Characteristic temperature of the lower atmosphere

Ocean skin temperature

Bulk temperature of near-surface ocean

10-12 m

3.5 - 4.1 m

Often the relative atmospheric transmission is plotted vs. increasing wavelength

10-12 m3.5-4.1 m

1 m 2 m

Absorption coefficient for pure water as a function of wavelength λ of the radiation.

Depth range that contributes to 11 m IR Depth range

that contributes to 10 GHz microwave radiometer

(a) Strong winds (b) Day-time weak winds

Why is the skin temperature always biased cool?
