Development of Models for the Cosmogenic Isotopes Transport in the Earth's Atmosphere

My research focuses on the development of global models that describe the production, transport, and deposition of cosmogenic isotopes - such as beryllium-10, carbon-14, and chlorine-36 - in the Earth's atmosphere. These isotopes are formed through interactions between cosmic rays and atmospheric constituents, and they serve as valuable tracers in studies of solar activity, geomagnetic field variations, and climate change over millennial timescales.

A key aspect of this work involves modeling the complex transport mechanisms that govern the distribution of isotopes from their point of production in the upper atmosphere to their eventual deposition on the Earth’s surface. This includes incorporating the dynamics of stratosphere-troposphere exchange, large-scale atmospheric circulation, and processes such as wet and dry deposition. My favourite tool is the chemistry climate model SOCOL.
