Data sets

Global, regional and national trends of atmospheric ammonia derived from a decadal (2008–2018) satellite record ( M. Van Damme, L. Clarisse, B. Franco, M. A. Sutton, J. W. Erisman, R. Wichink Kruit, M. van Zanten, S. Whitburn, J. Hadji-Lazaro, D. Hurtmans, C. Clerbaux, and P.-F. Coheur

Short summary
Large cities can experience high levels of fine particulate matter (PM2.5) pollution linked to ammonia (NH3) mainly emitted from agricultural activities. Using a combination of PM2.5 and NH3 measurements from in situ instruments, satellite infrared spectrometers, and atmospheric model simulations, we have demonstrated the role of NH3 and meteorological conditions on pollution events occurring over Paris, Toronto, and Mexico City.
