Refresh rate and spatial coverage are key requirements • New generation of GEO imagers (ABI/GOES-R, FCI/MTG, AHI/Himawari) – 15 min full disk – 1-5 min regional subsets • Cloud tracking => improved wind retrievals • Improved surface observations due to collecting all possible clear-sky pixels • Resolving diurnal cycle of clouds, radiation, snow/ice cover dynamics Page 8 – February 7, 2011
Improved clear-sky statistics due to high temporal frequency (1-day model data for July 1, 2008) Start: July 1, 2008 3:00UT Daily mean cloud fraction : 69% (64%) Mean cloud fraction after clear-sky compositing : (every 15min over 24hrs) 34% (32%) (50 0 N-90 0 N) Initial clear-sky mask Accumulated clear-sky mask after 24hrs clear cloud Page 9 – February 7, 2011
