A forecast of air quality conditions valid during a period. Air quality index is a number used to report the quality of the air on any given day. A concentration value is associated with a chemical entity. The concentration of a chemical compound. A chemical entity is a physical entity of interest in chemistry including molecular entities, parts thereof, and chemical substances. A simulation or measurement of a chemical specie has a concentration value. A simulation has a forecast instance. A purely intentional entity that simulates an entity and its properties. A simulation or measurement is located in an administrative municipality. A simulation or measurement has an atmospheric pressure value. A physical quality that inheres in a bearer by virtue of the bearer's amount of force per unit area it exerts. A simulation or measurement has an temperature value. Measured temperature. A simulation or measurement has an associated timestamp in currentmillis. A simulation or measurement value has a unit in the SI. A simulation or a measurement of a physical or chemical parameter has a numeric value. A value is result of a simulation. An azane that consists of a single nitrogen atom covelently bonded to three hydrogen atoms. A molecular entity that contains no carbon. A one-carbon compound in which the carbon is attached by single bonds to four hydrogen atoms. It is a colourless, odourless, non-toxic but flammable gas (b.p. −161°C). A one-carbon compound in which the carbon is joined only to a single oxygen. It is a colourless, odourless, tasteless, toxic gas. Any molecule that consists of at least one carbon atom as part of the electrically neutral entity. A sulphur oxide composed by one sulphur atom and one oxygen atom. Any constitutionally or isotopically distinct atom, molecule, ion, ion pair, radical, radical ion, complex, conformer etc., identifiable as a separately distinguishable entity. An elemental molecule with formula O3. An explosive, pale blue gas (b.p. −112°C) that has a characteristic, pungent odour, it is continuously produced in the upper atmosphere by the action of solar ultraviolet radiation on atmospheric oxygen. It is an antimicrobial agent used in the production of bottled water, as well as in the treatment of meat, poultry and other foodstuffs. A molecular entity all atoms of which have the same atomic number. A nitrogen oxide composed by one nitrogen atom and two oxygen atom. A nitrogen oxide composed by one nitrogen atom and one oxygen atom. A nanosized spherical or capsule-shaped structure. The date and time of this observation represented by an ISO8601 interval.
