MOESM3 of Controlled infrared heating of an artic meadow: challenge in the vegetation establishment stage

Additional file 3. Theoretical thermal radiation distribution uniformity over a heated plot (i.e. angle factor) as determined in Kimbal et al. (2012) for 2 different heaters height (Z) and tilt angle (θ) [8]. On the upper part of the graph intensity of thermal radiation over the heated plot is presented on the vertical axis. On the lower part of the graphic the intensity of thermal radiation is presented on a color scale ranging from red/low temperature to white/high temperature. Small dots represent heaters positions. The large black circle represent the area in which is calculated the relative range [(maximum-minimum)/mean] and the coefficient of variation CV. The left setting was selected for this experiment
