A ground-based microwave scatterometer was installed on an alpine meadow over the Tibetan Plateau to study the soil moisture and -temperature dynamics of the top soil layer and air-to-soil interface during the period August 2017 - July 2019. The radar return (amplitude and phase) of the ground surface was measured over 1 - 10 GHz in the four linear polarization combinations (vv, hh, hv, vh) at hourly or half-hourly intervals .
This dataset contains both the (raw) radar return values (amplitude and phase) and the backscattering coefficients derived from it (vv and hh only). Included are results from the time-series measurements over the period August 2017 - August 2018 and results of experiments (during three days in summer) where the ground backscatter was measured under various incidence- and azimuth angles. Also measurement results from calibration standards are included.
Finally, In-situ measurement results of the volumetric soil moisture and soil temperature (at various depths) and precipitation for the complete period are added to this dataset.
