Estimating root zone soil moisture from AMSR2 remotely sensed surface soil moisture data

Significance of root zone soil moisture can be observed in agricultural practices and meteorological phenomenon and estimation of the same become vital. There is always a correlation between surface and root zone soil moisture and thus a relationship between satellite soil moisture, ground measured soil moisture and modelled soil moisture is investigated here. An R
²
of ~0.5 and ~0.73 is noted between the Soil Water Index (SWI), derived from AMSR2 data, ground data and GLDAS-NOAH modelled soil moisture data. The analysis is performed for IIT Kanpur for the year 2013.
