Cloud distribution characteristics at Mizuho Station, Antarctica are discussed. The transmittance of the direct solar radiation and downward longwave radiation are used as an index of clouds.

The direct solar beam transmittance is a good indicator of clouds in the sunlit season. The downward longwave radiation varies sensitively according to the cloud.
