We have spent quite a bit of time in class talking about Urban Heat Islands and their different effects, yet it is different to hear about them than to actually see them in a real-time map. This interactive map shows UHI in California calculating temperature differentials over time between urban areas and nearby upwind rural reference points at the height these would be experienced by humans rather than ground level. The map is color-coded according to intensity and the index is reported in degree-hours per day or you can also view the UHI effects through average daily temperature increments.
