Ongoing data collection from the MKE Fresh Air Collective sensor network, part of a harmonization database aggregating measurements from 10 unique US-based low-cost air quality sensor networks. The data is reformatted into a common format with embedded metadata and quality flags, curated by the LARC_CLOUD organization.
Use Cases
- Validate satellite-derived air pollutant concentrations using ground-based sensor measurements from the harmonized network.
- Assess data quality for specific pollutants using the embedded tier system and calibration-based quality flags.
- Analyze temporal trends in air quality by searching data based on date range and pollutant of interest.
- Compare sensor performance across different networks using the harmonized calibration criteria and metadata.
Strengths
- Data from 10 unique US-based sensor networks aggregated into a single framework
- Includes a tiered quality review system with data quality flags based on calibration efforts
Limitations
- Specific sample size, row count, and geographic coverage for the MKE Fresh Air network are unknown
- Data quality is variable and dependent on the calibration level of each contributing sensor network
