Remote sensing of atmospheric trace gases over coastal environments using fixed and shipborne Pandoras 

Nitrogen dioxide (NO2) pollution remains a serious global problem, particularly near highly populated urbanized coasts that face increasing challenges with climate change. Yet, the combined impact of urban emissions, pollution transport, and complex meteorology on the spatiotemporal dynamics of NO2 along heterogeneous urban coastlines remains poorly characterized. The Tzortziou Bio-Optics Lab integrates measurements from different platforms – boats, ground-based networks, aircraft and satellites – to characterize total column NO2 (TCNO2) dynamics across the land-water continuum in heavily urbanized and rural systems.
