Animation of the QuikSCAT scatterometer-derived Arctic sea ice classification v1.0 from 20 June 2002 through 23 November 2009. The dataset provides nominal 4.45 km (pixel resolution at reference latitude 70 N) gridded fields that classify First-Year (FY) and Multi-Year (MY) sea ice using SeaWinds on QuikSCAT scatterometer observations on a daily basis. First-Year sea ice is defined as ice that has formed only during that specific year. Multi-Year sea ice is defined as the winter-time ice that survives the summer melt season.
