The growing use of sensors in fresh waters for water quality measurements generates an increasingly large amount data that requires assurance (QA)/quality control (QC) before the results can be exploited. Such a process is often resource-intensive and may not consistent across users sensors. SentemQC (QA-QC high temporal resolution sensor data) cost-efficient, open-source Python approach developed to ensure by performing QA QC on volumes high-frequency (HF) data. method computationally efficient features six-step user-friendly setup anomaly detection. marks anomalies using five moving windows. These windows connect each point neighboring points, including those further away window. As result, mark only individual outliers but also clusters anomalies. Our analysis shows robust detecting HF from multiple measuring nitrate, turbidity, oxygen, pH. were installed three different freshwater ecosystems (two streams one lake) experimental lake mesocosms.
