Reactive Nitrogen in the Upper Troposphere (ERC UpTrop)

Central to the influence of the upper troposphere on the global troposphere is reactive nitrogen. Here we develop a climatology of reactive nitrogen in the upper troposphere using observations from aircraft and space-based instruments, interpreted with the GEOS-Chem chemical transport model, to address glaring and persistent biases in our understanding of the upper troposphere.
