Recommended assumptions in the calculation the meteo-based 187 TSIs for practicality or when no data are available.
| ID | Assumption | Value | Assumption |
|---|---|---|---|
| 1 | We calculated wind at altitude using a friction coefficient for “high crops, hedges and shrubs”. [166] | α = 0.20 |  |
| 2 | We set a standard value for workers’ body stature. [167] | Height = 1.80 m |  |
| 3 | We set a standard value for workers’ body mass. [168] | Weight = 75 kg |  |
| 4 | We assume a comfortable barometric pressure (sea level). [169] | P = 1016 hPa |  |
| 5 | Mean skin temperature was estimated as a function of air temperature. [112] | Tsk = f (Ta) |  |
| 6 | We set a constant emissivity of the body / clothing. [167] | ε = 0.97 |  |
| 7 | We set a constant effective radiating area of the body (standing posture). [167] | Ar = 0.77 |  |
| 8 | We assume a constant core temperature. This can be modified as needed. | Tcr = 37.3 |  |
| 9 | Clothing insulation was estimated as a function of air temperature. | Icl = f (Ta) |  |
