Preferred term

mass_concentration_of_nitric_acid_trihydrate_ambient_aerosol_in_air  

Definition

  • Mass concentration means mass per unit volume and is used in the construction mass_concentration_of_X_in_Y, where X is a material constituent of Y. A chemical species denoted by X may be described by a single term such as 'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. "Aerosol" means the suspended liquid or solid particles in air (except cloud droplets). "Ambient aerosol" is aerosol that has taken up ambient water through hygroscopic growth. The extent of hygroscopic growth depends on the relative humidity and the composition of the aerosol. The chemical formula for nitric acid is HNO3. Nitric acid trihydrate, sometimes referred to as NAT, is a stable crystalline substance consisting of three molecules of water to one molecule of nitric acid.
