Upper Bann River Water Quality Measurements at Portadown

High-frequency water quality data recorded every 30 minutes by a field probe deployed by the NIEA Freshwater Monitoring and Assessment team. The dataset contains measurements of Dissolved Oxygen (% Saturation) and temperature (°C) from the Upper Bann River, with data loaded onto a public platform approximately every 30 days. The probe uses an optical DO sensor with an accuracy of +/- 5% and a temperature sensor accurate to +/- 0.1°C.

Use Cases

• Modeling diurnal and seasonal dissolved oxygen cycles based on high-frequency, 30-minute interval data.
• Analyzing the relationship between water temperature and oxygen saturation in a freshwater river system.
• Monitoring for potential water quality events or sensor anomalies using provisional, real-time data streams.
• Establishing baseline water quality conditions for the Upper Bann River as part of a long-term monitoring project.

Strengths

• High temporal resolution with data recorded every 30 minutes.
• Sensor accuracy specifications are provided: dissolved oxygen +/- 5%, temperature +/- 0.1°C.
• Part of a long-term monitoring project, suggesting continuity of data collection.

Limitations

• Data is described as non-validated, provisional, and subject to revision.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
