Canton tower new particle formation vertical observation dataset in 2020
Description
In-situ measurements of ultrafine particles (UFP) and New particle formation (NPF) observed at the ground and at the top of the Canton Tower (454 m) located in downtown Guangzhou in southern China were analyzed using the measurements of multiple meteorological and physicochemical quantities.

In order to investigate the Particle number size distribution (PNSD), a suite of instruments were operated on the ground and near the top of the Canton (also called Guangzhou) Tower (454 m a.s.l.) in center of a megacity Guangzhou, located in southern China, under the influences of heavy traffic and many other anthropogenic activities. The ground station is located at the Guangzhou Meteorological Bureau, about 9 km south of the tower. Synchronous measurements started on 18 December 2019 when the Nano Scanning Mobility Particle Sizer (SMPS) was placed on the tower platform to measure the size distributions of ultrafine particles (UFP, particle size<100 nm) for comparing with ground data. On 30 January 2020, an Aerosol Chemical Speciation Monitor (ACSM) began collecting upper-air chemical composition data from the tower platform. After 11 February 2020, an aethalometer was installed on the tower measuring black carbon (BC) mass concentrations.
