Lecture (1): The Atmosphere and Its Composition

• The atmosphere is a layer of gases surrounding Earth, primarily oxygen and nitrogen, which protects and supports life.
• Functions: Protection (shielding from harmful solar radiation), Regulation (maintaining Earth's temperature), and Support (providing air and water cycles).
• The structure of the atmosphere is discussed, including characteristics of different layers.

Atmosphere Composition

• Introduction to atmospheric structure
• Gaseous composition of the atmosphere.
• Gases, droplets, and particles surrounding Earth's surface

Relevant Terms

• Atmosphere: Gases, droplets, and particles surrounding Earth's surface.

• Weather: Atmospheric conditions at a specific time and place. -Temperature, humidity, precipitation, wind, visibility

• Climate: Long-term weather patterns and averages over time

• Climatology: scientific study of climate

• Homosphere: The lowest 80 km of the atmosphere. Relative abundance of permanent gases is constant.

• Heterosphere: Higher atmosphere. Gases not well mixed; stratified by weight. Lighter-weighing gases are found here.

Composition of the atmosphere:

• Permanent gases:

  • Nitrogen (N₂): 78.08% (by volume)
  • Oxygen (O₂): 20.95% (by volume)
  • Argon (Ar): 0.93% (by volume)

• Variable gases:

  • Water Vapor (H₂O)
  • Carbon Dioxide (CO₂)
  • Ozone (O₃)

• Aerosols: Small solid particles or liquid droplets in the air, formed by natural and anthropogenic processes

  • Dust, smoke, volcanic ash

• Composition of Atmosphere Near Earth's surface

• Table 3.2 (page 44)

Vertical Structure of the Atmosphere

• The atmosphere consists of several distinct layers with unique characteristics
  • Troposphere
  • Stratosphere
  • Mesosphere
  • Thermosphere
  • Exosphere

Atmosphere Pressure

• Atmospheric pressure is the weight of air above a given point. It decreases with altitude.

• Ozone layer: A crucial part of the stratosphere, found approximately 10 to 30 kilometers above the Earth's surface. Ozone (O3) molecules absorb and scatter ultraviolet solar radiation.

Importance of the Ozone Layer

• UV radiation protection
  • Absorbs most of the Sun's harmful UV radiation
  • Protects humans, animals, and plants from the damaging effects of UV radiation
• Environmental balance
  • Maintains the balance of ecosystems
  • Protects biodiversity

Ozone Depletion and Causes

• Chlorofluorocarbons (CFCs): Man-made chemicals once used in refrigerants, air conditioning, and aerosols
• Halons: used in fire extinguishers
• Other chemicals: Impact ozone depletion

Other Atmospheric Layers

• Troposphere: Extends up to 8-15 km, contains most atmospheric mass, weather phenomena, and clouds. Temperature decreases with altitude.

• Stratosphere: Extends up to about 50 km, contains the ozone layer, which absorbs UV radiation, Temperature increases with altitude.

• Mesosphere: Extends up to about 85 km, the coldest layer of the atmosphere, meteors burn up here. Temperature decreases with altitude.

• Thermosphere: Extends up to about 600 km, temperature increases significantly with altitude, contains the ionosphere reflecting radio waves.

• Exosphere: Extends up to about 10,000 km, outermost layer, atmospheric particles sparse

• Summary: Divisions of the atmosphere by temperature characteristics.
