The surface radiative temperature (emissivity: 1.0) was measured by the automatic thermometer at intervals of 0.05s, and the data were archived as .txt files (.dat format). The first seven rows were the header file, including acquisition date, time, and intervals; besides, Time (starting time), TObj (target temperature), Tint (the interior temperature of the probe), TBox (the temperature of the box) and Tact (the actual temperature calculated from the given emissivity) were also listed.
Soil moisture (0-12cm and 0-20cm) was measured by TDR. The data including the soil temperature, soil complex permittivity and soil conductivity, were archived in Excel format.
