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 …

Abstract Advances in Earth Observation (EO) technology, particularly over the last two
decades, have shown that soil moisture content (SMC) can be measured to some degree or …

Abstract Information about the spatiotemporal variability of soil moisture is critical for many
purposes, including monitoring of hydrologic extremes, irrigation scheduling, and prediction …

Core Ideas Satellites, particularly at L‐band frequency, can globally map near‐surface soil
moisture. Near‐surface moisture is extended to the root zone using models and data …

In this study we evaluate the skill of a new, merged soil moisture product (ECV_SM) that has
been developed in the framework of the European Space Agency's Water Cycle Multi …

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 …

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 …

Soil moisture (SM) is a key state variable in understanding the climate system through its
control on the land surface energy, water budget partitioning, and the carbon cycle …

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 …
