... the LCZ scheme for the study area, as said by Oliveira et al. (2020), Lisbon's urban fabric is mostly mid-rise within municipal boundaries where morphological parameters such as H/W or Z0 tend to have low spatial variations except for large public or green spaces. In Fig. 2 a representation of Lisbon's LCZ is presented. It should be noted that according to Oliveira et al. (2020), there are 12 different LCZs in Lisbon. Urban LCZs account for more than 645 m 2 and non-urban for more than 3468 m 2 , so 15,7% and 84,3%, respectively. Although Urban LCZs only represent 15.7% of the total Lisbon Metropolitan ...

... the highest and minimum LST were seen in LCZ Bare Soil or Sand. The non-urban LCZ Bare Soil or Sand reported the highest LST for the winter thermal period (Fig. 19) Except for the winter thermal period in LCZ Scattered Tres, Bush Scrubs, Bare Rock or Paved and Water, differences for the average mean LST were always positive in all non-urban LCZ (Figs. 20-23). The differences in the minimum mean LST for the non-urban LCZs were consistently positive over the spring and autumn thermal periods. The biggest differences -always greater than 8 °C -occurred in the spring. Except for LCZ Water, all LCZ display negative difference values during the winter thermal ...

... the exoatmospheric albedo values for the non-urban LCZ (Figs. 24-27), there is not much variation between thermal periods, being the obtained values very similar in all of them. For the Spring Thermal period, when compared to the Summer one it is visible that, although very similar, some differences can be found. These can be seen in the maximum values that are obtained, for example, for the LCZ of ...

... This class was mainly found in the northern part of the city, where the urban area begins and where the historic center is concentrated, as shown in Figure 10. The LCZ 6-Low-rise Open was the most common urban type in Santarém, a conclusion also reached by [41] in Japan and [46] in Lisbon, Portugal, with the majority of the population residing in these areas. This class is characterized by mixed land use, with medium-and high-standard residential areas and simpler constructions. ...

Urban elements influence atmospheric flow, turbulence, and the local microclimate, modifying the transport and composition of pollutants. However, although this focus on cities is crucial for managing climate change, our knowledge of most cities in the world is still quite limited. Thus, the classification of Local Climate Zones (LCZs) aims to increase the accuracy of urban studies and has already been applied in various regions of the world, including, more recently, in Brazil. This article aimed to apply the LCZ to Santarém, a city in the Brazilian Amazon. The methodological procedures included the digital mapping protocol of the World Urban Database and Access Portal Tools (WUDAPT-Level 0) and the supervised classification tool of the LCZ Generator application, resulting in 78 polygons representing 10.02% of the training area and 13.94% of the study area (urban zone). The research identified 7 of the 17 main LCZ classes in Santarém. The use of the NDVI was essential for assessing the vegetation in each class, highlighting variations in green areas and emphasizing that vegetation is reduced in built environments. This approach enhances the understanding of urban morphology and enables future research into urbanization and the climate in the Amazon.
