q |
The very strong downward emission of terrestrial
radiation from
|
|
|
the atmosphere is crucial to main the relatively small diurnal
|
|
|
variation of surface temperature.
|
|
|
q |
If this large downward radiation is not larger than solar heating
|
|
|
of the surface, the surface temperature would warm rapidly
|
|
|
during the day and cool rapidly at the night.
|
|
|
č a large diurnal variation of surface temperature.
|
|
|
q |
The greenhouse effect not only keeps Earth’s surface
warm but
|
|
|
also limit the amplitude of the diurnal temperature variation at
|
|
|
the surface.
