METHODSWe constructed a portable electronic nose equipped with four different MOx gas sensors (SGX Sensortech MiCS5914 & MiCS4514 dual sensor, ScioSense CCS801) and recorded the natural olfactory scenes encountered during a walk through the city of Lisbon, Portugal, dividing the dataset into six geographical locations (hereafter labelled’Taxi’,’Supermarket’,’Graça’,’Baixa’,’Seashore’, and’Santos’). We sampled the conductance of the gas sensing elements at 1 kHz while modulating the heater power with a period of 140 ms, each heater cycle consisting of a high-power step followed by a low-power step. This causes the sensor conductance to oscillate in a way that depends on the heater temperature, the environmental conditions, and the gases present in the sensor cavity (fig. 1).
