Abstract
Abstract. Aerosol formation acts as a sink for gas-phase
atmospheric species that controls their atmospheric lifetime and
environmental effects. To investigate aerosol formation and evolution in the
Netherlands, a hybrid positive matrix factorization (PMF) analysis was
conducted using observations from May, June, and September 2021 collected in
the rural site of Cabauw in the central part of the Netherlands. The hybrid input matrix
consists of the full organic mass spectrum acquired from a time-of-flight
aerosol chemical speciation monitor (ToF-ACSM), ACSM inorganic species
concentrations, and binned particle size distribution concentrations from a
scanning mobility particle sizer (SMPS). These hybrid PMF analyses discerned
four factors that describe aerosol composition variations: two size-driven
factors that are related to new particle formation (NPF) and growth (F4 and
F3), as well as two bulk factors driven by composition, not size (F2 and F1). The
distribution of chemical species across these factors shows that different
compounds are responsible for nucleation and growth of new particles. The
smallest-diameter size factor (F4) contains ammonium sulfate and organics
and typically peaks during the daytime. Newly formed particles, represented
by F4, are mainly correlated with wind from the southwesterly–westerly and
easterly sectors that transport sulfur oxides (SOx), ammonia
(NH3), and organic precursors to Cabauw. As the particles grow from F4
to F3 and to bulk factors, nitrate and organics play an increasing role, and
the particle loading diurnal cycle shifts from daytime to a nighttime
maximum. Greater organics availability makes secondary organic aerosol (SOA)
more influential in summertime aerosol growth, principally due to volatility
differences produced by seasonal variation in photooxidation and
temperature.
期刊介绍：
Atmospheric Chemistry and Physics (ACP) is a not-for-profit international scientific journal dedicated to the publication and public discussion of high-quality studies investigating the Earth''s atmosphere and the underlying chemical and physical processes. It covers the altitude range from the land and ocean surface up to the turbopause, including the troposphere, stratosphere, and mesosphere.
The main subject areas comprise atmospheric modelling, field measurements, remote sensing, and laboratory studies of gases, aerosols, clouds and precipitation, isotopes, radiation, dynamics, biosphere interactions, and hydrosphere interactions. The journal scope is focused on studies with general implications for atmospheric science rather than investigations that are primarily of local or technical interest.
