Low-Cost PM Sensor Calibration Data Against Reference-Grade Fidas 200S

Florentin M. J. Bulot and colleagues from the University of Southampton provide sensor data used for analyzing and calibrating low-cost particulate matter sensors against a reference-grade instrument. The dataset includes median mass and particle number concentrations for PM1, PM2.5, PM4, and PM10 from sensors like the SPS30 and PMS5003, alongside data from a Fidas 200S reference monitor. Data collection likely occurred between July 2020 and July 2021, as indicated by a primary filename.

Use Cases

• Calibrating low-cost PM sensor readings based on median_PM25 and median_PM10 columns against reference-grade Fidas 200S data.
• Analyzing particle size distribution patterns based on particle number concentration columns like median_n05 and median_gr03um.
• Comparing performance of different sensor models (e.g., SPS30 vs. PMS5003) based on their respective mass and number concentration outputs.
• Developing correction algorithms for low-cost sensors using the provided cf1 calibration data columns (e.g., median_pm25_cf1).

Strengths

• Data is directly linked to a peer-reviewed pre-print paper, providing methodological context.
• Includes measurements from both low-cost sensors and a reference-grade Fidas 200S instrument, enabling performance comparison.
• Covers multiple particulate matter metrics, including mass concentrations for PM1, PM2.5, PM4, PM10 and particle number concentrations across several size bins.

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation beyond header names is absent; detailed field semantics must be inferred from the associated paper.
• The geographic coverage of the monitoring sites is not specified in the provided metadata.
