SMAR: Soil moisture analytical relationship

Formulation for the estimation of the soil moisture (SM) in the root zone based on the measured value of SM at the surface

Code for the application of the SMAR model (Manfreda et al., 2014) and its calibration when root-zone soil moisture data are available for parameter calibration.
