1. MERRA fractional sea ice fields These fractional sea ice fields were computed from the hourly FRSEAICE field. The movies show the time evolution of 1-day of fractional sea ice data. Activate the slide show option slide show (F5 key) to see movies. SEAICE00: Fraction of each grid box having < 10% sea ice coverage SEAICE10: Fraction of each grid box having 10-20% sea ice coverage SEAICE20: Fraction of each grid box having 20-30% sea ice coverage SEAICE30: Fraction of each grid box having 30-40% sea ice coverage SEAICE40: Fraction of each grid box having 40-50% sea ice coverage SEAICE50: Fraction of each grid box having 50-60% sea ice coverage SEAICE60: Fraction of each grid box having 60-70% sea ice coverage SEAICE70: Fraction of each grid box having 70-80% sea ice coverage SEAICE80: Fraction of each grid box having 80-90% sea ice coverage SEAICE90: Fraction of each grid box having > 90% sea ice coverage For a given grid box (I,J) the sum of: SEAICE00(I,J) + SEAICE10(I,J) + SEAICE20(I,J) + SEAICE30(I,J) + SEAICE40(I,J) + SEAICE50(I,J) + SEAICE60(I,J) + SEAICE70(I,J) + SEAICE80(I,J) + SEAICE90(I,J) = 1.
