Classification: CPC A  G | IPC A  G

Claim 5:
6. The processor implemented method of claim 1, wherein the vegetation surface soil moisture is estimated based on the following equation:

SMsurface(t)=β0+β1·X1+β2·X2+β3·X3+β4·X4+β5·X5+σ

wherein
SMsurface(t)=soil moisture at time t;
β0=intercept;
β1, β2, β3, β4=regression coefficients;
X1=SMsurface(0), bare soil moisture at time 0;
X2=smp, soil parameter;
X3=wp, weather parameter
X4=cp, Crop parameter;
X5=Indext, index value (e.g. Normalized Difference Vegetation Index
(NDVI), Enhanced Vegetation Index (EVI)) at time t;
σ=residual.
