The BSS GLOBE Club is investigating the differences in the surface temperature of (i) grass, (ii) concrete and (iii) pitch. This is of particular importance to the students of Brazil Village as there have been marked developments in this community over the last 15 years. There is a distinct trend away from the rural life and one towards urbanization. This has been supported by a gradual replacement of the natural vegetation of the community by infrastructural support for the rapidly developing community.
The data collected during the period 2008 to 2014 showed that there were increases in the ambient temperatures of both the concrete and the asphalt surface and a decrease in the ambient temperature of the grass field. The data also showed the ambient temperature of the asphalt was consistently higher than the other two surfaces and that of the grass field consistently lower. It was concluded that these differences in ambient temperature was primarily due to the moisture holding capacity of the surfaces and to some extent the dark coloration of the asphalt.
It was recommended that similar investigations be done at a different time of the year. It was also recommended that the exact moisture capacity of each surface be quantified and compared. Finally, a detailed description of the extent of urbanization in Brazil Village was suggested, to determine its effect on the microclimate of the community.
