Advanced approaches in air quality forecasting combine historical data with data generated via on-ground sensors and satellite observations to provide insights, analysis, and forecasts from global to street-level air pollution. It also takes into consideration local factors like traffic, regional weather patterns, or emissions in the atmosphere.
Recently, drive-by air pollution sensing systems have emerged as a promising approach for air quality monitoring, utilizing sensors mounted on taxis, buses, trams, and other vehicles. [26] In particular, buses have garnered considerable attention as a mobile sensing platform due to their widespread availability and extensive geographical coverage.
Passive or "diffusive" air sampling depends on meteorological conditions such as wind to diffuse air pollutants to a sorbent medium. Passive samplers, such as diffusion tubes, have the advantage of typically being small, quiet, and easy to deploy, and they are particularly useful in air quality studies that determine key areas for future continuous monitoring.

The Air Quality Egg (AQE) is an Internet of Things platform and hobbyist device for crowdsourced citizen monitoring of airborne pollutants. The device won widespread recognition when it was named one of the best projects on Kickstarter in 2012, [ 1 ] and has been featured in a variety of media outlets. [ 2 ]
In other words, these expressions (AGL, AMSL, HAAT) indicate where the "zero level" or "reference altitude" is located. Absolute humidity – describes the water content of air and is expressed in either grams per cubic meter [2] or grams per kilogram. [3]
