Estimation of soil moisture content by remote sensing methods: A review

Author(s):

Abstract:
Understanding the spatial and temporal variations of soil moisture is crucial for the land surface processes and their management. The soil moisture content in the surface layers of the soil is an important parameter for many applications in hydrology, horticulture, geotechnical, agriculture and meteorology. Hence accurate estimation of spatial and temporal variation in soil moisture content is important. Recently, remote sensing techniques have been used to estimate soil moisture. Estimation of soil moisture by remote sensing techniques provides only surface layer information and is unable to observe the entire soil column. On the other hand field measurement provide valuable information regarding both surface and subsurface soil moisture, but are insufficient to characterize the spatial and temporal variability of soil moisture at larger scale. Therefore, remote sensing methods have an edge over field methods in terms of spatial and temporal scale. This paper presents a comprehensive review of the progress in remote sensing or soil moisture studies.
