Progress of satellite remote sensing inversion method for soil moisture
In the context of global warming,soil moisture is a key factor affecting climate drought,crop growth,and environmental change.Using remote sensing technology to estimate soil moisture not only enhances drought early warning capabilities but also holds significant implications for agricultural development,ecological protection,and restoration.This article summarizes the currently used remote sensing data for soil moisture inversion and analyzes its development trends.It elaborates in detail on the principles,advan-tages,and disadvantages of each inversion method from optical and active-passive microwave perspectives,and further explores four main areas of soil moisture research:active-passive microwave,multisource data fusion,spatial scale conversion,and methods and model improvements.Finally,it outlines the evolutionary trends of remote sensing technology in the field of soil moisture inversion and presents a future outlook.
