Seminar: Michal Galkowski

The presentation will comprise two sections, with the overarching theme of greenhouse gases' atmospheric transport in the lower troposphere. The focus will be on how the mixing height dynamics affect the observed and simulated tracer distributions.

In the first segment, I'll present how we use WRF simulations of CH4 over the MacKenzie River Delta to understand and explain observations from the HALO research aircraft in August 2022. I'll focus on how we can show how the interplay of nighttime transport dynamics, coastal effects and the diurnal PBL cycle affects the model's ability to match real observations. In the second part, I'm going to discuss how we're currently diagnosing PBL heights in Europe over larger areas, and how we are working towards using this information in the modelling systems employed in the ATM group. I'll mention challenges and opportunities for the near future, including plans for the proposed ITMS Phase 2 project.
