The air quality in Malaysia is reported as the API (Air Pollutant Index) or in Malay as IPU (Indeks Pencemaran Udara). Four of the index's pollutant components (i.e., carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide) are reported in ppmv but PM 2.5 particulate matter is reported in μg/m 3.
An air quality index (AQI) is an indicator developed by government agencies [1] to communicate to the public how polluted the air currently is or how polluted it is forecast to become.
Air pollution is the presence of substances in the atmosphere that are harmful to humans and other living beings, or cause damage to the environment. Air pollution can be chemical, physical or biological. [1]
The name of the airport was reported to be a suggestion from the people of Karo to the government and later granted by the Ministry of Transportation. [6] The name consists of two words: 'Kuala,' a Malay and Indonesian word for 'river mouth;' [7] and 'Namu' or 'Namo,' the Karonese for 'deep sea.' [8] Thus, 'Kualanamu' means 'meeting point.' [6] Kualanamu is one of the very few airports in the ...
An emission inventory (or emissions inventory [1]) is an accounting of the amount of pollutants discharged into the atmosphere.An emission inventory usually contains the total emissions for one or more specific greenhouse gases or air pollutants, originating from all source categories in a certain geographical area and within a specified time span, usually a specific year.
The ISA mathematical model divides the atmosphere into layers with an assumed linear distribution of absolute temperature T against geopotential altitude h. [2] The other two values (pressure P and density ρ) are computed by simultaneously solving the equations resulting from:

The density of air or atmospheric density, denoted ρ, [1] is the mass per unit volume of Earth's atmosphere.Air density, like air pressure, decreases with increasing altitude.
