| Zusammenfassung |
| This paper presents extensive {bias determination} analyses of
ozone observations from the Atmospheric Chemistry Experiment (ACE) satellite
instruments: the ACE Fourier Transform Spectrometer (ACE-FTS) and the Measurement
of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation
(ACE-MAESTRO) instrument. Here we compare the latest ozone data products
from ACE-FTS and ACE-MAESTRO with coincident observations from nearly 20
satellite-borne, airborne, balloon-borne and ground-based instruments,
by analysing volume mixing ratio profiles and partial column densities. The
ACE-FTS version 2.2 Ozone Update product reports more ozone than most
correlative measurements from the upper troposphere to the lower mesosphere.
At altitude levels from 16 to 44 km, the average values of the
mean relative differences are nearly all within +1 to +8%.
At higher altitudes (45–60 km), the ACE-FTS ozone amounts
are significantly larger than those of the comparison instruments,
with mean relative differences of up to +40% (about +20% on average).
For the ACE-MAESTRO version 1.2 ozone data
product, mean relative differences are within ±10% (average
values within ±6%) between
18 and 40 km for both the sunrise and sunset measurements.
At higher altitudes (~35–55 km), systematic biases of opposite sign
are found between the ACE-MAESTRO sunrise and sunset observations. While
ozone amounts derived from the ACE-MAESTRO sunrise occultation data are often
smaller than the coincident observations (with mean relative
differences down to −10%), the sunset occultation profiles for ACE-MAESTRO
show results that are qualitatively similar to ACE-FTS, indicating
a large positive bias (mean relative differences within +10 to
+30%) in the 45–55 km altitude range. In contrast, there is no significant
systematic difference in bias found for the ACE-FTS sunrise and
sunset measurements. |
