Longwave radiation

Exchanged between sky, surface and all surrounding
objects (trees, etc.)

2

The atmosphere is
a _______
in the longwave

selective absorber

3

The most significant
absorbing gases are:

- water vapour (the
most important)
- CO2
- O3
- O2
- N2O
- CH4

4

coldest
nights are...

those with cloudless skies or only high cirrus clouds because cloud has a large effect on and the incoming long waves

5

the surface is usually warmer than the...

atmosphere therefore the net longwave
L* is usually negative

6

why is the Atmosphere somewhat like greenhouse glass?

it is transparent to shortwave but opaque to longwave
radiation

7

Important greenhouse gases:

-H2O
- CO2
- O3
N2O
- CH4
- CFC-11
- CFC-12

8

what is earth's average surface temperature?

~15 degrees

9

what would earth's average surface temperature be without an atmosphere?

~ - 18 degrees

10

The greenhouse effect is worth how much?

~ 33 degrees
