Instructions:

Select a summer day and adjust the ternary slider to modify the built environment features. Alternatively, upload a fisheye photo for an automated extraction of feature variables. Then, use the slider to indicate surface characteristics by setting the impervious/pervious fraction. Tick the checkbox if the area is shaded and provide an air temperature value. The predicted mean radiant temperature (T_mrt) output is presented below, alongside a hypothetical fisheye photo determined by the inputs provided.

T_mrt has been recognized as the most critical atmospheric metric influencing the human thermal experience T_mrt summarizes the effects of short and longwave fluxes (direct and reflected) on the human body and is an essential indicator of thermal exposure in human biometeorology.
