In this study, we propose a simple method to derive vertically resolved aerosol particle number concentration ( N ) using combined polarimetric and lidar remote sensing observations. This relies on accurate polarimeter retrievals of the fine-mode column-averaged extinction cross section measurements coefficient such as those provided by multiwavelength high spectral resolution lidar. We compare...

The current regulated particle metric in vehicle emissions is the total mass, while during last decade interest in number size distribution has increased. Various international studies on epidemiology and toxicology have reported the adverse effect of the particle matter on public health. The UNECE group of experts on pollution and energy (GRPE) under particle measurement program (PMP) are u...
