Vertical profiles of NO2 and NO have been obtained from
solar occultation measurements by the Atmospheric Chemistry Experiment
(ACE), using an infrared Fourier Transform Spectrometer (ACE-FTS) and
(for NO2) an ultraviolet-visible-near-infrared spectrometer, MAESTRO (Measurement of
Aerosol Extinction in the Stratosphere and Troposphere Retrieved by
Occultation). In this paper, the quality of the ACE-FTS version 2.2
NO2 and NO and the MAESTRO version 1.2 NO2 data
are assessed using other solar occultation measurements (HALOE,
SAGE II, SAGE III, POAM III, SCIAMACHY), stellar occultation
measurements (GOMOS), limb measurements (MIPAS, OSIRIS), nadir
measurements (SCIAMACHY), balloon-borne measurements (SPIRALE, SAOZ) and
ground-based measurements (UV-VIS, FTIR).
Time differences between the comparison measurements were reduced using either a tight coincidence
criterion, or where possible, chemical box models.
ACE-FTS NO2 and NO and the MAESTRO NO2 are generally consistent with
the correlative data. The ACE-FTS and MAESTRO NO2
volume mixing ratio (VMR) profiles agree with the profiles from other
satellite data sets to within about 20% between 25 and 40 km, with
the exception of MIPAS ESA (for ACE-FTS) and SAGE II (for
ACE-FTS (sunrise) and MAESTRO) and suggest a negative bias between 23 and 40 km of about 10%.
MAESTRO reports larger VMR values than the ACE-FTS.
In comparisons with HALOE, ACE-FTS NO VMRs typically (on average) agree to
±8% from 22 to 64 km and to +10% from
93 to 105 km, with maxima of 21% and 36%, respectively. Partial column comparisons for NO2 show
that there is quite good agreement between the ACE instruments and the FTIRs,
with a mean difference of +7.3% for ACE-FTS and +12.8% for MAESTRO. |
