Abstract: Continuous CO2 concentrations have been monitored at various land-use types by means of fixed stations, short-term spatial sampling, and car traverses using closed-path infrared gas analyzers to characterize and study the temporal and spatial patterns of near-surface CO2 concentrations in Singapore. The methodology is supplemented by intra-urban and -rural sampling which aims to investigate the spatial variability of CO2 that may arise due to site-specific characteristics within both land-use types. Relationship between CO2 concentration and traffic, and other meteorological variables is sought and analyzed over diurnal, monthly and seasonal time scales. The results observed can be understood in terms of the extent of urbanization and associated anthropogenic activities (largely traffic), the vegetation fraction and the role of meteorological variables in modulating the magnitude of CO2 concentration observed at the study sites. Results of the present study are consistent with most of the findings observed in mid-latitude cities.
