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. This paper presents a comprehensive description and benchmark evaluation of the tropospheric gas-phase chemistry component Multiscale Online Nonhydrostatic AtmospheRe CHemistry model (NMMB-MONARCH), formerly known as NMMB/BSC-CTM, that can be run on both regional global domains. Here, we provide an extensive annual cycle simulation using variety background surface stations (EMEP, WDCGG CASTNET), ozonesondes (WOUDC, CMD SHADOZ), aircraft data (MOZAIC several campaigns), satellite...
Atmospheric chemists have recently focused on the relevance of NO 2 * + H O → OH HONO reaction to local air quality. This chemistry has been considered not relevant for troposphere from known rates until nowadays. New experiments suggested a rate constant 1.7 × 10 −13 cm 3 molecule −1 s , which is an order magnitude faster than previously estimated upper limit 1.2 −14 determined by Crowley and Carl (1997). Using new global model, NMMB/BSC Chemical Transport Model (NMMB/BSC‐CTM), simulations...

Much effort devoted to mitigating air leading significant reduction primary pollutants emissions from 2013 2017, while continuously worsening trend surface ozone (O 3 , secondary pollutant and greenhouse gas) was observed same period. Atmospheric oxidation, dominated by daytime reactions involving hydroxyl radicals (OH), is critical process convert freshly‐emitted compounds...
Severe and persistent haze events in northern China, characterized by high loading of fine aerosol especially secondary origin, negatively impact human health the welfare ecosystems. However, current knowledge cannot fully explain formation this pollution. Despite field observations elevated levels reactive halogen species (e.g., BrCl, ClNO2, Cl2, HBr) at several sites influence halogens (particularly bromine) on pollution is largely unknown. Here, for first time, we compile an emission...

Abstract The rigorous traffic limitations during COVID-19 have forced many people to work from home, reaching an outstanding degree of teleworking and reduction in air pollution. This exceptional situation can be examined as a large-scale pilot test determine the potential improving urban quality through teleworking. Based on observed reductions lockdown Barcelona, we formulate socio-occupational scenarios, with various configurations teleworking, simulate them using chemistry transport...
Tropospheric reactive bromine is important for atmospheric chemistry, regional air pollution, and global climate. Previous studies have reported measurements of species in different environments, proposed their main sources, e.g. sea-salt aerosol (SSA), oceanic biogenic activity, polar snow/ice, volcanoes. Typhoons other strong cyclonic activities (e.g. hurricanes) induce abrupt changes earth system processes, causing widespread destructive effects. However, the role typhoons regulating...
Abstract Heat and drought events are increasing in frequency intensity, posing significant risks to natural agricultural ecosystems with uncertain effects on the net ecosystem CO 2 exchange (NEE). The current Vegetation Photosynthesis Respiration Model (VPRM) was adjusted include soil moisture impacts gross (GEE) respiration ( R ECO ) fluxes assess temporal variability of NEE over south‐western Europe for 2001–2022. Warming temperatures lengthen growing seasons, causing an increase GEE,...
Cities are hot spots on greenhouse gas (GHG) emissions, yet green infrastructure (GI) such as spaces and parks provides potential solution for reducing urban carbon footprints through photosynthetic uptake sequestration. Studies have shown that the offset of vegetation local anthropogenic CO2 emissions varies between 2% 100%, underscoring complexity associated with this solution. Quantifying CO2 capture by GI is challenging due to interplay respiration, seasonal variability,...
Terrestrial ecosystems play a crucial role in mitigating climate change by reducing greenhouse gas (GHG) emissions and sequestering significant amounts of atmospheric carbon dioxide (CO2). Wetlands, particularly coastal wetlands, are highly efficient sinks but can also be large sources methane (CH4). Natural agricultural such as rice paddies, contribute to 37 % global CH4 emissions. Monitoring wetland-atmosphere exchange is essential evaluate the effectiveness natural solutions (NCS),...

Monitoring CO2 concentrations in urban areas is crucial for determining the efficacy of climate change mitigation policies. However, highly heterogeneous land use, local geography, and convection patterns, which vary throughout landscape, complicate this task. To establish continuous monitoring programs, it important to first determine heterogeneity landscapes on ground. understand role these factors play distribution over an area, we conducted a measurement campaign Metropolitan Area...
