| COMMENTS: | The absorption cross sections of N2O5 were investigated
by balloon-borne observations of the relevant trace gases in the tropical mid-stratosphere
The method relies on the observation of the diurnal variation of NO2 by limb scanning DOAS (differential optical absorption spectroscopy) measurements
supported by detailed photochemical modelling of NOy (NOx(= NO+NO2) +NO3 + 2N2O5 + ClONO2 + HO2NO2 + BrONO2 +HNO3) photochemistry and a non-linear least square fitting of the model result to the NO2 observations
Best agreement between the simulated and observed diurnal increase of NO2 is found if the absorption cross sections of N2O5, as recommended by

are scaled by a factor of 1.6 ± 0.8 in the UV-C (200–260 nm) and by a factor of 0.9 ± 0.26 in the UV-B/A (260–350 m)
Absorption cross sections have been obtained by personal communication from Lena Kritten (January 2015) |
