Dear Natural Capital community,

I would like to better understand some of the results provided by the model urban cooling.

Fist, what is exactly the average temperature anomaly provided in the uhi\_results

Second, is there a way to transform the “cooling capacity index” (CC) into degrees?, I would like to know how the patches I am analyzing are contributing with the regulation of the temperature in degrees.

Thanks in advanced.  
Alberto

Hi @Albegonz , good questions.

I think you are referring to the value reported in the `uhi_results.shp` output. This is the average air temperature within the polygon (from `T_air.tif`), minus the “reference air temperature” value.

I think this question of getting results in terms of actual temperature change may be addressed in this thread. It sounds like the CC index is not appropriate for this, but a scenario-based approach using the `T_air` outputs might be.

> Hi, I am running the cooling model for my case study area and planning to use the results to find out supply demand mismatches. For the analysis I would need a map with temperature reduction in avoided heat (in degrees Celsius) due to green infrastructure. If I understand it correctly, the cooling model results give Tair and Tnomix but none of them is showing the avoided heat? I have checked the user guide but I was not able to figure out how this could be done. Is there any way to get this fro…

This is another great thread on what the CC index can tell you:

> I have read the relevant sections of the user guide (Interpreting Results, and the Model explanation) but I still have a question regarding CC. Is it essentially the amount of heat mitigation that is being done in that pixel based on albedo, shade, and ET, but not including green area effects? Where 1 would be full heat mitigation and 0 would be no mitigation? And is it accurate to present the data like a percent? So, for example, if a pixel has a CC of 0.35, could you say that ~35% of the hea…
