Abstract. Tropospheric trace gas and aerosol pollutants have adverse effects on health, environment climate. In order to quantify mitigate such effects, a wide range of processes leading the formation transport must be considered, understood represented in numerical models. Regional scale pollution episodes result from combination several factors: high emissions (from anthropogenic or natural sources), stagnant meteorological conditions, kinetics efficiency chemistry deposition. All these...
The Scanning Imaging Absorption Spectrometer for Atmospheric Cartography (SCIAMACHY) satellite spectrometer provides detailed information on the nitrogen dioxide (NO 2 ) content in planetary boundary layer. NO tropospheric column retrievals of SCIAMACHY and its predecessor Global Ozone Monitoring Experiment are characterized by errors order 40%. We present here a new retrieval data set year 2003. cloud free observations compared to surface measurements simulations over western Europe...
The 2008 European Air Quality Directive (AQD) (2008/50/EC) encourages the use of models in combination with monitoring a range applications. It also requires Member States to design appropriate air quality plans for zones where does not comply AQD limit values. In order cope these various elements, wide different modeling methods have been developed and applied by EU last decade assess effects local regional emission abatement policy options on human health. However, an overall review...
A 1D Canopy Interface Model (CIM) is developed to act as an interface between a meso-scale and micro-scale atmospheric model better resolve the surface turbulent fluxes in urban canopy layer. new discretisation proposed solve TKE equation finding solutions that remain fully concordant with layer theories for neutral flows over flat surfaces. correction added buoyancy term of improve consistency Monin-Obukhov theory. Obstacles varying heights dimensions are taken into account by introducing...
Sewage Treatment Plants (STPs) are essential infrastructure for addressing climate change, preserving aquatic ecosystems, and enabling sustainable energy transitions. Traditionally focused on meeting regulatory standards by removing pollutants, modern STPs have transformed into multifaceted systems capable of tackling environmental challenges through resource recovery, generation, emissions reduction. This evolution positions as integral components the circular economy broader action...
The characteristics of indoor light (intensity, spectral, spatial distribution) originating from outdoors have been studied using experimental and modeling tools. They are influenced by many parameters such as building location, meteorological conditions, the type window. a direct impact on air quality through change in chemical processes varying photolysis rates pollutants. Transmittances different windows measured exhibit wavelength cutoffs, thus influencing potential species to be...
OH and HO2 profiles measured in a real environment have been compared to the results of INCA-Indoor model improve our understanding indoor chemistry. Significant levels both radicals their display similar diurnal behavior, reaching peak concentrations during direct sunlight (up 1.6×106 4.0×107 cm-3 for , respectively). Concentrations O3 NOx volatile organic compounds (VOCs), HONO, photolysis frequencies were constrained observed values. The HOx are well simulated terms variation species...
A statistical interpolation method is evaluated for routine production of ozone three‐dimensional fields over western Europe. These are used initializing short‐term forecasts issued from a chemistry‐transport model. We mainly address two questions: (1) To what extent can the use surface observation data improve description relative to raw simulations? (2) Does analysis troposphere's chemical composition? The consists combining simulations with measurements. resulting analyses compared...
The assessment of VOC emission rates and sorption coefficients was performed for ten surfaces present within a classroom, using field laboratory cells (FLEC) coupled to online off-line quantification techniques. A total 21 identified VOCs were emitted by the different surfaces. measured PTR-ToF-MS compared gas chromatographic measurements. results showed that two methods are complementary one another. Sorption parameters also successfully mixture 14 few hours (<17 per surface). study spatial...
The bottom-up traffic emission model EMISENS is used to calculate hourly black carbon (BC) and nitrogen oxides (NOx) rates on an average workday in Maribor (Slovenia), using factors that were previously determined with the on-road chasing measurements Slovenia. From modeled NOx in-situ we empirically dispersion of emissions applied it BC concentrations rates. We compared concentration over three periods winters 2011–2012 2012–2013, a total 67 workdays. Measured first apportioned top-down...
We present a description, an evaluation, and comparison of four methods designed to produce objective physically consistent maps ozone concentration fields. These are based on the use chemistry‐transport model (CTM) available observations. In most existing analysis systems, error covariance is modeled using assumptions homogeneity isotropy. However, these may fail in case strongly heterogeneous terrain or emission patterns. Therefore we propose simple method for specifying anisotropic...
The photolysis of HONO has been found to be the oxidation driver through OH formation in indoor air measurement campaign SURFin, an extensive carried out July 2012 a classroom Marseille. In this study, INCA-Indoor model is used evaluate different mechanisms that have previously quality models. order avoid biases results due uncertainty rate constants, those parameters were adjusted fit one representative day SURFin campaign. Then, tested with optimized against other experiments during Based...
