Only a combination of various techniques and a multi-plan approach can provide a remote information system for studying soil moisture. This approach is characterized by principles of multizonality, multiple-scale, multiple-time, and congruity. The multizonality of remote soil moisture determination consists of a simultaneous survey of the soil surface in various regions of the electromagnetic reflection and emission spectrum. Study of the moisture field of the earth's surface on a multiple scale requires a combination of general small-scale and detailed large-scale space and aerial surveys. Multiple-time remote aerospace surveys of soil moisture are achieved by repeated surveys of the earth by meteorological and natural resources satelites with different frequency. The congruity of a remote space survey consists of performing synchronous or quasisynchronous soil moisture measurements by various information systems: at ground-based research and automatic stations, on individual traverses and in selected areas by aircraft and spacecraft.
