The U.S. Integrated Ocean Observing System® (IOOS®) has a vested interest in collecting high quality data for the 34 core variables (https://ioos.noaa.gov/about/ioos-by-the-numbers) measured on a national scale. In response to this interest, U.S. IOOS continues to establish written, authoritative procedures for the quality control (QC) of real-time data through the Quality Assurance/Quality Control of Real-Time Oceanographic Data (QARTOD) program, addressing each variable as funding permits (UNESCO 1993). This manual update on the real-time QC of high frequency (HF) radar surface currents represents the ninth core variable to be addressed. Other QARTOD guidance documents that have been published by the U.S. IOOS project to date are listed below and are also available at https://ioos.noaa.gov/project/qartod/ - manuals.

Bushnell, Mark
The U.S. Integrated Ocean Observing System (IOOS) Quality Assurance/Quality Control (QA/QC) of Real-Time Oceanographic Data (QARTOD) Project Plan was established in early 2012 and has now reached its ten-year anniversary. This report marks that ten-year point by documenting QARTOD history and successes, and then outlining opportunities for future accomplishments.
The first QARTOD project plan provided guidance for how the QARTOD process would work. A subsequent update created the existing manual format, adopted a flagging standard for QARTOD manuals, and documented efforts to implement QC tests.
This third iteration of the project plan is different from the other plans/updates in that it shifts the focus from an IOOS-led effort to a community-driven development of QARTOD manuals. This update is designed to help communities whose variables of interest (any variable relevant to IOOS but particularly biogeochemical variables) are not yet ready for a traditional QARTOD QC manual but are likely to benefit from the development of a QA/QC standardized process in the near future. This update helps provide a framework for those communities moving forward.
2022-01-01T00:00:00ZManual for Real-Time Quality Control of Water Level Data: A Guide to Quality Control and Quality Assurance for Water Level Observations. Version 2.1https://repository.oceanbestpractices.org/handle/11329/15472023-06-14T18:54:31Z2021-01-01T00:00:00ZManual for Real-Time Quality Control of Water Level Data: A Guide to Quality Control and Quality Assurance for Water Level Observations. Version 2.1
The purpose of this manual is to provide guidance to the U.S. IOOS and the WL community at large for the real-time QC of WL measurements using an agreed-upon, documented, and implemented standard process. This manual is also a deliverable to the U.S. IOOS Regional Associations and the ocean observing community and represents a contribution to a collection of core variable QC documents.
WL observations covered by these test procedures are collected in oceans and lakes in real time or near-real time. These tests are based on guidance from QARTOD workshops (QARTOD 2003-2009) and draw from existing expertise in programs such as the National Oceanic and Atmospheric Administration National Ocean Service (NOAA/NOS) National Water Level Observation Network (NWLON) (Nault 2004), the University of Hawaii Sea Level Center, and the Global Sea Level Observing System (GLOSS). The Global Climate Observing System recognizes GLOSS as one of the international operational activities that provides essential sea level climate data. The GLOSS Global Core Network is comprised of 290 globally distributed sea level stations (23 in the U.S.) (GLOSS 2012).
This manual differs from existing QC procedures for WL in that its focus is on real-time data. It presents a series of eleven tests that operators can incorporate into practices and procedures for QC of WL measurements. These tests apply only to the in-situ, real-time measurement of WL as observed by sensors deployed on fixed platforms and not to remotely sensed WL measurements (e.g., satellite observations).

The United States Integrated Ocean Observing System® (U.S. IOOS®) Quality Assurance / Quality Control of Real-Time Oceanographic Data (QARTOD) Project marshaled hundreds of volunteer subject-matter experts to identify tests to evaluate real-time data quality by variable and instrument type. These quality control steps, outlined in QARTOD manuals, are crucial for documenting the reliability of the collected real-time environmental data. QARTOD, which began as an ad hoc effort in 2003, has published thirteen quality control manuals. Specific aspirations for future QARTOD efforts include revising existing manuals, identifying new manuals for development based on the QARTOD community development process, and promoting the documented quality control procedures within the IOOS and broader ocean observing system communities.
QARTOD manuals characterize the quality control processes as required, strongly recommended, or suggested for each sensor type. QARTOD manuals can be developed only when, 1) interoperable data streams are employed, 2) data are disseminated and used in real-time, and 3) there is sufficient community expertise and interest. An initial review of U.S. IOOS core variables and Global Ocean Observing System Essential Ocean Variables (considering these three requirements) reveals no remaining variables with an immediate need for manual development. As technologies advance, the observational maturity increases for these variables, as will the need for a QARTOD manual.
QARTOD QC tests are now being implemented by operators at ocean observing systems around the world. Technological progress (e.g., autonomous vehicles) suggests a high potential for expanding the real-time quality control measures integrated within field instrumentation. Most required QARTOD tests can be embedded and implemented within the field-deployed equipment, and QARTOD-ready devices likely will be available soon. As the Internet of Things grows to include oceanographic hardware (Xu et al. 2019), such embedded QC processes will become important.

Most operators provide real-time data on a provisional basis, alerting users that post-processing is required to validate their data. However, even these provisional data should be quality controlled. Data released in real time should be subjected to automated QC processes, which: 1) provide a quality-control indicator, 2) alert the operator when questionable or interesting data are presented, and 3) prevent the dissemination of unreliable data.
These practices for sensor QC of phytoplankton data were developed by operators with experience using a variety of sensors and detection technologies.
