Project description
In this project we will ambitiously study in both laboratory and real atmospheric conditions how the interactions of OA with water vapour, both at sub- and supersaturation conditions, change the particle composition and the most atmospherically relevant properties of the particles. This is vital to understand the evolution of OA in the atmosphere. We will specifically concentrated on environments typical for Boreal area. We will utilize an extensive set of existing online mass spectrometer techniques and other state of the art instrumentation as well as develop new methodology to achieve the ultimate goal of the study: the first comprehensive parameterization applicable in global climate models to describe changes in OA mass, composition and properties due to the aqueous phase processing both in subsaturation and in-cloud conditions.
