Abstract
[1] NO3 vertical profiles have been retrieved over the Antarctic (60 –90 S) from the
Scanning Imaging Absorption Spectrometer for Atmospheric Cartography
(SCIAMACHY) lunar occultation spectra, using the visible spectral band (610–680 nm)
containing NO3 absorption bands at 623 and 662 nm. The retrieved NO3 profiles agree
well with calculations from a photochemical model constrained by retrieved O3 and
analyzed temperatures in the altitude range between 24 and 45 km. Below about
35–40 km, observed NO3 is well reproduced by photochemical steady state calculations.
Differences between observed and modeled NO3 are within the estimated accuracy of
20–35%, demonstrating the consistency of the NO3 retrieval and model.
