Comprehensive modelling study on observed new particle formation at the SORPES station in Nanjing, China
New particle formation (NPF) has been investigated intensively during the last 2 decades because of its influence on aerosol population and the possible contribution to cloud condensation nuclei. However, intensive measurements and modelling activities on this topic in urban metropolitan areas i...

description |
New particle formation (NPF) has been investigated intensively during the
last 2 decades because of its influence on aerosol population and the
possible contribution to cloud condensation nuclei. However, intensive
measurements and modelling activities on this topic in urban metropolitan
areas in China with frequent high-pollution episodes are still very limited.
This study provides results from a comprehensive modelling study on the
occurrence of NPF events in the western part of the Yangtze River Delta (YRD)
region, China. The comprehensive modelling system, which combines the
WRF-Chem (the Weather Research and Forecasting model coupled with Chemistry)
regional chemical transport model and the MALTE-BOX sectional box model (the
model to predict new aerosol formation in the lower troposphere), was shown
to be capable of simulating atmospheric nucleation and subsequent growth.
Here we present a detailed discussion of three typical NPF days, during which
the measured air masses were notably influenced by either anthropogenic
activities, biogenic emissions, or mixed ocean and continental sources.
Overall, simulated NPF events were generally in good agreement with the
corresponding measurements, enabling us to get further insights into NPF
processes in the YRD region. Based on the simulations, we conclude that
biogenic organic compounds, particularly monoterpenes, play an essential role
in the initial condensational growth of newly formed clusters through their
low-volatility oxidation products. Although some uncertainties remain in this
modelling system, this method provides a possibility to better understand
particle formation and growth processes. |
