"I study the air in the stratosphere and the upper part of the troposphere. I want to try and explain variations in the prevalence of aerosol particles, and I have recently become interested in the stratospheric zone" explains Johan Friberg, researcher at MERGE (ModElling the Regional and Global Earth system) at Lund University. The troposphere is the lowest layer of the Earth's atmosphere, and it contains three quarters of the atmosphere's total mass, including almost all water vapour and aerosol particles.
