Arctic tropospheric ozone: assessment of current knowledge and model performance
Jakob Boyd Pernov, Luca Pozzoli, Ilann Ernest Valentin Bourgeois
As the third most important greenhouse gas (GHG) after carbon dioxide (CO2) and methane (CH4), tropospheric ozone (O3) is also an air pollutant causing damage to human health and ecosystems. This study brings together recent research on observations and mo ...
2023Assessment of personal exposure to particle and gaseous air pollutants in residences and offices
Maria Viviana Gonzalez Serrano
Poor indoor air quality has been associated with health issues and decreased work performance. Personal exposure that takes place both in outdoor and indoor environments is the result of dy-namic processes and complex interactions between people and surrou ...
EPFL2023Human personal air pollution clouds in a naturally ventilated office during the COVID-19 pandemic
Dusan Licina, Shen Yang, Akila Muthalagu
Personal cloud, termed as the difference in air pollutant concentrations between breathing zone and room sites, represents the bias in approximating personal inhalation exposure that is linked to accuracy of health risk assessment. This study performed a t ...
PERGAMON-ELSEVIER SCIENCE LTD2023Wintertime vertical distribution of air pollution in suburban Fairbanks during the ALPACA 2022 field campaign
Julia Schmale, Andrea Baccarini, Roman Pohorsky
The Alaskan Layered Pollution and Chemical Analysis (ALPACA) field campaign investigated the sources and processing of wintertime urban pollution in Fairbanks, Alaska in January and February 2022. Several sites located around the city of Fairbanks collecte ...
2023Adequacy of stationary measurements as proxies for residential personal exposure to gaseous and particle air pollutants
People are exposed to myriad of airborne pollutants in their homes. Owing to diverse potential sources of air pollution and human activity patterns, accurate assessment of residential exposures is complex. In this study, we explored the relationship betwee ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2023Clean air policies are key for successfully mitigating Arctic warming
A tighter integration of modeling frameworks for climate and air quality is urgently needed to assess the impacts of clean air policies on future Arctic and global climate. We combined a new model emulator and comprehensive emissions scenarios for air poll ...
2022The framework for improving air quality monitoring over Indian cities
Athanasios Nenes, Satoshi Takahama, Arindam Roy
Indian air quality monitoring guideline is directly adopted from World Health Organization (1977) guidelines without place-based modification. According to Indian air quality guidelines (2003), the location of monitoring sites should be determined from air ...
2022Source and Chemistry of Hydroxymethanesulfonate (HMS) in Fairbanks, Alaska
Fairbanks, Alaska, is a subarctic city with fine particle (PM2.5) concentrations that exceed air quality regulations in winter due to weak dispersion caused by strong atmospheric inversions, local emissions, and the unique chemistry occurring under the col ...
AMER CHEMICAL SOC2022High-resolution hybrid inversion of IASI ammonia columns to constrain US ammonia emissions using the CMAQ adjoint model
Athanasios Nenes, Jennifer Kaiser
Ammonia (NH3) emissions have large impacts on air quality and nitrogen deposition, influencing human health and the well-being of sensitive ecosystems. Large uncertainties exist in the "bottom-up" NH3 emission inventories due to limited source information ...
COPERNICUS GESELLSCHAFT MBH2021Nighttime chemistry of biomass burning emissions in urban areas: A dual mobile chamber study
Athanasios Nenes, Spyros Pandis
Residential biomass burning for heating purposes is an important source of air pollutants during winter. Here we test the hypothesis that significant secondary organic aerosol production can take place even during winter nights through oxidation of the emi ...
