Basic and other measurements of radiation at Concordia Station (2011-03)

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.

备注：相关LR0004文件（详见ftp文件）中指明的方位角（azimuth）与天顶（zenith）区间内，直射辐射受到新建建筑的遮挡，导致该区域的地平线受到影响。即便晴空条件下的直射辐射与总辐射可能受此遮挡影响，散射辐射仍被认定为有效数据。在阴天条件下，所有辐射分量均不受上述遮挡影响。因此，短波辐射（SW）数据未被标记剔除，数据使用者需自行考量该遮挡对总辐射与直射辐射分量的相关影响。
