Probe Metrics

Northern Ireland's Ballinderry River is monitored by the NIEA Freshwater Monitoring and Assessment team using a field probe. The probe records Dissolved Oxygen (% saturation) and temperature (°C) every 30 minutes, with data loaded publicly approximately every 30 days. Data is provisional, non-validated, and collected as part of a long-term, high-frequency water quality monitoring project.

Use Cases

• Modeling diurnal and seasonal dissolved oxygen cycles based on high-frequency (30-minute) measurements.
• Analyzing temperature-dependent water quality dynamics in the Ballinderry River based on sensor data.
• Developing anomaly detection systems for sensor malfunction or environmental events based on provisional data streams.

Strengths

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

Limitations

• Data is explicitly flagged 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.
