Focus Topic: Spatial–Temporal Dynamics of Soil Moisture

Soil moisture is a highly spatially and temporally variable parameter. This focus topic addresses techniques and methods to characterize and predict spatial variability of soil moisture across scales, analysis of soil moisture patterns using theoretical and numerical modeling approaches, and upscaling of sparsely measured soil moisture content at point or farm scale up to catchment scale. This focus topic features original, basic, and applied studies on spatial–temporal dynamics of soil moisture at various scales.
