Upper Bann River Water Quality: Dissolved Oxygen and Temperature at Portadown

Probes is a high-frequency water quality monitoring dataset from the Northern Ireland Environment Agency's Freshwater Monitoring and Assessment team. It records Dissolved Oxygen (% saturation) and temperature (°C) in the Upper Bann River at Portadown every 30 minutes. Data is loaded onto the public platform approximately every 30 days and is provided as provisional, non-validated information.

Use Cases

• Modeling diurnal and seasonal dissolved oxygen cycles based on high-frequency 30-minute measurements.
• Analyzing temperature fluctuations and their potential impact on river ecology based on sensor data with +/- 0.1°C accuracy.
• Developing anomaly detection systems for sensor malfunction or environmental events based on provisional, real-time data streams.
• Correlating water quality parameters with other environmental datasets for the Upper Bann River catchment area.

Strengths

• High-frequency temporal resolution with measurements recorded every 30 minutes.
• Sensor accuracy is specified: dissolved oxygen +/- 5% saturation, temperature +/- 0.1°C.
• Data collection is part of a long-term monitoring project, suggesting a continuous time-series.

Limitations

• Data is explicitly flagged as non-validated and provisional, subject to revision.
• Column-level documentation is absent; field semantics must be inferred after download.
• Geographic coverage is limited to a single probe location on the Upper Bann River at Portadown.
