QuikSCAT Sea Ice Age (MY/FY)
Daily maps of classified Arctic sea ice indicating whether it is
first-year (FY) or multi-year (MY) derived from QuikSCAT data.
The product is generated on standard SCP polar stereographic grid
for the Arc region coresponding to QuikSCAT egg (quev or queh)
images. This data product is described in the paper below.
Note that the resolution of browse .gif images has been reduced
by a factor of two. Data can be accessed from the
and the web page.
This product is primarily designed to map MY ice. The ocean/sea ice edge is low resolution since it is determined from the AMSR 6 GHz channel (see reference). The flag values stored in the SIR array are:
-2 : no data
-1 : land
0 : ocean
1 : first year (FY) ice
2 : multi year (MY) ice
