Isla de calor urbano e incremento de temperatura en vias urbanas en Huancayo/Perú

The rapid urbanization of cities is changing the local climate, resulting in high temperatures and dense, difficult urban environments, lacking water and vegetation [1]. The present contribution estimates the intensity of the Surface Urban Heat Island (SUHI) during the period 2001-2022 for the Huancayo Metropolitan Area (AMH), Peru. The formation of the Surface Urban Heat Island (SUHI) was quantified using 2 methods: the first is the Streutker method, which adjusts the surface soil temperature (LST) (urban and rural surface) to a Gaussian surface. The second, quantile method proposed by José Flores, uses the difference between the 0.95 quantile of LST of the urban area and the median of the LST of the rural area. Both methods use LST remote sensing data at 0.05⁰ resolution, obtained from the MODIS sensor onboard the TERRA and AQUA satellite. For the AMH, during the daytime periods, the intensity of SUHI in March and July represent the maximum and minimum increase. The night period presented maximum and minimum values in August and December respectively. In general, it was possible to show the main causes of the increase in surface temperature is the asphalt pavement, where the temperature can be up to 60 ⁰C. Therefore, it is important to propose mitigation measures such as sustainable constructions and pavements that help mitigate the increase in surface temperature. As well as the importance of considering the Forest or vegetable plantations in an urban design or zoning.
