Modeling the components of heat and water balance for the land surface of the globe

The effect of uncertainties in precipitation global datasets on the estimates of terrestrial water balance components

“…The obtained results were par tially published in [7,8,18]. The latter two papers are devoted to studying the effect of uncertainties in the input meteorological data and land surface parameters on the global estimates of the components of terrestrial heat and water balances.…”

Application of a technique for scenario prediction of climate change impact on the water balance components of northern river basins

“…The provided vegetation data sets were corrected to eliminate serious discrepancies and errors. Details of the correction, along with the list of vegetation parameters used in the SWAP model can be found in (Gusev et al, 2006b).…”

“…The parameters were adapted for the SWAP model and corrected to some extent to eliminate implausible values and to meet the agreement among themselves and with vegetation parameters (Gusev et al, 2006b).…”

Parameter Optimization for Simulating Runoff from Highlatitude River Basins Using Land Surface Model and Global Data Sets

“…Global one-degree soil datasets included data on sand, clay, silt and organic matter fractions; texture classes (12 soil texture classes according to the classification of US Department of Agriculture (USDA)); depth of active soil column and soil hydrophysical parameters (porosity, field capacity, wilting point, hydraulic conductivity at saturation, saturated matric potential, B-exponent parameter, soil snow-free albedo) for each grid box. First of all, the values of the soil and vegetation parameters were analyzed and checked for consistency (they must be reasonable and in a good agreement with each other) as it was described in Gusev et al (2006b). In so doing, some corrections were performed.…”

“…Different versions of SWAP were detailed in a number of publications (e.g. Gusev & Nasonova 1998, 2003, 2004aGusev et al 2006b). The last version of SWAP treats the following processes: interception of liquid and solid precipitation by vegetation; evaporation, melting and freezing of intercepted precipitation, including refreezing of melt water; formation of snow cover at the forest floor and at the open site during the cold season; partitioning of non-intercepted precipitation or water yield of snow cover between surface runoff and infiltration into a soil; formation of the water balance of aeration zone including transpiration, soil evaporation, water exchange with underneath layers and dynamics of soil water storage; water table dynamics; formation of the heat balance and thermal regime of SVAS; soil freezing and thawing.…”
