      abstract     = {Soil moisture is an important state variable in the
                      terrestrial system because it controls the exchange of water
                      and energy between the land surface and the atmosphere. In
                      this study, we review recent advances in noninvasive
                      techniques that allow continuous noninvasive and contactless
                      measurements of soil moisture dynamics at the field to basin
                      scale. In particular, we report on (1) cosmic-ray neutron
                      probes, (2) Global Navigation Satellite System
                      reflectometry, (3) ground-based microwave radiometry, (4)
                      gamma-ray monitoring, (5) terrestrial gravimetry, and (6)
                      low-frequency electromagnetic surface waves. Each method is
                      described in terms of its basic principle, measurement
                      scales, calibration issues, measurement accuracy, and
                      applications. We hope that this review will further
                      stimulate the community to invest in the continued
                      development of novel soil moisture sensing methods that
                      address the need for large-scale soil water content
                      measurements with sufficiently high temporal resolution.
