Size resolved denotes the capability of an instrument to measure aerosol properties in different size ranges. The size range of particles is typically given as a range of particle diameters in nm assuming spherical shape and must be provided in a comment attribute. Number concentration means the number of particles or other specified objects per unit volume. "Aerosol" means the suspended liquid or solid particles in air (except cloud droplets). "Dry aerosol" means aerosol without water.

"Number concentration" means the number of particles or other specified objects per unit volume. "Aerosol" means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself. Aerosol particles take up ambient water (a process known as hygroscopic growth) depending on the relative humidity and the composition of the particles. "Dry aerosol particles" means aerosol particles without any water uptake.
