Study Notes
Air Quality Monitoring
- Air quality monitoring network in India includes both online and manual monitoring.
- Air quality monitoring is crucial in places of high natural environmental value to preserve natural ecosystems.
Air Pollution Indices
- Eclipsing occurs when pollution is underestimated in the context of air pollution indices.
- This means that the actual pollution levels are higher than reported.
Air Quality Models
- Non-reactive models deal with pollutants like PM, SO2, and CO.
- These models do not account for chemical reactions between pollutants.
Screening Models
- Screening models are characterized by simple estimations with worst-case meteorological conditions.
- They are used to quickly assess the impact of air pollution on a given area.
Atmospheric Stability and Plumes
- There is a critical relationship between atmospheric stability and pollutant concentrations in relation to plumes.
- The vertical motion of air parcels affects the dispersion of pollutants.
Plume Types
- Under the neutral lapse rate, when wind speed is greater than 32 km per hour, the Coning plume type exists.
- This type of plume is characterized by a specific shape and behavior.
Dispersion of Air Pollutants
- The exit velocity of a plume influences the dispersion of air pollutants.
- Turbulence, consisting of irregular swirls of motion of wind called eddies, also affects dispersion.
- The mixing height determines the volume of atmosphere available for dispersion, which affects the spread of pollutants.
