“…In opposite to this, Clement and Ford (1999a) considered the uncertainty in the sticking probability as the main problem in defining the growth rate. The authors argued: "There appeared recently to be a theoretical and experimental consensus that sticking probabilities for water and sulphuric acid on liquid droplets are small (Itoh, 1990;Van Dingenen and Raes, 1991 (Clement et al, 1996). Direct experiments on growing droplets of n-propanol/water mixtures give results consistent with S p =1, the theoretically most likely value for all except very light atoms or molecules on dense materials at normal temperatures.…”

“…To consider turbulent density fluctuations, the governing equations for the first-, second-and third-order moments must be rederived on the base of a scale analysis (Bernhardt, 1964(Bernhardt, , 1972Bernhardt and Piazena, 1988;Foken, 1989;Venkatram, 1993;van Dop, 1998). In the subsequent Papers II and III, the model capability to predict the CBL evolution in terms of first-, second-and third-order moments and to simulate the evolution of UCNs during a NPF event will be demonstrated within the framework of a conceptual study.…”

Abstract.A high-order modelling approach to interpret "continental-type" particle formation bursts in the anthropogenically influenced convective boundary layer (CBL) is proposed. The model considers third-order closure for planetary boundary layer turbulence, sulphur and ammonia chemistry as well as aerosol dynamics. In Paper I of four papers, previous observations of ultrafine particle evolution are reviewed, model equations are derived, the model setup for a conceptual study on binary and ternary homogeneous nucleation is defined and shortcomings of process parameterisation are discussed. In the subsequent Papers II, III and IV simulation results, obtained within the framework of a conceptual study on the CBL evolution and new particle formation (NPF), will be presented and compared with observational findings.

“…There is considerable uncertainty in the magnitude of a e . Van Dingenen and Raes (1991) report values of a e in the range of 0.02 to 0.1. The theoretical studies of Clement et al (1996) and the field measurements of Weber et al (1995) report values of a e close to unity.…”

A global off-line model of size-resolved aerosol microphysics: II. Identification of key uncertainties

Abstract. We use the new GLOMAP model of global aerosol microphysics to investigate the sensitivity of modelled sulfate and sea salt aerosol properties to uncertainties in the driving microphysical processes and compare these uncertainties with those associated with aerosol and precursor gas emissions. Overall, we conclude that uncertainties in microphysical processes have a larger effect on global sulfate and sea salt derived condensation nuclei (CN) and cloud condensation nuclei (CCN) concentrations than uncertainties in present-day sulfur emissions. Our simulations suggest that uncertainties in predicted sulfate and sea salt CCN abundances due to poorly constrained microphysical processes are likely to be of a similar magnitude to long-term changes in sulfate and sea salt CCN due to changes in anthropogenic emissions. A microphysical treatment of the global sulfate aerosol allows the uncertainty in climate-relevant aerosol properties to be attributed to specific processes in a way that has not been possible with simpler aerosol schemes. In particular we conclude that: (1) changes in the binary H 2 SO 4 -H 2 O nucleation rate and condensation rate of gaseous H 2 SO 4 cause a shift in the vertical location of the upper tropospheric CN layer by as much as 3 km, while the shape of the CN profile is essentially pre-served (2) uncertainties in the binary H 2 SO 4 -H 2 O nucleation rate have a relatively insignificant effect on marine boundary layer (MBL) aerosol properties; (3) emitting a fraction of anthropogenic SO 2 as particulates (to represent production of sulfate particles in power plant plumes below the scale of the model grid (which is of the order of 300 km)) has the potential to change the global mean MBL sulfate-derived CN concentrations by up to 72%, and changes of up to a factor 20 can occur in polluted continental regions; (4) predicted global mean MBL sulfate and sea salt CCN concentrations change by 10 to 60% when several microphysical processes are changed within reasonable uncerCorrespondence to: D. V. Spracklen (dominick@env.leeds.ac.uk) tainty ranges; (5) sulfate and sea salt derived CCN concentrations are particularly sensitive to primary particle emissions, with global mean MBL sulfate and sea salt CCN changing by up to 27% and local concentrations over continental regions changing by more than 100% when the percentage of anthropogenic SO 2 emitted as particulates is changed from 0 to 5%; (6) large changes in sea spray flux have insignificant effects on global sulfate aerosol except when the mass accommodation coefficient of sulfuric acid on the salt particles is set unrealistically low.

“…Note that a wide range of values for α H 2 SO 4 has been derived from measurements (0.02-0.79; e.g. Van Dingenen and Raes, 1991;Kerminen and Wexler, 1995;Jefferson et al, 1997;Bardouki et al, 2003) and used in models (0.1-1; e.g. Vignati et al, 2004;Zaveri et al, 2008;Mann et al, 2010;Kajino et al, 2012).…”

The MESSy aerosol submodel MADE3 (v2.0b): description and a box model test

et al. 2014

Abstract. We introduce MADE3 (Modal Aerosol Dynamics model for Europe, adapted for global applications, 3rd generation; version: MADE3v2.0b), an aerosol dynamics submodel for application within the MESSy framework (Modular Earth Submodel System). MADE3 builds on the predecessor aerosol submodels MADE and MADE-in. Its main new features are the explicit representation of coarse mode particle interactions both with other particles and with condensable gases, and the inclusion of hydrochloric acid (HCl) / chloride (Cl) partitioning between the gas and condensed phases. The aerosol size distribution is represented in the new submodel as a superposition of nine lognormal modes: one for fully soluble particles, one for insoluble particles, and one for mixed particles in each of three size ranges (Aitken, accumulation, and coarse mode size ranges).In order to assess the performance of MADE3 we compare it to its predecessor MADE and to the much more detailed particle-resolved aerosol model PartMC-MOSAIC in a box model simulation of an idealised marine boundary layer test case. MADE3 and MADE results are very similar, except in the coarse mode, where the aerosol is dominated by sea spray particles. Cl is reduced in MADE3 with respect to MADE due to the HCl / Cl partitioning that leads to Cl removal from the sea spray aerosol in our test case. Additionally, the aerosol nitrate concentration is higher in MADE3 due to the condensation of nitric acid on coarse mode particles. MADE3 and PartMC-MOSAIC show substantial differences in the fine particle size distributions (sizes 2 µm) that could be relevant when simulating climate effects on a global scale. Nevertheless, the agreement between MADE3 and PartMC-MOSAIC is very good when it comes to coarse particle size distributions (sizes 2 µm), and also in terms of aerosol composition. Considering these results and the well-established ability of MADE in reproducing observed aerosol loadings and composition, MADE3 seems suitable for application within a global model.
