Based on surface temperature, humidity and wind data collected from 77 points over a period of eight days in and around Madras using mobile surveys, the heat island characteristics at Madras have been assessed. The maximum heat island intensity is seen to be about 4°C. The humidity pattern apart from showing maritime influence also indicates a minimum over the heat pocket. The mixing height is found to be more over urban area than over rural area indicating lower pollution potential over the former due to the mixing over a larger depth than in the latter.
