From atmospheric- to pedo-climate modeling in Technosols: A global scale approach

It is now certain that soil evolution will be strongly influenced by climate change. In particular, young soils, such as anthropogenic soils, show evolution patterns that change faster than natural soils. They can contain large quantities of organic pollutants (in the context of industrial activities) which mobility in the environment might differ under the impact of several environmental factors, particularly climate. To better quantify the link between climatic fluctuations and their impact on soil properties, it is important to understand how meteorological records can be derived into pedoclimates. Using HYDRUS-1D, we converted fluctuations of water content and temperature into pedoclimatic events over time as a function of climatic conditions, soil properties and depth. First, using data collected from lysimeters and a local weather station, we calibrated the fluctuations in soil water content and soil temperature. The model efficiently predicts the evolution of soil temperature (index of agreement >0.97 and RMSE
