Ecosystem Services of the Atmosphere“Ecosystem Services are the benefits people get from the
ecosystem” (greenfacts.org)
- How do we benefit from the atmosphere?
- How does the atmosphere make life possible on Earth?
A. Ozone layer
B. Greenhouse gases
C. Weather and Climate
D. Solar Energy and TemperatureRegulation
E. Protection from Meteors

Ozone Layer Stratosphere, 20-30 km from Earth’s surface O+O2 = O3
Protection from UV radiation UV causes:
- cataracts, immune system suppression, genetic damage, skin cancer
Environmental Concern: depleting ozone layer> Action Taken: CFC (chlorofluorocarbons) prohibition

Greenhouse Gases Water vapor, carbon dioxide, nitrous oxide, methane Absorbs heat from sun and re-radiate back to Earth’s surface
(papers.ssrn.com)
> without them surface temperature is about -18 degrees Celcius (0 degrees Fahrenheit) (ase.tufts.edu)

Greenhouse Gases Environmental Concern: Global warming
Action Taken: Fossil fuel : power plants, vehicles Conservation of forest, planting of trees

Weather and Climate(eo.ucar.edu)
Weather – the specific atmospheric conditions that exist at a particular place at a particular time
- controlled by changes in air pressure Example: low pressure: clear skies
high pressure: cloudy skies (rain)
Climate – behavior of atmosphere over a long period of time
- differs in regions of the world:
> amount of sunlight
> geographic factor: proximity to oceans, altitude

Solar Energy and Temperature Regulation

![Page 8: Ecosystem Services of the Atmosphere By: Carlos Antonio Guanzon 8-Mandela.](https://reader036.fdocuments.in/reader036/viewer/2022062906/5a4d1b1d7f8b9ab059994007/html5/thumbnails/8.jpg)
Solar Energy and Temperature Regulation
Solar Energy:
30% reflected back to space
20% absorbed by greenhouse gases and re-radiated to earth’s surface
50% absorbed by earth’s surface
Temperature of Earth:
Normal: 15° C/ 59° F
w/o Greenhouse gases: -18° C/ 0° F (*32° F freezing point)
w/o solar energy reflected: +250° F (212° F boiling point)
* based on moon’s temp (reflecting only 10% solar energy)

Protection from Meteors
• Atmosphere (mesosphere) burns meteors before they hit the surface of the Earth
• Meteors travel fast causing the atmospheric gases to compress quickly
• Generate great amounts of heat, burning the objects
• temperatures can reach as high as 3,000 degrees Fahrenheit (1650 degrees Celsius)
