Spectral analysis of plant environmental temperatures. (a) Calculation of thermal spectral irradiance. Spectral irradiance of plant environmental temperatures in a range of 4 °C to 37 °C was calculated according to the Planck’s law of blackbody radiation. Solar radiation was included in the analysis for comparison. The calculation values were plotted against wavelength. The X-axis is represented in a logarithmic scale. (b) Peak wavelength of spectral irradiance. The peak wavelength and maximal spectral irradiance values were obtained from the spectral calculations in (a).
