The DPRA Heat Module for the Heat Overlay can be used for heat stress calculations, based on geographical features and locale parameters. The final result is the physiological equivalent temperature, which is a measure of temperature which takes into account factors which can change the experience and effects of temperature.

The module performs these calculations in accordance with the DPRA Heat stress report.

Input factors

The calculation of the Heat Stress Overlays takes into account:

Calculation of Physiological Equivalent Temperature

To calculate the Physiological Equivalent Temperature (PET), we first have to determine which formula (sun or shade/night) should be used. It is selected by:

PET sun

The following factors influence the Physiological Equivalent Temperature for locations directly in the sun:

PET shade and night

The following factors influence the Physiological Equivalent Temperature for locations directly in the shade or at night:
