What are the disadvantages of atmosphere?
Drawbacks
- The atmosphere holds in some “greenhouse” gases that retain the heat of the Sun.
- Clouds regularly obscure good astronomical viewing.
- The atmosphere refracts light which means the position and clarity of star viewing is less accurate.
- Pollution from light and chemicals obscure observations.
