Reliable data from low cost ozone sensors in a ...

We demonstrate how a hierarchical network comprising a number of compliant reference stations and a much larger number of lowcost sensors can deliver reliable high temporalresolution ozone data at neighbourhood scales. The larger than expected spatial and temporal variation of ozone in a heavilytrafficked urban environment is thereby demonstrated. The framework, demonstrated originally for ...

Distributed MultiScale Calibration of LowCost Ozone ...

New advances in sensor technologies and communications in wireless sensor networks have favored the introduction of lowcost sensors for monitoring air quality applications. In this article, we present the results of the European project H2020 CAPTOR, where three testbeds with sensors were deployed to capture tropospheric ozone concentrations. One of the biggest challenges was the calibration ...
