A schematic overview of the ELBARA-III tower setup (top panel) and the footprints (bottom panel). The footprints vary from 3.31 m2 to 43.64 m2 for incidence angle from 40° to 70°. The half-axes of the elliptic footprint are indicated as a and b for a given incidence angle \({\theta }_{i}\) (top panel) and the projected ground distances from the radiometer to the closest- and the farthest-side of the elliptic footprints at −3 dB sensitivity of the antenna are indicated as dmin and dmax (bottom panel). The locations of the installed in situ soil moisture and soil temperature sensors are indicated as SMST_Z and SMST_LC. The fence (25 m × 45 m) is not drawn to scale.
