Cross-calibrating low-cost PM2.5 sensors

Can colocated low-cost sensors reproduce a reference monitor’s hourly readings?

ReplicationReplication or benchmark. A fixed evaluator decides the outcome.

Success means

Freeze calibration and subsequent blind periods; achieve mean absolute error at most 5 µg/m³ on the blind period and report humidity-dependent bias and missing hours.
