Temperature variations for the urbanization perimeters of the smallest municipalities 2020-2022

Map illustrating the differences in relative surface temperatures for all small urban areas in Quebec. The relative temperature difference is the temperature difference in the city compared to a nearby wooded area.

With a 9-level scale for classifying relative differences in temperature, this map indicates areas that are relatively cooler or warmer within urbanization perimeters. This map is complementary to the * [map of urban heat/fresh islands (ICFU)] (https://www.donneesquebec.ca/recherche/dataset/ilots-de-chaleur-fraicheur-urbains-et-ecarts-de-temperature-relatifs-2020-2022) *. In fact, it covers all areas of urbanization that are not (or only partially) covered by the ICFU card. Thus, the two maps placed side by side allow a complete coverage of all population centers and urbanization perimeters in Quebec.

The interval values for each class of temperature difference within the urbanization perimeters also come from the ICFU map: the classification thresholds for the temperature differences of an urbanization perimeter are reproduced from those of the ICFU map for the population center closest to the urbanization perimeter.

The production of this data was carried out by the National Institute of Public Health of Quebec (INSPQ) and was funded under the * [Plan for a Green Economy] (https://www.quebec.ca/gouvernement/politiques-orientations/plan-economie-verte) * of the Government of Quebec. This third party metadata element was translated using an automated translation tool (Amazon Translate).
