The Optical Particle Counter (OPC) is an in situ optical instrument that measures aerosol particle size and concentration by detecting the intensity of scattered light. Most OPCs operate within the visible to near-infrared spectrum (500-1100 nm) and have a time resolution of 1 second. They are typically used to measure particles with diameters greater than 0.5 μm. OPCs can be deployed on both airborne and ground-based platforms.
