  1. National Monitoring Network ReportMethods and Data Comparability Chapter 5 Outline National Monitoring Council Meeting April 12-14, 2005

  2. Chapter 5 Outline • 5.1 Background – Statement of Problem fromMethods and Data Perspective • Lack of comparability and why • Causes for data gaps • Need for methods and data comparability and how that leads to information sharing • Data Quality and Measurement Quality Objectives and defining data quality • Tradeoffs – increasing specificity of monitoring effort can limit wide usage and how to overcome

  3. Chapter 5 Outline • 5.2 Sharing Data Across Boundaries • Transparency in data systems and data system architecture • Data system boundaries -- Internet & interoperability issues, data storage • Data security issues • Functionality • Data transport • Examples of data shared across state boundaries, e.g., Pacific Northwest Data Exchange

  4. Chapter 5 Outline • 5.3 Need for Meta Data and Data Sharing Mechanisms • Laboratory and field method characterization • Water Quality Data Elements • Fields necessary for generating comparable metadata • NEMI • How NEMI can be used to select methods with appropriate QA/QC and other elements that lead to comparability • Developing expert system – ensure that metadata related to each element of Monitoring Framework is compatible with methods selected for sampling & analysis, QA/QC, data base fields, and other monitoring goals (DQOs, MQOs) • Minimum metadata requirements

  5. Chapter 5 Outline • 5.3 (continued) • Minimum data formatting requirements • Data and metadata web accessibility • Development and maintenance of metadata • Adaptability of metadata • Subsetting data • Aggregating data • Products and merging data • Tracking metadata maintenance • Data quality metadata • Complete metadata • Archive of metadata

  6. Chapter 5 Outline • 5.4 Need for Use of New and Innovative Technologies • New technologies in assuring comparability • Network focus on technology advancements to improve the the quality and affordability of water monitoring • Impact of technologies developed related to water security

  7. Chapter 5 Outline • 5.5 Case Study Examination • DQOs and MQOs Established? • Field and Sampling Protocols and Procedures Used • Available Data and Metadata • Comparability of Existing Information Using Tools Outlined Previously

  8. Chapter 5 Outline • 5.6 Competition for Resources • Refer back to many other reasons for monitoring not specifically addressed in report • Recapitulate various solutions/recommendations Should 5.5 be in this Chapter?

  9. Technical Appendices • WQDE Guide • Value of Comparability Fact Sheet • NEMI Fact Sheet and NEMI-CBR Poster info • NOAA Products – IOOS Management and communications • Value of Laboratory Accreditation Fact Sheet and Federal Laboratory Accreditation Paper • PBS Report • Paper discussing DQOs and MQOs in nitrate measurement • Part of IMPACT paper? Could be used more broadly in report • Other?
