New Manual Released:

As part of the U.S. IOOS Data Management and Communication (DMAC) core services, the U.S. IOOS Program Office has issued the Manual for Real-Time Quality Control of pH Data Observations. This manual is a living document that reflects the state-of-the-art QC testing procedures for real-time pH Data observations. It is written for the experienced operator but also provides examples for those who are just entering the field.

Real-time Quality Control Manuals

These manuals are living documents that reflect the state-of-the-art QC testing procedures for real-time in-situ current observations.

Key Objectives

The key objective of QARTOD is to sustain a process for establishing QA/QC procedures that will:

  • Establish authoritative QA/QC procedures for the U.S. IOOS core variables, as necessary, including detailed information about the sensors and procedures used to measure the variables.
  • Produce written manuals for these QA/QC procedures
  • From the list of individual QA/QC procedures and guidelines developed, define a baseline set of QA/QC procedures that can be used for certification of RCOOS data providers
  • Facilitate QA/QC integration with Global Ocean Observing System (GOOS) and other international ocean observation efforts
  • Engage the Federal Agencies and IOOS Regions that are part of, or contribute to, US IOOS who will use the established QA/QC procedure
  • Work efficiently, without duplication of effort, to facilitate the implementation of common QA/QC procedures amongst US IOOS Partners.

Project Plan

QARTOD is a continuing multi-agency effort that started in 2003.

QARTOD Meetings - Access agendas, reports, presentations and more from the QARTOD Meetings.

Project Documentation
The Project Plan describes how the project works, deliverables, the roles and the responsibilities of the participants, the structure of the QARTOD, and information about the key supporting organizations/roles.
