An Optimization Scheme of Instrumental Soil Water Storage Determination

V. A. Dolgii-Trach

An optimization scheme is considered of the method of instrumental determination of soil moisture used within the Roshydromet system. The scheme enables to reduce the volume of instrumental operations by 2.5–3 times using the empirical statistical dependences between the water content in different layers of the soil profile. Efficiency of the filtration of outliers in the data sample is studied on the basis of the analysis of regression residuals when deriving the regression equations.
