Denver Air Quality Measurements from Low-Cost Sensor Network

Low-cost sensor data from the Love my Air Denver network provides ground-level air quality readings. This dataset is part of a harmonization framework integrating measurements from 10 unique US-based sensor networks, reformatted into a common structure with embedded metadata. Data collection is ongoing, managed by the LARC_CLOUD organization.

Use Cases

• Validate satellite-derived aerosol optical depth or NO2 column density using ground-level particulate matter and nitrogen dioxide sensor readings.
• Analyze temporal pollution trends by modeling time-series data for specific pollutants like ozone or carbon monoxide.
• Assess sensor network calibration quality by utilizing the embedded tier system and data quality flags for comparative analysis.
• Perform geospatial analysis of air pollution dispersion by mapping sensor locations and their corresponding pollutant concentration measurements.

Strengths

• Data from 10 unique US-based sensor networks harmonized into a single framework.
• Includes a tier system with data quality flags based on calibration efforts for user guidance.

Limitations

• Specific row count, column names, and temporal coverage for the Denver network are unknown.
• Relies on low-cost sensors which may have higher measurement uncertainty compared to reference-grade monitors.
