Análisis del comportamiento de la temperatura del aire, la humedad relativa y la velocidad del viento y su relación con el arbolado urbano presente en tres zonas de Villavicencio

Abstract

This work is presented in the form of Research Aid within the framework of the FODEIN research project of the Faculty of Environmental Engineering, entitled as "Analysis of the ecosystem service of temperature regulation in the urban microclimate that is supplied by the woodland in three areas of Villavicencio" which seeks to recognize the importance of the presence of urban woodland in outdoor public spaces in the municipality of Villavicencio (Arboleda & Bustamante, 2019). This Research Support made contributions to Phase II (items 1, 2, 6 and 7) and Phase III (items 3 and 5) of the FODEIN project in mention, in addition it contributes with an additional environmental indicator to those raised in the project mentioned. With the interest of identifying the variation between air temperature, wind speed and relative humidity, three phases were proposed that formed the specific objectives of the same. Data were initially obtained from the Catumare, Cofrem and La Esmeralda stations, whose time series were completed for each variable mentioned with the missing data estimation methods of the normal and inverse ratio at distance (IDW) in the time range from 6 a.m. to 17 p.m. The behavior of the anomalous data expressed in graphs of maxima and minima was studied and culminated with the effective temperature calculation, relative and absolute abundance with the inventory data of the urban woodland of the Secretary of Environment of the municipality of Villavicencio to conclude with thermal maps that zoned the areas. The results indicate the presence of the La Niña phenomenon in 2018 and the El Niño phenomenon in 2019 in the three seasons, and the area with the greatest reduction in effective temperature taking into account the most representative species was La Esmeralda. that obtained a maximum effective temperature reduction of 2.07 due to the presence of species such as yopo and cedar, which conclude that the greater the height and circumference at chest height, the greater the effective temperature reduction in that season .
