Figure 16.6: Mean sea surface temperature in °C from AVHRR measurements (top) and
nocturnal bulk versus skin temperature difference in K from A VHRR and SSM/I measurements
(bottom) in August 1987; due to the limited sampling frequency of the SSM/I the boundaries of
single swaths are visible in the lower image. The estimated error of t:,.T is 0.05 K.

Radiation reflected by a flat surface is highly polarized for incidence angles 0 0 < .,' ) < 90 0 • This
is also true for the smooth sea surface. When the surface is roughened by wind stress acting
