The effects of ozone depletion, increased greenhouse gas emissions, and increased aerosols on precipitation in High-Mountain Asia
High-Mountains Asia (HMA) forms the largest mountain mass on Earth and provides the water needs for more than one billion people living in downstream regions. They play a crucial role by interacting with regional atmospheric circulations, such as the summe ...
2017Microphysical explanation of the RH-dependent water affinity of biogenic organic aerosol and its importance for climate
A large fraction of atmospheric organic aerosol (OA) originates from natural emissions that are oxidized in the atmosphere to form secondary organic aerosol (SOA). Isoprene (IP) and monoterpenes (MT) are the most important precursors of SOA originating fro ...
Blackwell Publishing Ltd2017Modeling regional air quality and climate: Improving organic aerosol and aerosol activation processes in WRF/Chem version 3.7.1
Air quality and climate influence each other through the uncertain processes of aerosol formation and cloud droplet activation. In this study, both processes are improved in the Weather, Research and Forecasting model with Chemistry (WRF/Chem) version 3.7. ...
Copernicus GmbH2017Biomass-burning impact on CCN number, hygroscopicity and cloud formation during summertime in the eastern Mediterranean
This study investigates the concentration, cloud condensation nuclei (CCN) activity and hygroscopic properties of particles influenced by biomass burning in the eastern Mediterranean and their impacts on cloud droplet formation. Air masses sampled were sub ...
Copernicus GmbH2016Isoprene suppression of new particle formation: Potential mechanisms and implications
Secondary aerosols formed from anthropogenic pollutants and natural emissions have substantial impacts on human health, air quality, and the Earth’s climate. New particle formation (NPF) contributes up to 70% of the global production of cloud condensation ...
Wiley-Blackwell2016Incorporation of advanced aerosol activation treatments into CESM/CAM5: Model evaluation and impacts on aerosol indirect effects
Yi Zhang, Athanasios Nenes, Xiuwei Zhang
One of the greatest sources of uncertainty in the science of anthropogenic climate change is from aerosol-cloud interactions. The activation of aerosols into cloud droplets is a direct microphysical linkage between aerosols and clouds; parameterizations of ...
Copernicus GmbH2014Sensitivity of air quality to potential future climate change and emissions in the United States and major cities
Simulated present and future air quality is compared for the years 2006-2010 and 2048-2052 over the contiguous United States (CONUS) using the Community Multi-scale Air Quality (CMAQ) model. Regionally downscaled present and future climate results are deve ...
Elsevier Ltd2014Understanding the contributions of aerosol properties and parameterization discrepancies to droplet number variability in a global climate model
Aerosol indirect effects in climate models strongly depend on the representation of the aerosol activation process. In this study, we assess the process-level differences across activation parameterizations that contribute to droplet number uncertainty by ...
European Geosciences Union2014Climatic effects of 1950-2050 changes in US anthropogenic aerosols-Part 1: Aerosol trends and radiative forcing
We calculate decadal aerosol direct and indirect (warm cloud) radiative forcings from US anthropogenic sources over the 1950-2050 period. Past and future aerosol distributions are constructed using GEOS-Chem and historical emission inventories and future p ...
2012Climatic effects of 1950-2050 changes in US anthropogenic aerosols-Part 2: Climate response
We investigate the climate response to changing US anthropogenic aerosol sources over the 1950-2050 period by using the NASA GISS general circulation model (GCM) and comparing to observed US temperature trends. Time-dependent aerosol distributions are gene ...
