Campagne de mesures mobiles pour caractériser l’ICU d’été de la ville de Casablanca (Maroc) : premiers résultats

Abstract : The urban heat island (UHI) is a phenomenon referring to the increase in temperature in urban areas that become warmer than the less densely populated rural areas, thus causing thermal discomfort, excess mortality for the vulnerable people, as well as a deterioration of the air’s quality. The present study aims to observe and analyze the UHI of the city of Casablanca using a mobile measurement method, with the help of a meteorological station collecting microclimatic data and a GPS device recording the routes followed, both mounted on a car. Measurement campaigns were carried out on July, 12th, 16th and 17th of 2019 in several areas of the city following previously selected urban transects. The objective was to measure the temperature of the air in different types of urban forms such as the city center, parks and gardens, industrial or commercial zones ... in order to identify the influence of vegetation and aquatic areas. Regarding its intensity, the local UHI is estimated between 2 ° C and 4 ° C during clear weather nights, with a greater intensity in industrial and dense urban areas in the heart of the city.
