Nitrogen Oxides Hourly Air Quality Measurements for Lower Austria

Hourly mean values of nitrogen oxides (NOx) are provided by the Lower Austrian Air Quality Monitoring Network. The data is updated every hour and contains one-hour mean values in µg/m³ for the current day. The dataset is published by Cooperation OGD Österreich and Wikimedia Österreich under a CC-BY-4.0 license.

Use Cases

• Modeling short-term air pollution exposure based on hourly NOx concentrations
• Analyzing diurnal patterns of nitrogen oxides based on hourly mean values
• Validating regional air quality models with current-day monitoring data
• Assessing compliance with air quality standards using hourly pollutant levels

Strengths

• Data is updated every hour, providing near real-time information
• Measurements are provided in a standardized unit (µg/m³) as one-hour mean values

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data coverage is limited to the current day, with no historical archive provided in the daily file
