Air Quality Along Roads 2009: Dutch Monitoring for NO2 and PM10

The National Air Quality Cooperation Programme (NSL) contains measures to ensure compliance with European limit values throughout the Netherlands. Monitoring began in 2010 using a Monitoring Tool to track air quality development and the implementation of measures. The limit value for nitrogen dioxide (NO2) is 40 µg/m³, and for particulate matter (PM10) it is 40 µg/m³ yearly average and a daily average of 50 µg/m³.

Use Cases

• Assessing compliance with the 40 µg/m³ NO2 limit value based on monitoring data.
• Tracking progress toward the 2011 PM10 limit value based on yearly and daily averages.
• Evaluating the impact of spatial developments on air quality based on NSL calculations.
• Modeling roadside air pollution concentrations based on monitoring tool outputs.

Strengths

• Data is tied to a formal national program (NSL) with defined legal limit values.
• Description specifies precise numerical targets for NO2 (40 µg/m³) and PM10 (40 µg/m³ yearly, 50 µg/m³ daily).
• Data is provided in multiple machine-readable formats including JSON and WFS.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
