soil moisture

Soil moisture analysis is widely used in numerous practical cases, from weather forecasts to precise agriculture.  Recently, availability of moisture data increased due to the rapid development of satellite image processing.  However, satellite retrievals mostly provide low-resolution surface data.  In this study, we attempt to retrieve surface soil moisture on the field scale using a decomposition algorithm.  Furthermore, we add a mathematical model based on Richards equation to evaluate soil moisture in the root zone.  To combine the results of both models, we employ a nudging data assimi

The purpose of the research is to establish experimentally the most favorable conditions for determining the vertical movements of the Earth's surface in terms of the minimal influence of variations of soil moisture on the results of observations. Geodetic monitoring of deformation processes at geodynamic testing grounds (GTG) occurs mainly without taking into account the influence of factors on the dynamics of the Earth's surface and benchmarks.
