“…In the actual work, the universal function for heat H,(z−d)/L as published by Businger (1966) was integrated with the method of Dyer and Hicks (1970) for the unstable case. For the stable case the universal function for heat as published by Webb (1970) was used (see Supplement). The flux of a scalar, which is equal to u * · χ * , can be deduced from Eq.…”

“…This site, operated by INRA (Institut National de la Recherche Agronomique) and hosted by AgroParisTech, was part of the EC CarboEurope-IP, NitroEurope-IP, Eclaire-IP and INGOS-IP European projects and is part of the ICOS and Fluxnet measurement networks. The site is well documented (Laville et al, 2009;Loubet et al, 2011) as are several experiments on reactive trace gases performed at the site (Bedos et al, 2010;Loubet et al, 2012Loubet et al, , 2013Potier et al, 2015;Personne et al, 2015;Wu et al, 2016;Vuolo et al, 2017). Briefly, measurements were carried out on a 19 ha field with a fetch of 100-400 m depending on wind direction.…”

“…These results stimulated laboratory investigations on potential HONO precursors from which the most frequently discussed mechanisms are (i) the photosensitized reduction of nitrogen dioxide (NO 2 ) by organic material, e.g. humic acids (George et al, 2005;Stemmler et al, 2006;2007, Sosedova et al, 2011Han et al, 2016), (ii) the photolysis of adsorbed nitric acid (Zhou et al, , 2011Laufs and Kleffmann, 2016), (iii) biogenic production of nitrite in soil (Su et al, 2011;Ostwald et al, 2013;Maljanen et al, 2013;Oswald et al, 2015;Scharko et al, 2015;Weber, 2015) and (iv) release of adsorbed HONO from soil surfaces after deposition of strong acids (VandenBoer et al, 2013(VandenBoer et al, , 2014(VandenBoer et al, , 2015Donaldson et al, 2014). Another discussed source, the reaction of excited gaseous NO 2 with water (Li et al, 2008), is of minor importance as demonstrated by laboratory (Crowley and Carl, 1997;Carr et al, 2009;Amedro et al, 2011) and modelling studies (Sörgel et al, 2011b;Czader et al, 2012).…”

Abstract. Nitrous acid (HONO) fluxes were measured above an agricultural field site near Paris during different seasons. Above bare soil, different crops were measured using the aerodynamic gradient (AG) method. Two LOPAPs (LOng Path Absorption Photometer) were used to determine the HONO gradients between two heights. During daytime mainly positive HONO fluxes were observed, which showed strong correlation with the product of the NO 2 concentration and the long wavelength UV light intensity, expressed by the photolysis frequency J (NO 2 ). These results are consistent with HONO formation by photosensitized heterogeneous conversion of NO 2 on soil surfaces as observed in recent laboratory studies. An additional influence of the soil temperature on the HONO flux can be explained by the temperature-dependent HONO adsorption on the soil surface. A parameterization of the HONO flux at this location with NO 2 concentration, J (NO 2 ), soil temperature and humidity fits reasonably well all flux observations at this location.

“…The contribution of NO-NO 2 -O 3 chemistry to observed ozone fluxes can be estimated with ozone, NO, and NO 2 fluxes at two heights (Finco et al, 2018;Fitzjarrald & Lenschow, 1983;Lenschow & Delany, 1987;Vilá-Guerau de Arellano et al, 1993). An empirical technique only requiring flux measurements at one height has also been used (e.g., Plake, Sörgel, et al, 2015;Stella et al, 2012;Vuolo et al, 2017). This empirical technique assumes flux divergences of NO, NO 2 , and ozone are logarithmic with height, but the theoretical basis for this assumption is lacking.…”

Dry deposition of ozone is an important sink of ozone in near‐surface air. When dry deposition occurs through plant stomata, ozone can injure the plant, altering water and carbon cycling and reducing crop yields. Quantifying both stomatal and nonstomatal uptake accurately is relevant for understanding ozone's impact on human health as an air pollutant and on climate as a potent short‐lived greenhouse gas and primary control on the removal of several reactive greenhouse gases and air pollutants. Robust ozone dry deposition estimates require knowledge of the relative importance of individual deposition pathways, but spatiotemporal variability in nonstomatal deposition is poorly understood. Here we integrate understanding of ozone deposition processes by synthesizing research from fields such as atmospheric chemistry, ecology, and meteorology. We critically review methods for measurements and modeling, highlighting the empiricism that underpins modeling and thus the interpretation of observations. Our unprecedented synthesis of knowledge on deposition pathways, particularly soil and leaf cuticles, reveals process understanding not yet included in widely used models. If coordinated with short‐term field intensives, laboratory studies, and mechanistic modeling, measurements from a few long‐term sites would bridge the molecular to ecosystem scales necessary to establish the relative importance of individual deposition pathways and the extent to which they vary in space and time. Our recommended approaches seek to close knowledge gaps that currently limit quantifying the impact of ozone dry deposition on air quality, ecosystems, and climate.

“…Mechanisms behind the chemical quenching at the soil surface are not completely understood but findings from several flux partitioning studies emphasized the soil as an important sink for O 3 in forests (Lamaud et al, 2002;Dorsey et al, 2004;Fares et al, 2014;Zhou et al, 2017) as well in ecosystems with smooth surfaces (Sanchez et al, 1997;Meszaros et al, 2009;Stella et al, 2013). The fact that low ground water levels favored O 3 uptake suggested that the depth or soil volume available for O 3 to diffuse in the soil pores constituted a limiting factor for uptake in the soil Vuolo et al, 2017). A laboratory study, conducted by Sorimachi and Sakamoto (2007) on Chinese soil samples revealed that there was only a small impact of geometric surface area or soil weight on υ d .…”

A 10-year long dataset of half-hourly ozone (O 3 ) fluxes was used to study the variability in deposition velocity (υ d ) over a mixed temperate suburban forest. Average (median) υ d amounted to 0.70 (0.46) cm s −1 , with day-and night-time average (median) of 0.98 (0.73) cm s −1 and 0.46 (0.30) cm s −1 , respectively. It was found that the precipitation form had a marked impact on υ d and the deposition efficiency (υ d/ υ dmax ), with highest values measured when the canopy was dew-wetted or covered with snow. The analysis further evidenced that traffic volume led to increased deposition due to the presence of chemical reactions between O 3 and nitric oxide (NO) above the canopy surface. During the working week, daytime values of υ d, υ d/ υ dmax and the O 3 fluxes (F) were found to be significantly higher than the weekend values, especially during the winter half-year. In a next step, half hourly deposition data were aggregated into day-and night-time monthly values, for a correlative study with measured environmental variables. Monthly average night-time/daytime υ d and υ d/ υ dmax were positively correlated with the relative humidity at the canopy surface (RH(z 0 ′ )) and negatively correlated with the water levels below the ground surface. During the daytime, monthly υ d and υ d/ υ dmax were additionally increased during the working-week when traffic volume was high. There existed, however, substantially different weather conditions, in which unaccounted covariates with a totally different meteorological signature controlled the υ d and F. It was speculated that, among other, biogenic volatile compounds (BVOCs) could have contributed to O 3 quenching in some (spring) months with severe drought stress.
