Structure

Factor: Carbon dioxide (CO₂)
Setting: tour bus cabin, TW
Study design: continuous CO2 and temperature monitoring in the driver and passenger zones of three 43-seat air-conditioned tour buses during a three-day school excursion in Taiwan under real traffic conditions (class 4)
Effect: other 2646.9
Averaging time: maximum daily average
Sample: 3 rooms
Caveat: the CO2 monitor's upper detection limit was 3000 ppm
