It is measured by the pollution index
measured as humidity in the air with a hygrometer.
Air temperature can be measured beyond the troposphere.
The highest temperature recorded in the UK in 2005 was 36.5°C (97.7°F) and it was measured in Wisley, Surrey.

PPM by volume is typically measured using a gas concentration analyzer or gas detector. The device measures the volume of a particular gas in a given volume of air and expresses it in parts per million (PPM). This measurement is commonly used in environmental monitoring, industrial hygiene, and indoor air quality assessments.
Particulate matter and ozone.
Lead is not a major air pollutant measured by the air quality index. The major air pollutants measured are sulfur dioxide, carbon monoxide, and particle pollution (PM2.5 and PM10). Lead is a toxic metal that can be harmful when ingested or inhaled but is not typically included in standard air quality monitoring.
In the UK, air pollution contributes to around 5% of all deaths annually. Pollutants such as nitrogen dioxide and particulate matter from vehicles and industry are major contributors to poor air quality in urban areas. Efforts to reduce emissions and improve air quality are ongoing.
A measured increase in air temperature just above the ground is known as a temperature inversion. This phenomenon occurs when warm air moves over cold air near the surface, trapping pollutants and leading to poor air quality.

The quality of leather is measured by the air-tightness, absorbancy to the dye, and flexibility. London Fog produces fantastic leather jackets from high quality leather.
