Short summary

This study presents a global budget of tropospheric reactive oxidized nitrogen (NO_y) based on the GEOS‑Chem chemical transport model evaluated against ATom aircraft observations. In addition to burdens, deposition, and lifetimes, we detail the magnitudes of the chemical fluxes governing cycling between NO_y species, including uncertain heterogeneous processes such as aerosol nitrate photolysis and organic nitrate hydrolysis.
