In this section, the 5 used algorithms to retrieve ice concentration will be
outlined.
Most algorithms are based on two simple equations:
where 
, 
and 
are the amount of open
water, multi-year ice and first-year ice, respectively.
is not to be confused with 
from equation 1. The second formula is:
where 
is the brightness
temperature and 
, 
and 
are the brightness
temperatures from open water, multi-year ice and first-year ice, respectively.
The algorithms will be addressed separately below.
