| Abstract | Volumetric surface soil moisture content (θ v ) plays an important role in different environmental. Various methods have been developed for quantifying the soil moisture status . Recent technological advances in remote sensing have shown that soil moisture can be measured with a variety of remote sensing techniques, each with its own strengths and weaknesses. In this study, t he trapezoidal relationship between land surface temperature ( LST ) and Vegetation Index (VI) was used to obtain a soil wetness index (SWI), from which θ v was derived, with the combination of dry and wet edges using Landsat 8 satellite data. Besides, t he practical Split - Window algorithm was set up for calculating the LST in the condition that some of atmospheric data are unknown. The capability of using SWI based on LST ∼ VI trapezoid to estimate soil moisture is evaluated using in situ measurement data in a part of Red river delta, Vietnam. These results showed that this approach was well correlated with observed soil moisture, the root mean square error (RMSE) estimates was 0.05 m 3 .m - 3 with a correlation coefficient R 2 = 0.65 . This study suggests that the approach has a potential for operationally monitoring soil moisture conditions o f the field to regional scale areas with restricted data. |
