| Zusammenfassung |
| We present the results of an extensive validation program of the
most recent version of ozone vertical profiles retrieved with the
IMK/IAA (Institute for Meteorology and Climate Research/Instituto de Astrofísica de Andalucía)
MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) research level 2 processor from version 5 spectral
level 1 data. The time period covered corresponds to the reduced
spectral resolution period of the MIPAS instrument, i.e., January
2005–April 2012. The comparison with satellite instruments includes
all post-2005 satellite limb and occultation sensors that have measured
the vertical profiles of tropospheric and stratospheric ozone:
ACE-FTS, GOMOS, HALOE, HIRDLS, MLS, OSIRIS, POAM, SAGE II,
SCIAMACHY, SMILES, and SMR. In addition, balloon-borne MkIV solar
occultation measurements and ground-based Umkehr measurements have
been included, as well as two nadir sensors: IASI and SBUV. For
each reference data set, bias determination and precision assessment
are performed. Better agreement with reference instruments than for the previous
data version, V5R_O3_220 (Laeng et al., 2014), is found: the known
high bias around the ozone vmr (volume mixing ratio) peak is significantly reduced and the
vertical resolution at 35 km has been improved. The agreement
with limb and solar occultation reference instruments
that have a known small bias vs. ozonesondes is within 7% in
the lower and middle stratosphere and 5% in the upper
troposphere. Around the ozone vmr peak, the agreement with most of
the satellite reference instruments is within 5%; this bias is as
low as 3% for ACE-FTS, MLS, OSIRIS, POAM and SBUV. |
