Anthropogenic emissions and land use changes have modified atmospheric aerosol
concentrations and size distributions over time. Understanding preindustrial conditions and …

Climate change and air pollution are critical environmental issues both in the here and now
and for the coming decades. A recent OECD report found that unless action is taken, air …

Short‑lived climate forcers (SLCFs) affect climate and are, in most cases, also air pollutants.
They include aerosols (sulphate, nitrate, ammonium, carbonaceous aerosols, mineral dust …

Executive summary Land and climate interact in complex ways through changes in forcing
and multiple biophysical and biogeochemical feedbacks across different spatial and …

Poor air quality is globally the largest environmental health risk. Epidemiological studies
have uncovered clear relationships of gaseous pollutants and particulate matter (PM) with …

Poor air quality is currently responsible for large impacts on human health across the world.
In addition, the air pollutants ozone (O3) and particulate matter less than 2.5 µm in diameter …

Secondary organic aerosols (SOA) are a large source of uncertainty in our current
understanding of climate change and air pollution. The phase state of SOA is important for …

Uncertainty in the representation of biomass burning (BB) aerosol composition and optical
properties in climate models contributes to a range in modeled aerosol effects on incoming …

Within the framework of the AeroCom (Aerosol Comparisons between Observations and
Models) initiative, the state-of-the-art modelling of aerosol optical properties is assessed …

This paper presents a summary of the work done within the European Union's Seventh
Framework Programme project ECLIPSE (Evaluating the Climate and Air Quality Impacts of …
