5 Observational metadata, 3.5 Observational metadata, and – – Appendix 2.4 The WIGOS metadata standard. – Members should manage and report their AMDAR metadata in accordance with the provisions and recommended practices referenced and provided in section 1.10 and Appendix D. 2.1.3.6 Systems operations and management An operational AMDAR system will have several important communications and components, which may include one or more of:
