In the past, cloud-cover has been a major factor limiting the use of remote sensing for
hydrological applications. Satellites such as ERS-1, which carry microwave sensors, can …

Remote sensing has begun to have an impact on applied hydrology as well as hydrologic
research. Because remote sensing is basically spatial information it is providing a new form …

Remote sensing has a great, but largely unfilled, potential to provide valuable information for
hydrologic analysis. The two primary characteristics that make remote sensing a potentially …

Microwave remote sensing offers emerging capabilities to monitor global hydrological
processes. Instruments like the two dedicated soil moisture missions SMOS and HYDROS or …

Abstract The “Electronic Age” offers new and attractive opportunities to hydrologists for
remote sensing (RS) of hydrological data. A discussion of hydrologically relevant platforms …

Physical principles governing passive microwave remote sensing of hydrological variables
are outlined and illustrated by actual observations by ground-based, air-borne and space …

Microwave remote sensing at L-band (21 cm wavelength) can provide a direct measurement
of the surface soil moisture for a range of cover conditions and within reasonable error …

Passive and active microwave remote sensing instruments are capable of measuring the
surface soil moisture (0–5 cm) and can be implemented on high altitude platforms, eg …

Soil moisture is one of the few directly observable hydrological variables that has an
important role in water and energy budgets necessary for climate studies. At the present time …

The development of microwave sensors and the research on their application to the study of
hydrologic problems has proceeded rapidly in the last few years. There are two primary …
