Novel method for measuring gaseous emission dynamics from open sources

PhD defence, Friday 13 January 2023. Yolanda Maria Lemes Perschke

Yolanda Maria Lemes Perschke

During her Ph.D studies, Yolanda M. Lemes covered findings in the field of measurement methods for ammonia (NH3) and methane (CH4) emissions from agricultural sources, documentation of emissions from farm-scale sources, and mitigation techniques for reducing emissions from manure storage systems.

Her thesis assessed a novel measuring system that uses line-average concentration measurements with a closed analyzer, specifically a cavity ring-downspectroscopy (CRDS). This novel measurement approach, together with the well-established IDM, enables quantification of NH3 and CH4 emissions from farm-scale agricultural sources: slurry tanks, manure stockpiles, and a whole farm.

The PhD study was completed at Department of Biological and Chemical Engineering, Aarhus University, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
