This directory contains browse .gif image and data of sea ice age
(MY and FY sea ice) flags derived from QuikSCAT egg images for the
Arctic within the SCP's Arc region.  This data set is described in 

A.M. Swan and D.G. Long, "Multi-Year Arctic Sea Ice Classification 
Using QuikSCAT", IEEE Transactions on Geoscience and Remote Sensing, 
Vol. 50, No. 9, pp. 3317-3326, 2012.

The sea ice age flag data is on the same 4.45 km polar stereographic
grid as QuikSCAT egg enhance resolution SIR images produced by the 
Scatterometer Climate Record Pathfinder.  The resolution of browse
.gif images has been reduced by a factor of two for presentation.

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

Let us know how you are using the data.
