  Abstract: Various postulations on the relationship between urban morphology and air quality are qualitative. This fails to establish the strength of the contributions of each morphological parameter in the spatial distribution of the air quality. It is this gap in knowledge that this study sought to fill by modelling the correlation existing between the urban morphological... More

  Abstract: Urban air quality degradation from rising CO₂ is acute in rapidly developing tropical cities such as Makassar, Indonesia. We deploy a drone-based Internet of Things (IoT) platform for real-time CO₂ monitoring, integrating low-cost sensors (NDIR, MQ135, MG811) on a DJI Phantom 4 with cloud streaming to Firebase. Measurements were collected at five sites, namely Jl.... More
