| This paper characterizes vertical ozone profiles retrieved with the IMK-IAA
(Institute for Meteorology and Climate Research, Karlsruhe – Instituto de
Astrofisica de Andalucia) science-oriented processor from high spectral
resolution data (until March 2004) measured by the Michelson Interferometer
for Passive Atmospheric Sounding (MIPAS) aboard the environmental satellite
Envisat. Bias determination and precision validation is performed on the
basis of correlative
measurements by ground-based lidars, Fourier transform infrared spectrometers,
and microwave radiometers as well as balloon-borne ozonesondes, the
balloon-borne version of MIPAS, and two satellite instruments (Halogen
Occultation Experiment and Polar Ozone and Aerosol Measurement III).
Percentage mean differences between MIPAS and the comparison instruments for
stratospheric ozone are generally within ±10%. The precision in this
altitude region is estimated at values between 5 and 10% which gives an
accuracy of 15 to 20%.
Below 18 km, the spread of the percentage mean differences is larger and
the precision degrades to values of more than 20% depending on altitude
and latitude. The main reason for the degraded precision at low altitudes is
attributed
to undetected thin clouds which affect MIPAS retrievals, and to the
influence of uncertainties in the water vapor concentration. |
