How data was acquired	Metal Oxide (MOX) gas sensors provided by Figaro Inc. placed in a turbulent wind tunnel. Temperature and RH were recorded continuously with SHT15 sensor (Sensirion).
Data format	Raw data. Time-series.
Experimental factors	For each measurement 72 time series corresponding to MOX sensors׳ conductivity are provided. Temperature and humidity are provided in additional time series.
Experimental features	Sensors were exposed to clean air before and after sample presentation to acquire rising/decay transient portions of the signals.
Data source location	San Diego, California, US.
Data accessibility	Data in public repository:
