Layer cloud amounts for the months of January and July 1979 have been extracted from a compressed version of the US Air Force's 3D-nephanalysis. It seems likely that some high level cloud has been incorrectly archived as middle level cloud as a result of: 1) the assumption of cloud emissivities of one in the retrival algorithms and 2) the latitudinally-invariant definition of the middle/high cloud boundary. There is a reasonable level of agreement between zonally averaged low level and total cloud amounts derived here and those of London. West coast stratus is correctly identified as low cloud but the polar cloud amounts exhibit a seasonal cycle opposite to that seen in traditional climatolologies.-from Author
