Global Cloud Climatologies: A Historical Review

摘要: Abstract Accurate global cloud information is required for many climate studies, particularly validation of model simulations. This paper reviews the climatologies currently available, identifying and attempting to explain differences between various assessments. The two types observations used construct a climatology, conventional surface satellite-derived observations, are contrasted. Meridional profiles zonally-averaged total amount geographic distribution from 17 data sets compared. There at present no unique and/or agreed climatology. review emphasizes uncertainty inaccuracies associated with knowledge distribution. Cloud constructed either or satellite will not be identical. range available current must noted by all users globa...
