Low-Cost Air Pollution Sensor Evaluation and Deployment Using Test Chambers and Mobile Platforms

Dear Colleagues,

Sensors are increasingly being used by consumers, community organizations, government agencies, and even academic research groups, to understand the status and composition of our atmosphere. As these sensors are roughly 1-2 orders of magnitude lower in cost compared to research/reference-grade monitors, they are often referred to as “low-cost sensors” (LCS). These devices require performance evaluations to properly interpret their output. Such evaluations are often conducted as ambient co-locations with reference monitors and the LCS, if deployed subsequently, are often used for stationary ambient measurement applications.

Performance evaluations of LCS in environmental chambers may be less common, but are still important to probe LCS behavior in extreme environmental conditions or pollutant concentrations that would not be achievable with ambient testing. In addition, using environmental chambers allows for the deliberate probing of LCS response to specific pollutant species or interferences. An even more nascent means of evaluating LCS performance is through the use of mobile platforms, which allows for characterization of LCS response to conditions of temperature, humidity, altitude, pollutant concentration, and turbulence that change more rapidly than in a stationary deployment scenario.

In this Special Issue, we invite works that contribute to the discussion of evaluating the performance of LCS in chambers and on mobile platforms, as well as the deployment of LCS following chamber testing or the use of LCS on mobile platforms for mobile monitoring. Examples of pertinent research include:

• Design and development of environmental chambers or mobile platforms for LCS evaluation;
• New LCS performance evaluation protocols using environmental chambers or mobile platforms;
• LCS performance evaluation results from environmental chambers or mobile platforms;
• Calibration of LCS using environmental chambers or mobile platforms, followed by validation and/or deployment of LCS in either stationary or mobile applications;
• Design and development of LCS specifically tailored for mobile deployment;
• Mobile monitoring using LCS;
• Novel methods using environmental chambers or mobile platforms to maintain or calibrate sensor networks;
• Novel data analysis or interpretation techniques for LCS measurements collected from mobile platforms.
