| Abstract | Heterogeneous chemical cycles of pyrogenic nitrogen and halides influence tropospheric ozone and affect the stratosphere during extreme Pyrocumulonimbus (PyroCB) events. We report field-derived N2O5 uptake coefficients, gamma(N2O5), and ClNO2 yields, phi(ClNO2), from two aircraft campaigns observing fresh smoke in the lower and mid troposphere and processed/aged smoke in the upper troposphere and lower stratosphere (UTLS). Derived phi(ClNO2) varied across the full 0-1 range but was typically |
