"Atmospheric ammonia constrained by satellite observations"


Vortrag im Rahmen des Meteorologisch-Geophysikalischen Kolloquiums.



Abstract: Atmospheric ammonia has received a lot of attention as a significant anthropogenic contaminant. It causes a series of cascading negative effects for the ecosystem, due to acidification of soils and eutrophication of reservoirs, as well as human health, because it is a precursor of PM2.5 formation. For these reasons, international policies have been initiated towards reduction of ammonia emissions. During the last decade, several satellite products (such as IASI, AIRS, CrIS, TES etc.) have also been developed in an effort to identify global levels of ammonia considering that the relatively sparse existing monitoring network has an insufficient coverage for this purpose. Here, we are showing an effort to calculate emissions of NH3 based on these products also recording the impact of the recent pandemic.
