* UHI (Urban Heat Island effect)
*      Temperature of atmosphere
* Vegetation average
* Vegetation (yes/no))
* Bowen ratio (evaporation ratio): in the city a value of 3 is normal. For green that evaporates well or open water, a value of 0.4 is normal.  
* Wind speed


De  overlays are calculated by our cuda module.
The selectable modules are:
* [[Heat_DPRA_Module|DPRA Heat stress module]]. This module is more detailed and based on the new [[DPRA guideline|Dutch DPRA standards]]. It can generate multiple Heat Overlay [[Result type (Heat Overlay)|result types]] as child overlays;
* Unesco Heat stress module. This module generates a simple heat stress overlay which visualizes the [[Pet_relative_result_type_(Heat_Overlay)|Relative Physiological equivalent temperature]] result type. It uses a different (and smaller) set of formula's to calculate Heat differences. It does not calculate the expected Physiological Equivalent Temperature.

Example of the DPRA heat stress overlay

We are working on a new Heat Stress Overlay module, which will be in accordance with the new Dutch DPRA standards. This module is still under construction, as is the documentation, however a Beta version of the module is available on the Preview server for our partners.

Modules

In order to configure a Heat Stress Overlay, a module has to be selected. The module can be configured by opening the Heat Overlay Wizard.

The selectable modules are:

Example of the UNESCO heat stress overlay


Notes

  • The Heat Stress overlay present in the Climategame uses the UNESCO Heat stress model.
