Special Issue Information

Dear Colleagues,

The measure of actual evapotranspiration is necessary to grasp the dynamics of water flows on the Earth’s surface. It is not possible to obtain it by difference between inflows and outflows because of the great uncertainty that would ensue. Traditionally it has been obtained mainly in agricultural applications as a correction of the values of potential evapotranspiration. Today there are tools that allow reliable estimates from the scale of the individual plant to the footprint of micrometeorological instruments, both in the agricultural and natural field. In addition, satellite data allow inference over large areas.

In the case of surface areas on land, the problems associated with the unevenness of evaporating surfaces and vegetation must be solved. For remote sensing there are problems to match the spatial detail to the temporal one. A great effort of experimental research has been made, as well as in modeling. Many research groups are validating such models and at the same time experimental measurements are being refined. By combining modelling with measurements, it is time to provide reliable assessments at territorial scale for practical applications such as estimating the recharge of aquifers for drinking and irrigation management.

The objective of this issue is to take stock of the different measurement and modelling methodologies and how synergies can be brought together.

The article discusses the features of large-scale spatial and temporal variability of moistening (potential evapotranspiration, precipitation, potential evapotranspiration coefficient) in the Siberian part of Russia for the period 1981–2015. The All-Russian Research Institute of Hydrometeorological Information—World Data Center (RIHMI-WDC) archive has served as a source of initial information. Due to the rare network of stationary meteorological stations in most of Siberia, only 32 stations located mainly in the valleys of large rivers have been used for calculations. To estimate potential evapotranspiration, the modified method of M.I. Budyko has been used. A comprehensive delimitation of Siberia has been carried out by the interannual fluctuations of characteristics of moistening, being well divided into four regions, three of which encompass the basins of the largest rivers: the Ob, the Yenisei, the Lena and the fourth region represents the Baikal region. Analysis of the trends shows that the evapotranspiration in Siberia is growing only in the Ob basin and the Baikal region. Precipitation, excluding the Baikal region, is also increasing in the Yenisei and Lena basins. As for the potential evapotranspiration coefficient, a significant trend refers only to the Baikal region due to the rapid increase in evaporation. The modeling of the annual values of the characteristics of moistening for the selected regions has been carried out using the decision trees method. For 4-branch trees, the coefficient of determination R2 describes about two-thirds of the variance of the original variable (0.57–0.73). In the models of annual evapotranspiration values, the main predictor is the air temperature. In precipitation models, the contribution of local and external circulation factors to interannual precipitation fluctuations is equal. Full article
