Sea ice monitoring from space is overviewed. The relationships among the albedo of the earth, hydrology cycle, ocean dynamics, atmospheric physics/ dynamics, sea ice, in-land ice, open water and polynya are introduced together with the brief, descriptions of the basic principles for microwave radiometer, scatterometer, synthetic aperture radar, laser atmospheric sounder/altimeter, visible and near infrared radiometer. Further sea ice monitoring in the Earth Observing System (EOS) Program including the background and the plan for experiments is also introduced.
