Introduction to Topic
- Atmosphere and its role in heating of the Earth
- What is forcing the climate?
- The sun
- It affects multiple terrains differently
- Ocean absorbs energy before reflecting back
- Dark so absorbs more than grass or snow
- Mountain reflects off the light
- Albedo averages (% reflected)
- Earth’s albedo average (31%)
- Grass 25-30%
- Fresh snow 80-95%
- Forests 10-20%
- Crops, grasslands 10-25%
- Asphalt 5-10%
- Concrete 1727%
- Brick, stone 20-40%
- Light roof 35-50%
- Dark roof 8-18%
- Water bodies 10-60%
- The atmosphere is the thin blue region along the edge of the earth
- Very shallow layer
- The Atmosphere-Ocean Climate System
- The Climate System (very complicated)

- Clouds, volcanic ash, particles (aerosols) all interfere with how much of the
energy we can get
- The Atmosphere is characterized by
- Vertical structure
- Temperature change from surface all the way up
- Wind speed
- Air pressure
- Constituents
- Atmospheric composition
- Atmospheric moisture
- Variable gas
- Water vapor
- Gas laws
- Laws that govern the behavior of gas
- The role of atmosphere in heating of the earth
- Atmospheric layers
- Atmouspheric omposition
- Important atmospheric greenhouse gases
- Effect of atmospheric composition on Earth’s temperature
- Main layer of the atmosphere
- Troposphere, stratosphere, mesosphere, thermosphere
- Tropopause, stratopause, mesopause
-
- Why does the graph change its mind, increase, decrease
- Important to know this chart (one from textbook)
- Atmosphere
- Thin film
of gaseous mixtures
- In the vertical, more than 99% of mass found below 30km
- Horizontal dimensions may be represented by distance between poles (20,000
km); if proportion preserved, thickness of atmosphere on an office globe- a coat
of paint
- Yet-atmosphere-central component of climate system
- Shallow, but very important for climate
- Main layers of atmosphere
- Troposphere, stratosphere, mesosphere, thermosphere
- Separated by conceptual partitions-called pauses
- Uniform composition
