Theoretical questions of daily data homogenization
Tamás Szentimrey · 2013
The so-called variable correction methods form a special type of methods developed for daily data homogenization. Their common assumption is that in case of daily data series, the corrections for inhomogeneity have to vary according to the meteorological situation of each day in order to represent the extremes. In this paper we express our objections to these variable correction methods, especially to their underlying principles. Since the exact theoretical mathematical formulation of the question of daily data homogenization is generally neglected, we also try to formulate and analyze this problem in accordance with mathematical conventions. Key-words: daily data series, homogenization, climate extremes, higher-order moments, distribution, mathematical formulation
