ReCON Implementation of QARTOD How the QARTOD tests were programmed to provide quality assurance to the ReCON real-time data collection

The Realtime Coastal Observation Network (ReCON) collects data throughout the Great Lakes region from various in-situ sensors from the lake bottom to the surface and the immediate atmosphere and disseminates that information in real-time to data centers and stakeholders. The Integrated Ocean Observing System (IOOS), also under the National Oceanic and Atmospheric Administration (NOAA), has implemented a framework of quality control tests that assess the quality of data in real-time by automated processes. These tests are called the Quality Assurance / Quality Control of Real-Time Oceanographic Data or QARTOD. These tests have been used as a starting point for ReCON data quality assessment with some modifications as were deemed appropriate. This document details the ReCON implementation of the algorithms used by each test, the methodology in determining the appropriate parameter values for the tests, and some details of the operation of the software program developed.
