Abstract
This contribution estimates the Intensity of Surface Urban Heat Island (SUHI) during the period 2001–2016 for the Metropolitan Areas of Cairo (CMA), Johannesburg (JMA), and Lagos (LMA), located in Africa. To quantify the SUHI, two methods were used: the Gaussian method, and the Quantiles method. Both methods use monthly surface temperature (ST) remote sensing data and annual land cover type product at 0,05° resolution, obtained from the MODe-rate resolution Imaging Spectroradiometer (MODIS) sensor on board the TERRA and AQUA satellites. In the results obtained for the Gaussian method, the maximum daytime IICUS occurred in the AML with 4.82 °C and the minimum in the AML with 0.01 °C. At night, the maximum found was in AMC with 4.64 °C and the minimum in AMJ with 1.30 °C. For the Quantiles method, the maximum monthly daytime IICUS is found in the AML is 5.78 °C and the minimum in the AMC is-1.56 °C. At night, the maximum IICUS was at AMC with 4.88 °C and minimum at AML with 2.05 °C.
