"2017-07-24 14:37:00.0" . . "\"tendency_of_X\" means derivative of X with respect to time. \"Content\" indicates a quantity per unit area. The \"atmosphere content\" of a quantity refers to the vertical integral from the surface to the top of the atmosphere. For the content between specified levels in the atmosphere, standard names including \"content_of_atmosphere_layer\" are used. The mass is the total mass of the particles. The specification of a physical process by the phrase \"due_to_\" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. \"Emission\" means emission from a primary source located anywhere within the atmosphere, including at the lower boundary (i.e. the surface of the earth). \"Emission\" is a process entirely distinct from \"re-emission\" which is used in some standard names. \"Aerosol\" means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself. Aerosol takes up ambient water (a process known as hygroscopic growth) depending on the relative humidity and the composition of the aerosol. \"Dry aerosol particles\" means aerosol particles without any water uptake. The mass is the total mass of the particles. The \"residential and commercial combustion\" sector comprises fuel combustion activities related to the commercial/institutional sector, the residential sector and the agriculture/forestry/fishing sector. It may also include any not-classified or \"other\" combustion, which is commonly included in the inventory data. \"Residential and commercial combustion\" is the term used in standard names to describe a collection of emission sources. A variable which has this value for the standard_name attribute should be accompanied by a comment attribute which lists the source categories and provides a reference to the categorization scheme, for example, \"IPCC (Intergovernmental Panel on Climate Change) source categories 1A4a, 1A4b and 1A4c as defined in the 2006 IPCC guidelines for national greenhouse gas inventories\". Chemically, \"elemental carbon\" is the carbonaceous fraction of particulate matter that is thermally stable in an inert atmosphere to high temperatures near 4000K and can only be gasified by oxidation starting at temperatures above 340 C. It is assumed to be inert and non-volatile under atmospheric conditions and insoluble in any solvent (Ogren and Charlson, 1983)."@en . "accepted"@en . "SDN:P07::KE3VGDT1" . "3" .
