aU is wind component; LE, H, and SHF represent latent, sensible, and soil heat flux, respectively; Ta, Ts,, and Tc denote air, surface, and above-canopy temperature, in order; RH stands for relative humidity; Rn is net radiation; SoilTC and Hydra_V represent soil temperature and probe's voltage.
bHeights varied typically year-by-year, site-by-site, and in summer/winter period, and are above-ground measurements.
cDenotes measurements of same variable at different locations.
