Municipal Air Quality Health Index Hourly Percentages

Government of Alberta data lists the percentage of hours each year at specific air quality levels by municipality. The Air Quality Health Index is calculated from ground-level ozone, particulate matter, and nitrogen dioxide. Risks are categorized as High Quality (1-3), Moderate Quality (4-6), Low Quality (7 -9), and Very Low Quality (10+).

Use Cases

• Analyze trends in the percentage of hours at Low or Very Low Quality levels across municipalities over time.
• Model correlations between air quality risk categories (1-3, 4-6, 7-9, 10+) and seasonal or industrial factors.
• Compare municipal performance by calculating annual distributions of hours across the four defined air quality levels.

Strengths

• Data is provided by the Government of Alberta, an authoritative public source.
• Index is based on a defined combination of common pollutants: ozone, PM2.5/PM10, and nitrogen dioxide.
• Risk levels are clearly categorized into four distinct bands from High to Very Low Quality.

Limitations

• The dataset's temporal coverage, row count, and specific column structure are unknown.
• Data granularity is limited to annual percentages of hours, not raw hourly measurements or pollutant concentrations.
