Profiles have been retrieved for species with pressure dependent absorption lines like CH4, N2O, HCl, HF, HNO3, NO, and and O3. Just as an example profiles of O3, HF, and HCl are shown:
Fig.1: O3 profile
as measured with ground-based FTIR at Kiruna on 2001-07-08.
Fig.2: HF profile
as measured with ground-based FTIR at Kiruna on 2001-07-08.
Fig.3: HCl profile as measured with ground-based FTIR at Kiruna on 2001-07-08.
Time series of profiles and
column amounts of several species have been derived.
Figs. 4 + 5 show examples for Kiruna in winter 1997/98:

during winter 1997/98, compared with model results obtained with
KASIMA
(KArlsruhe SImulation Model of the middle Atmosphere).
Fig.5: Time series of zenith column amounts of HNO3
during winter 1997/98, compared with model results obtained with
KASIMA
(KArlsruhe SImulation Model of the middle Atmosphere).
