"\"tendency_of_X\" means derivative of X with respect to time. \"Content\" indicates a quantity per unit area. \"Aerosol\" means the suspended liquid or solid particles in air (except cloud droplets). Aerosol takes up ambient water (a process known as hygroscopic growth) depending on the relative humidity and the composition of the aerosol. \"Dry aerosol\" means aerosol without water. \"Primary particulate organic matter \" means all organic matter emitted directly to the atmosphere as particles except black carbon. The sum of primary_particulate_organic_matter_dry_aerosol and secondary_particulate_organic_matter_dry_aerosol is particulate_organic_matter_dry_aerosol. \"Emission\" means emission from a primary source located anywhere within the atmosphere, including at the lower boundary (i.e. earth's surface). \"Emission\" is a process entirely distinct from \"re-emission\" which is used in some standard names."@en .
