The “online” meteorological and chemical transport Weather Research Forecasting/Chemistry (WRF/Chem) model has been implemented over a European domain, run without aerosol‐cloud feedbacks for the year 2007, validated against ground‐based observations. To this end, we integrated Monitoring Evaluation Programme (EMEP) anthropogenic emission inventory into pre‐processor. simulated average temperature shows very small negative bias, relative humidity wind speed are overpredicted by 1.5% (8%) 1.0...
Abstract. CHIMERE is a chemistry-transport model designed for regional atmospheric composition. It can be used at variety of scales from local to continental domains. However, due the design and its historical use as model, major limitations had remained, hampering hemispheric scale, coordinate system transport well missing processes that are important in regions outside Europe. Most these have been removed CHIMERE-2017 version, allowing any region world scale single urban area up with or...
The formulations of tropospheric gas-phase chemistry ("mechanisms") used in the regional-scale chemistry-transport models participating Air Quality Modelling Evaluation International Initiative (AQMEII) Phase 2 are intercompared by means box model studies. Simulations were conducted under idealized meteorological conditions, and results representative mean boundary layer concentrations. Three sets conditions – winter, spring/autumn summer to capture annual variability, similar 3-D...
The calculation of aerosol optical properties from mass is a process subject to uncertainty related necessary assumptions on the treatment chemical species mixing state, density, refractive index, and hygroscopic growth. In framework AQMEII-2 model intercomparison, we used bulk profiles sampled over locations AERONET stations across Europe North America calculate under range common for all models. Several simulations with parameters perturbed within observed values are carried out July 2010...
As a contribution to phase2 of the Air Quality Model Evaluation International Initiative (AQMEII), eight different simulations for year 2010 were performed with WRF-Chem European domain. The four using RADM2 gas-phase chemistry and MADE/SORGAM aerosol module are analyzed in this paper. included degrees aerosol–meteorology feedback, ranging from no effects at all inclusion direct radiative effect as well cloud interactions indirect effect. In addition, modification gas phase solver was...
Air pollution simulations critically depend on the quality of underlying meteorology. In phase 2 Quality Model Evaluation International Initiative (AQMEII-2), thirteen modeling groups from Europe and four North America operating eight different regional coupled chemistry meteorology models participated in a coordinated model evaluation exercise. Each group simulated year 2010 for domain covering either or both. Here were present an operational analysis performance with respect to key...
Abstract. The impact of air pollution on human health and the associated external costs in Europe United States (US) for year 2010 are modeled by a multi-model ensemble regional models frame third phase Air Quality Modelling Evaluation International Initiative (AQMEII3). surface concentrations O3, CO, SO2 PM2.5 used as input to Economic Valuation Pollution (EVA) system calculate resulting impacts from each individual model. Along with base case simulation, additional runs were performed...
Abstract. Through the comparison of several regional-scale chemistry transport modeling systems that simulate meteorology and air quality over European North American continents, this study aims at (i) apportioning error to responsible processes using timescale analysis, (ii) helping detect causes model error, (iii) identifying temporal scales most urgently requiring dedicated investigations. The analysis is conducted within framework third phase Air Quality Model Evaluation International...
Abstract. The CHIMERE chemistry-transport model v2020r1 replaces the v2017r5 version and provides numerous novelties. most important of these is online coupling with Weather Research Forecasting (WRF) meteorological via OASIS3 – Model Coupling Toolkit (MCT) external coupler. can still be used in offline mode; mode enables us to take into account direct indirect effects aerosols on meteorology. This also using parameters sub-hourly time steps. Some new parameterizations are implemented...
This study reviews the top ranked meteorology and chemistry interactions in online coupled models recommended by an experts' survey conducted COST Action EuMetChem examines sensitivity of those during two pollution episodes: Russian forest fires 25 Jul–15 Aug 2010 a Saharan dust transport event from 1 Oct to 31 as part AQMEII phase-2 exercise. Three WRF-Chem model simulations were performed for fire case baseline without any aerosol feedback on meteorology, simulation with direct effects...
Abstract. Chemical and dynamical processes lead to the formation of aerosol layers in upper planetary boundary layer (PBL) above it. Through vertical mixing entrainment into PBL these may contribute ground-level particulate matter (PM); however, date a quantitative assessment such contribution has not been carried out. This study investigates this aspect by combining chemical physical measurements with WRF/Chem (Weather Research Forecasting Chemistry) model simulations. The observations were...
Abstract. The presence of airborne aerosols affects the meteorology as it induces a perturbation in radiation budget, number cloud condensation nuclei and micro-physics. Those effects are difficult to model at regional scale chemistry-transport models usually driven by distinct meteorological or data. In this paper, coupling CHIMERE with WRF using OASIS3-MCT coupler is presented. fields along aerosol optical properties exchanged through high frequency order aerosol–radiation interactions....
Local emissions of Arctic air pollutants and their impacts on climate, ecosystems health are poorly understood. Future increases due to warming or economic drivers may put additional pressures the fragile environment already affected by mid-latitude pollution. Aircraft data were collected, for first time, downwind shipping petroleum extraction facilities in European Arctic. Data analysis reveals discrepancies compared commonly used emission inventories, highlighting missing (e.g. drilling...
The Air Quality Model Evaluation International Initiative (AQMEII) has now reached its second phase which is dedicated to the evaluation of online coupled chemistry-meteorology models. Sixteen modeling groups from Europe and five North America have run regional air quality models simulate year 2010 over one European American domain. MACC re-analysis been used as chemical initial (IC) boundary conditions (BC) by all participating in AQMEII-2. aim present work evaluate along with against a set...

Abstract. Sustained injection of sulfur dioxide (SO2) in the tropical lower stratosphere has been proposed as a climate engineering technique for coming decades. Among several possible environmental side effects, increase deposition deserves additional investigation. In this study we present results from composition–climate coupled model (University L'Aquila Composition-Chemistry Model, ULAQ-CCM) and chemistry-transport (Goddard Earth Observing System Chemistry-Transport GEOS-Chem), assuming...
The indirect effects of aerosol are particularly important over regions where meteorological conditions and content favourable to cloud formation. This was observed during the Intensive Cloud Aerosol Measurement Campaign (IMPACT) (European Integrated project on Climate Air quality Interaction (EUCAARI) project) in Benelux Union May 2008. To better understand this formation variability, have been included within WRF-CHIMERE online model. By comparing model results aircraft measurements...
Abstract The lockdown period (March–May 2020) during the COVID‐19 pandemic in Europe led to a reduction anthropogenic emissions of primary pollutants. For three‐quarters over 1,100 available monitoring stations, average nitrogen dioxide (NO 2 ) concentrations decreased by at least 2.7 μg·m −3 (or 25%) compared with recorded same previous seven years. This was not specific urban or rural areas because relative similar magnitude both areas. ozone (O 3 response differed spatially, positive...
