Soil moisture (SM) is a key hydrologic state variable that is of significant importance for
numerous Earth and environmental science applications that directly impact the global …

Observations from spaceborne radar contain considerable information about vegetation
dynamics. The ability to extract this information could lead to improved soil moisture …

Soil moisture map** at a high spatial resolution is very important for several applications
in hydrology, agriculture and risk assessment. With the arrival of the free Sentinel data at …

Drought is a major cause of limited agricultural productivity and of crop yield uncertainty
throughout the world. For that reason, agricultural drought research and monitoring are of …

Many physical, chemical and biological processes taking place at the land surface are
strongly influenced by the amount of water stored within the upper soil layers. Therefore …

ERA-Interim/Land is a global land surface reanalysis data set covering the period 1979–
2010. It describes the evolution of soil moisture, soil temperature and snowpack. ERA …

In situ measurements of soil moisture are invaluable for calibrating and validating land
surface models and satellite-based soil moisture retrievals. In addition, long-term time series …

A series of satellite-based passive and active microwave instruments provide soil moisture
retrievals spanning altogether more than three decades. This offers the opportunity to …

Global soil moisture products retrieved from various remote sensing sensors are becoming
readily available with a nearly daily temporal resolution. Active and passive microwave …

We explore and review the value of soil moisture measurements in vadose zone hydrology
with a focus on the field and catchment scales. This review is motivated by the increasing …
