Ballinderry River High-Frequency Water Quality Probe Data

A field probe records Dissolved Oxygen (% Saturation) and temperature (°C) in the Ballinderry River near Scotchtown Lane every 30 minutes. Data is collected by NIEA’s Freshwater Monitoring and Assessment team as part of a long-term project and is loaded onto the public platform approximately every 30 days. Measurements have an accuracy of +/- 5% for dissolved oxygen and +/- 0.1 degrees C for temperature.

Use Cases

• Modeling diurnal and seasonal water quality dynamics based on high-frequency temperature and dissolved oxygen readings.
• Assessing river health and potential hypoxic events based on dissolved oxygen saturation levels.
• Calibrating or validating hydrological models using long-term, high-frequency sensor data from a specific location.

Strengths

• High-frequency data collection with measurements recorded every 30 minutes.
• Sensor accuracy is specified as +/- 5% for dissolved oxygen and +/- 0.1 degrees C for temperature.
• Data is part of a long-term monitoring project, suggesting a continuous temporal record.

Limitations

• Data is described as non-validated and provisional, subject to revisions and sensor malfunction.
• Column-level documentation is absent; field semantics must be inferred after download.
• Geographic coverage is limited to a single probe location on the Ballinderry River.
