Investigating the relationship between variation of greenhouse gases concentrations and humidex

Abstract

The increasing greenhouse gases (GHGs) in the atmosphere contribute to increasing average temperature earth’s surface. This research investigated relationship between variation of GHGs and human thermal comfort based on humidity index (humidex). This study applied humidex, an indices to assess the thermal comfort. The analysis was done by examining the observational data from two different monitoring stations in Serpong and Bogor. The result showed that the average CO2 concentration per month ranged between 422 and 453 ppm in Serpong, whereas in Bogor the average CO2 concentration per month was 413-426 ppm. The average CH4 concentration per month variation in Serpong was 2.05-2.65 ppm. While in Bogor, the average CH4 concentration per month variation ranged between 1.92 and 2.08 ppm. The difference of GHGs concentration in each location might be influenced by meteorological parameters and environmental characteristics. The comfort level according to humidex in Serpong was 30.5-41.5 whereas in Bogor was 29.4-38.5. The correlation between GHGs concentration and air temperature in urban areas in both stations showed a significant and strong but negative relationship. The relationship between GHGs concentration and humidex was indirectly indicated by the relationship of GHGs concentration on air temperature as indicator of humidex.

“…Studies (Lewicki et al, 2010;Duo et al, 2018;Afonso & Pires, 2017)have reported the same results. In winter, from Table 2 and Figure 5, the concentrations of CO and CO2 are in an extremely weak and negative correlation with T and decrease with the increase of T. These are in agreement with discussions of studies (Ocak & Turalioglu, 2008;Lewicki et al, 2010;Ma'rufatin & Kusnoputranto, 2018). But O3 has a weak and positive association with T and increased with an increase in T, meaning that the photochemical reaction of ozone seemed to be important in the formation of O3 during the cold season (Duo et al, 2018).…”
