Atmospheric Pollution

Strong winds dispersing pollution over a wider area

A strong temperature inversion layer trapping pollutants near ground level

Heavy rainfall washing pollutants out of the atmosphere

High atmospheric pressure systems causing rapid pollutant dilution

Industrial smog

Grey smog

Photochemical smog

Sulfurous smog

Low visibility

Contains a brownish color

Low levels of nitrogen oxides

Low levels of ground-level ozone

Rural farmlands

Dense forests

Urban areas

Coastal beaches

In the afternoon when sunlight intensity peaks

Early morning before sunrise

Late at night when traffic volume decreases

Immediately after sunset as temperatures cool down

The presence of greenspaces directly leads to massive foliage releases, adding additional quantities of pollutants and making situations worse.

The severity of local incidents is greatly influenced by the frequency with which these greenspaces are present, since they offer a surface and habitat for a variety of wildlife known to interfere with the smog formation process.

The presence of greenspaces inversely correlates to the potential severity of local incidents; they provide sinks and absorbents for some precursors, hence typically reducing the possibilities of occurrences.

There is no correlation between the presence of greenspaces and the severity of local incidents; it is purely dependent upon external climatic conditions.

It reduces the burning of coal by increasing prices for non-renewable energy sources city-wide.

It discourages driving during peak hours, leading to reduced emission of smog-forming pollutants from vehicles.

It promotes increased usage of electric heaters by raising electricity costs during off-peak hours only.

It encourages the development of more roads, spreading out traffic and decreasing overall vehicle density.

Greater heat causes greater wind dispersal of pollutant concentration

High temperatures naturally generate more VOCs from car exhaust

Increased speed and frequency chemical reactions between precursor pollutants

Warmer air holds more moisture leading to reduction in visibility

Driving gasoline-powered vehicles

Planting trees in urban settings

Constructing wind farms

Installing solar panels on rooftops

Building taller smokestacks to disperse industrial pollutants over a larger area.

Increasing green space in urban areas without addressing vehicular emissions.

Subsidizing the use of fertilizers that increase nitrogen runoff into local waterways.

Implementing stringent vehicle emissions standards to decrease nitrogen oxide output.
