2 Factors of air temperature

latitude, elevation

Maritime

Coastal areas summer and winter temperatures not as different (Maritime or Continental)

Continental

Middle of continents hottest in summer and coldest in winter (Maritime or Continental)

Windward

ocean moderate temperature – warmer winter and cooler summer (windward or leeward)

Leeward

continent bring more extreme temperatures –colder winter and hotter summer (windward or leeward)

Solid Particles (soot & dust)

bad for lungs

Sulfur Oxides (SOx)and Nitrogen Oxides (NOx)

Acid Rain which harms/kills plants & aquatic wildlife; irritates lungs

Heavy Metals – Mercury (Hg), Lead (Pb) & others

toxins to humans & other animals/plants

Carbon Dioxide (CO2) and Methane (CH4)

Increased greenhouse effect, Global Warming/Climate Change

Ground Level Ozone (O3)

irritates respiratory system

Chlorofluorocarbons (CFCs such as CFCl3)

destroy ozone layer (good news - banned by global treaty in 1990’s)

Soot and Dust Source

forest fires, burning coal & burning diesel fuel, farming, wood stoves (Source)

SOx and NOx Source

Burning coal, diesel, gasoline (Source)

CO2 Source

Burning fossil fuels, deforestation, making cement (Source)

CH4 (methane) Source

natural gas drilling/pipelines, agriculture, landfills (Source)

Ozone layer Source

burning gasoline, diesel (Source)

CFC’s Source

refrigerants in air conditioners, refrig/freezers (Source)

Heavy Metals Source

Burning Coal, Hg, Pb & others various industries (Source)
