Field scale computer modeling of soil moisture with dynamic nudging assimilation algorithm
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
