How Many PM2.5 Sensors are Needed to Estimate Daily and Annual Deployed-Network Mean Concentrations in City-Scale Sensor Networks?

Low-cost PM2.5 sensors make it possible to deploy dense networks, but the density required depends on the monitoring objective and local variability. We examined how well smaller subnetworks reproduce deployed-network daily and annual or study-period mean concentrations using data from Dhaka, Bangladesh (N = 35; annu...
