Soil moisture map construction using microwave remote sensors and sequential data assimilation

no code implementations28 Sep 2020 Bernard T. Agyeman, Song Bo, Soumya R. Sahoo, Xunyuan Yin, Jinfeng Liu, Sirish L. Shah

Secondly, measurements obtained from the microwave sensors are assimilated into the field model using the extended Kalman filter to form an information fusion system, which will provide frequent soil moisture estimates and predictions in the form of moisture content maps.
