Vertical Structure of PM_2.5 and CO₂ Concentrations in The Greater Bandung Air Basin

The Greater Bandung air basin, surrounded by mountains and hills, has a unique topography that could block the horizontal displacement of pollutants. Consequently, pollution in these areas is affected vertical-spread pattern Previous studies identified PM 2.5 CO 2 concentrations Telkom University have similar trend data vertically up to 30 m above ground. Therefore, this study was conducted observe analyze distribution pollutants vertical direction broaden measurement points using drones. A drone chosen considering available high building limited, also minimalize spatial differences. measuring parameters are meteorological conditions (temperature/T, relative humidity/RH, pressure/P). Two different times at day time (August 31, 2019) nighttime (September 30, 2019), altitudes ~80m. During measurements, it indicated change rotor or drone’s propeller speed airflow. Results show there indications deposition morning, which decreases ~20 μg/m 3 after height >40 m. been lifting mixing evenly from afternoon evening, increasing night ~15 . As for , level ~80 altitude do not significant relatively stable change.
