young ice YI, FY ice, and MY ice as shown by the labels. The color bar denotes the concentration percentage and
the gray color denotes open water. This is a sample product from a set of daily ice concentrations from September
to May in seven ice seasons (2002-2009). (For color detail, please see color plate section).

which is not shown when using AMSR‐E only. The MY
ice drifted from the Arctic basin to the Baffin Bay
through Nares Strait on 14 January 2007. Its presence is
verified in the CIS ice weekly chart for 14 January 2007
(Figure 10.17e). The brown area in the CIS chart features
nearly 100% ice concentration, of which 50% - 70% is
identified as MY ice. AMSR‐E observations do not
capture the MY ice (Figure 10.17a). When combined
with the QuikSCAT data (which has more distinct sig-
nature of MY ice as shown in Figure 10.14), the results
show reasonable distribution of MY ice concentration
(Figure 10.17b) ranging around 80% in the north of
