Record Label : mass_fraction_of_ammonium_dry_aerosol_particles_in_air
Record Title : Mass Fraction of Ammonium Dry Aerosol Particles in Air
CF Standard Name : mass_fraction_of_ammonium_dry_aerosol_particles_in_air
Record Description : Mass fraction is used in the construction mass_fraction_of_X_in_Y, where X is a material constituent of Y. It means the ratio of the mass of X to the mass of Y (including X). "Mass_fraction_of_ammonium" means that the mass is expressed as mass of NH4. "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.
