FIG. 1. Image showing dual-probe heat-pulse (DPHP) sensor locations at Plots (A) CW1 and (B) CW4. Solid circles are DPHP sensors; white boxes are 107 thermistor probes installed at 0-cm depth; triangles are water content reflectometers; hatched boxes are locations of multiplexers and enclosures. Insets show an example of a DPHP sensor installed at the ground surface and a schematic of sensor orientation.
