Ao ar livre e à própria sorte: avaliação térmohigrométrica e morfologica de espaços abertos vegetados em Fortaleza (Ceará)

Abstract

This case study analyzes thermohygrometric variability and thermal comfort in two green urban spaces in Fortaleza: an urban garden in Lagoa Redonda and an incidental vegetated plot at the UFC’s Institute of Physical Education and Sports. The research examines surrounding morphology, land use, and microclimatic parameters obtained through remote sensing and field data. SAVI (Soil-Adjusted Vegetation Index) and LST (Land Surface Temperature), GOES 10 satellite data, and the “Fortaleza em Mapas” platform were used. Hourly air temperature and relative humidity data were collected and analyzed using the heat index. Results show that both sites are informally used and disconnected from environmental policies. The incidental space is a residual green area in a high-density zone, while the garden is part of a green corridor in a low-density area. Dense native vegetation around the garden served as a thermal and humidity regulator, stabilizing moisture and reducing heat peaks. In contrast, the incidental site’s sparse vegetation and impermeable ground intensified thermal and hygrometric discomfort.
