A review of homogenization techniques for climate data and their applicability to precipitation series

During the last decades, a considerable effort was spent on the development of homogenization techniques that can identify and correct anthropogenic bias in climatic series. These methods were developed in various countries, for different contexts and for different domains of applicability. The present paper is an exhaustive review of published homogenization techniques for climatic series. A critical analysis of the described methods and a discussion on their applicability to total annual precipitation are also presented.
