Abstract
The general concept of an open-path backscatter nephelometer, its design, principles of calibration and the operational use are discussed. The research-grade instrument, which operates at the wavelength 355 nm, will be co-located with a scanning-lidar at measurement sites near wildfires, and used for the lidar calibration. Such a near-end calibration has significant advantages compared with the conventional method of far-end calibration that assumes an aerosol-free atmosphere at some high altitude.
