TS 16. Fundamentals of Low-Cost Aerosol Sensors

Presented by:  John Volckens

Location: La Cienega

Abstract: The recent proliferation of low-cost (optically based) aerosol sensors has enabled a wave of new scientific research, along with reams of data. This tutorial will cover the principles of sensor operation, their strengths and limitations, and the challenges/opportunities when working with data they produce. Topics covered will include the fundamental physics of light scattering, sensor teardowns and physical-optical modeling, sensor use (and misuse), data handling, and various calibration schemes.
