Biography

After finishing my university studies in Atmospheric Physics in Bologna, I moved to Bremen for a PhD on stratospheric ozone retrievals. I stayed there as a Postdoc within an ESA Living Planet Fellowship, which gave me the opportunity to continue the research on ozone long-term trends and collaborate with the University of Leeds and NASA. Currently I am part of the OREGANO project and I am visiting ESRIN for 6 months.

Research

Tropospheric ozone is a relevant pollutant harmful for human health and vegetation. Approximately 30% of the tropospheric ozone burden is related to human activity, in particular to the emission of ozone precursors, such as NOx, in combination with the presence of Volatile Organic Compounds and intense sunlight. This project aims at comparing a long-term tropospheric ozone column (TrOC) data set produced at the University of Bremen with other products, such as TROPOMI observations. In addition, causal links between precursors and ozone concentration as observed from satellite data will be investigated. Finally, another point of interest is related to long-term TrOC changes, with a focus on the relevant variables (proxies) that shall be included in the regression model to compute trends.
