The European Space Agency's Climate Change Initiative for Soil Moisture (ESA CCI SM)
merging algorithm generates consistent quality-controlled long-term (1978–2018) climate data …

To date, triple collocation (TC) analysis is one of the most important methods for the global-scale
evaluation of remotely sensed soil moisture data sets. In this study we review existing …

We propose a method for merging soil moisture retrievals from spaceborne active and
passive microwave instruments based on weighted averaging taking into account the error …

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 of in …

Climate Data Records of soil moisture are fundamental for improving our understanding of
long-term dynamics in the coupled water, energy, and carbon cycles over land. To respond to …

The International Soil Moisture Network (ISMN) was initiated in 2009 to support calibration
and validation of remote sensing products and land surface models, and to facilitate studying …

In 2009, the International Soil Moisture Network (ISMN) was initiated as a community effort,
funded by the European Space Agency, to serve as a centralised data hosting facility for …

Soil moisture observations are of broad scientific interest and practical value for a wide range
of applications. The scientific community has made significant progress in estimating soil …

Global soil moisture records are essential for studying the role of hydrologic processes within
the larger earth system. Various studies have shown the benefit of assimilating satellite‐…

In situ soil moisture measurements play a key role for a variety of large‐scale applications.
A deep understanding of their quality, especially in terms of spatial representativeness, is …
