Air pollution measurement is the process of collecting and measuring the components of air pollution, notably gases and particulates. The earliest devices used to measure pollution include rain gauges (in studies of acid rain ), Ringelmann charts for measuring smoke , and simple soot and dust collectors known as deposit gauges .

Since the upper layers are colder, the amount emitted would be lower, leading to warming of Earth until the reduction in emission is compensated by the rise in temperature. [1] Furthermore, such warming may cause a feedback mechanism due to other changes in Earth's albedo, e.g. due to ice melting.
This has led to increases in mean global temperature, or global warming. The likely range of human-induced surface-level air warming by 2010–2019 compared to levels in 1850–1900 is 0.8 °C to 1.3 °C, with a best estimate of 1.07 °C. This is close to the observed overall warming during that time of 0.9 °C to 1.2 °C.
[5] [6] As a result, global warming of about 1.2 °C (2.2 °F) has occurred since the Industrial Revolution, [7] with the global average surface temperature increasing at a rate of 0.18 °C (0.32 °F) per decade since 1981. [8] All objects with a temperature above absolute zero emit thermal radiation.
There are five types of air pollution dispersion models, as well as some hybrids of the five types: [1] Box model – The box model is the simplest of the model types. [2] It assumes the airshed (i.e., a given volume of atmospheric air in a geographical region) is in the shape of a box.
Global warming occurs when earth receives more energy than it gives back to space, and global cooling takes place when the outgoing energy is greater. [3] Multiple types of measurements and observations show a warming imbalance since at least year 1970. [4] [5] The rate of heating from this human-caused event is without precedent.
[266] [267] Climate change mitigation is interconnected with various health co-benefits, such as those from reduced air pollution. [267] Air pollution generated by fossil fuel combustion is both a major driver of global warming and the cause of a large number of annual deaths. Some estimates are as high as 8.7 million excess deaths during 2018.
