Microclimatic conditions in Ingá Park – Maringá (Paraná, Brazil) according to air humidity parameters

Abstract

The complexity of measuring water in its different physical states stems partially from inaccurate recording instruments and limited climatic parameters. As atmospheric composition is variable, researchers use several indexes to describe one of its elements, water vapor. The present research estimates air humidity in Ingá Park, in Maringá city, Paraná State, Brazil. For that, we used relative humidity data obtained from a temperature and humidity recorder inserted in the park. The data refer to the period from April 2019 to January 2020 and from June 2020 to March 2021. We also used remote sensing to verify the amount of precipitable water vapor over the same area in the available time interval of MSI/Sentinel 2A images. Ingá Park has the potential to improve beneficial effects to the city, especially considering the relative humidity and the condition of faster saturation of that observation station. According to the analysis of orbital images, precipitable water vapor in the park was 26,298 mm in 2019 and 25,950 mm in 2020, with a reduction in the first six months in the period from 2019 to 2021. Water vapor estimation through orbital images corroborated the data measured by the fixed sensor. Although these measurements are not equivalent, the study showed a decreasing dynamics of air humidity.
