Dr Carly Reddington

Profile

I am Research Fellow in the Institute for Climate and Atmospheric Science (ICAS) and a member of the Biosphere Atmosphere Group and the Atmospheric Chemistry and Aerosols research group. My Research Fellow position is supported by a gift from AIA Group Ltd as part of the Air Quality in Asia Project. My research involves using complex atmospheric chemistry-aerosol models to investigate the impact of anthropogenic and natural emissions on atmospheric composition and air quality.

Research interests

My primary research interest is to investigate how air pollutant emissions change the composition of the atmosphere, degrade regional air quality, and negatively impact public health. I am passionate about conducting research that has an impact beyond the scientific community and can be used to inform policy and practice.

Current research

Research Highlights

Impacts of policy scenarios on air quality and public health in the Greater Bay Area, China

1. PM_2.5 exposure inside the Greater Bay Area (GBA) is strongly controlled by emissions outside the GBA (Conibear, Reddington et al., 2021).
2. Reductions in residential solid fuel use and agricultural emissions result in the greatest reductions in PM_2.5 exposure and the largest health benefits (Conibear, Reddington et al., 2021).

Examining major sources of air pollution in Asia

1. Emissions from industry and residential cooking and heating make the largest to particulate air pollution in China (Reddington et al., 2019).
2. Eliminating emissions from the residential sector would avert 467,000 (95 % uncertainty interval (95UI): 409,000–542,000) annual premature deaths across India, China, and Southeast Asia (Reddington et al., 2019).

Deforestation, fires and air quality

1. Particulate air pollution from forest and vegetation fires disproportionately effects poorer populations in Southeast Asia. Preventing these fires would substantially improve air quality and reduce exposure to air pollution (Reddington et al., 2021).
2. Reductions in fires associated with deforestation in Brazil between 2004 and 2012, caused regional particulate air pollution to decline by ~30% during the dry season. This reduction in air pollution would have a considerable public health benefit across South America (Reddington et al., 2015).
3. Deforestation and peat fires in Sumatra account for 75% of the smoke pollution in Singapore; improved fire management in Indonesia would improve local and regional air quality (Reddington et al., 2014).

Previous research

The South American Biomass Burning Analysis (SAMBBA) Project: Investigating the properties and impacts of tropical biomass burning aerosol. For this project I used a global aerosol microphysics model and a variety of observations in the Amazon region to improve understanding of aerosol emissions from vegetation fires (Reddington et al., 2016; 2019). I also used these tools to quantify the effects of biomass burning on atmospheric composition, regional air quality and human health (Reddington et al., 2014; 2015).

The Global Synthesis Science Project (GASSP): Constraining uncertainty in global aerosol models. This this project I synthesised a vast database of diverse aerosol measurements from aircraft, ground stations and ships (Reddington et al., 2017), which is being used in combination with statistical methods to evaluate global aerosol and climate models and constrain their uncertainties.

PhD Project. During my PhD I investigated primary and secondary sources of atmospheric aerosol over Europe using a global atmospheric chemistry-transport model (Reddington et al., 2011; 2013).
