Quebec Nomadic Air Pollutant Concentration Measurements

A nomadic air quality monitoring station in Quebec measures concentrations of ozone (O3), fine particles (PM2.5), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOx), elemental carbon (CE), and ultrafine particles (PUF). The station relocates after each 12- to 24-month measurement campaign to deepen knowledge of ambient air quality.

Use Cases

• Analyze trends in ozone (O3) and fine particle (PM2.5) concentrations across different station locations over time.
• Model correlations between nitrogen oxides (NOx) and carbon monoxide (CO) levels from continuous measurements.
• Assess spatial variability of sulfur dioxide (SO2) and elemental carbon (CE) through the station's relocation.
• Study the relationship between ultrafine particles (PUF) and spot-measured breathable particles (PM10).

Strengths

• Measures 7 key pollutants continuously, including ozone (O3), PM2.5, and nitrogen oxides (NOx).
• Station relocates after 12- to 24-month campaigns, providing data from multiple geographic contexts.
• Includes spot measurements for breathable particles (PM10) and total suspended particles (PST) with metal analysis.

Limitations

• Row count, column count, and sample data are unavailable, hindering assessment of dataset scale and structure.
• Data is from a single nomadic station, limiting spatial coverage compared to a fixed network.
• The description is an automated translation, which may introduce inaccuracies in metadata.
