Variación de la temperatura en relación a la cobertura de tres zonas localizadas en Villavicencio-Meta

Abstract

This project was carried out as a research aid, with the aim of determining the temperature variation with respect to the surface coverage in the zone contiguous (200m) to the stations of the Surveillance and Air Quality Service of Villavicencio (SVCAV); initially, a diagnosis of surface coverage was made from the local climate zone model (ZCL), in which 5 types of surface cover were classified, such as: pavement, scattered trees, bare soil/scrub, buildings and dense trees; Subsequently, using the quantitative research method, the Spearman correlation, the ANOVA variance analysis and the Tukey test were executed from variables measured in the field (air temperature (Ta), surface temperature (Ts), balloon temperature (Tg), wind speed (v)), and the calculation of the mean radiant temperature (TMR). As a result, the Cofrem, Catumare and La Esmeralda stations showed waterproof coverage values of 76.9%, 44.3% and 58% respectively; taking into account the above, the Cofrem station is the area that reaches the highest MRRs with a range between (33.8ºC and 37.1ºC), then the Catumare station with values between (31.4ºC and 36.3ºC), finally the La Esmeralda station presented data between (29.4ºC to 33.5ºC); also, the analysis of variance and the Tukey test showed that the La Esmeralda study area is different from the other study areas. In conclusion, the Cofrem station was found to be the most critical in terms of temperature increase and infrastructure density; In addition, based on the analysis of environmental variables and their correlation, the degree of similarity between stations was evaluated in order to contribute to the results of a macro-project and serve as a guide for the territorial planning of the City.
