Basic and other measurements of radiation at Concordia Station (2011-08)

Note: the horizon was affected by a new building that creates obstruction for direct radiation in the range of azimuth and zenith indicated in the relevant LR0004 (see ftp file). Whether direct and global radiation were affected in clear-sky condition, the diffuse was considered to be valid. Under overcast all components can be considered unaffected. Hence, SW data were not flagged out and is a responsibility of data user to take into account relevant effects to global and direct components.
