Understanding the pressure tiny particles face and how it affects their development
Millions of solid particles and liquid droplets are present in the air we breathe. From pollen to volcanic ash to sea salt, aerosols are ubiquitous. Natural and human-made aerosols have important impact on climate, largely through effects on cloud formation and absorbance or reflection of the Sun's energy. However, they are one of the biggest sources of uncertainty in climate models. The EU-funded MAARvEL project is focusing on the smallest particles and the effects of Laplace pressure on their formation, distribution, and properties. This system has not been studied at all to date. Insight will improve the accuracy of climate models, leading to higher predictive power and enhanced ability to meet one of the greatest challenges of the century.
